Allerdings steht er nur wenige Fingerbreit über dem Horizont in der Dunstschicht, das erschwert das Auffinden. Vielen Dank für's Teilen:. Auch weil die Schmuggler in Zeiten von Corona sehr kreativ sind, andere Wege zu gehen. In der folgenden Nacht ist der Mond fast mittig unter den beiden Planeten zu sehen, mit je etwa zwei Fingerbreit Abstand.

He found that after observation biases were accounted for, the clustering of longitudes of perihelion of 10 known eTNOs would be observed only 1.

When combined with the odds of the observed clustering of the arguments of perihelion, the probability was 0. Simulations of 15 known objects evolving under the influence of Planet Nine also revealed differences from observations.

Their simulations also showed that the perihelia of the eTNOs rose and fell smoothly, leaving many with perihelion distances between 50 AU and 70 AU where none had been observed, and predicted that there would be many other unobserved objects.

Many of the objects were also ejected from the Solar System after encountering the other giant planets.

The large unobserved populations and the loss of many objects led Shankman et al. Ann-Marie Madigan and Michael McCourt postulate that an inclination instability in a distant massive belt is responsible for the alignment of the arguments of perihelion of the eTNOs.

The self-gravity of this disk would cause its spontaneous organization, increasing the inclinations of the objects and aligning the arguments of perihelion, forming it into a cone above or below the original plane.

Instead, the simulation produced a rapid precession of the objects' orbits and most of the objects were ejected on too short of a timescale for an inclination instability to occur.

Antranik Sefilian and Jihad Touma propose that a massive disk of moderately eccentric TNOs is responsible for the clustering of the longitudes of perihelion of the eTNOs.

This disk would contain 10 Earth-mass of TNOs with aligned orbits and eccentricities that increased with their semimajor axes ranging from zero to 0.

The gravitational effects of the disk would offset the forward precession driven by the giant planets so that the orbital orientations of its individual objects are maintained.

The orbits of objects with high eccentricities, such as the observed eTNOs, would be stable and have roughly fixed orientations, or longitudes of perihelion, if their orbits were anti-aligned with this disk.

The Planet Nine hypothesis includes a set of predictions about the mass and orbit of the planet. An alternative theory predicts a planet with different orbital parameters.

The eccentricity is limited in this case by the requirement that close approaches of GB to the planet be avoided. Unlike Batygin and Brown, Malhotra, Volk and Wang do not specify that most of the distant detached objects would have orbits anti-aligned with the massive planet.

These simulations showed the basic idea of how a single large planet can shepherd the smaller TNOs into similar types of orbits.

They were basic proof of concept simulations that did not obtain a unique orbit for the planet as they state there are many possible orbital configurations the planet could have.

Their work is very similar to how Alexis Bouvard noticed Uranus' motion was peculiar and suggested that it was likely gravitational forces from an unknown 8th planet, which led to the discovery of Neptune.

Aarseth confirmed that the observed alignment of the arguments of perihelion could not be due to observational bias.

Due to its extreme distance from the Sun, Planet Nine would reflect little sunlight, potentially evading telescope sightings.

At aphelion, the largest telescopes would be required, but if the planet is currently located in between, many observatories could spot Planet Nine.

A study estimated that Planet Nine, if it exists, may be smaller and closer than originally thought.

The search of databases of stellar objects by Batygin and Brown has already excluded much of the sky along Planet Nine's predicted orbit.

The remaining regions include the direction of its aphelion, where it would be too faint to be spotted by these surveys, and near the plane of the Milky Way , where it would be difficult to distinguish from the numerous stars.

Other researchers have been conducting searches of existing data. David Gerdes, who helped develop the camera used in the Dark Energy Survey , claims that software designed to identify distant Solar System objects such as UZ could find Planet Nine if it was imaged as part of that survey, which covered a quarter of the southern sky.

Using a supercomputer they will offset the images to account for the calculated motion of Planet Nine, allowing many faint images of a faint moving object to be combined to produce a brighter image.

This search covered regions of the sky away from the galactic plane at the "W1" wavelength the 3. Because the planet is predicted to be visible in the Northern Hemisphere , the primary search is expected to be carried out using the Subaru Telescope , which has both an aperture large enough to see faint objects and a wide field of view to shorten the search.

In late April and Early May Scott Lawrence proposed the latter method for finding it as multiple spacecraft would have advantages that land-based telescopes don't have.

Although a distant planet such as Planet Nine would reflect little light, due to its large mass it would still be radiating the heat from its formation as it cools.

The project will also search for substellar objects like brown dwarfs in the neighborhood of the Solar System. By looking for moving objects in the animations, citizen scientists might find Planet Nine.

In April , [] using data from the SkyMapper telescope at Siding Spring Observatory , citizen scientists on the Zooniverse platform reported four candidates for Planet Nine.

These candidates will be followed up on by astronomers to determine their viability. Precise observations of Saturn's orbit using data from Cassini suggest that Planet Nine could not be in certain sections of its proposed orbit because its gravity would cause a noticeable effect on Saturn's position.

This data neither proves nor disproves that Planet Nine exists. The analysis, using Batygin and Brown's orbital parameters for Planet Nine, suggests that the lack of perturbations to Saturn's orbit is best explained if Planet Nine is located at a true anomaly of A later analysis of Cassini data by astrophysicists Matthew Holman and Matthew Payne tightened the constraints on possible locations of Planet Nine.

Holman and Payne developed a more efficient model that allowed them to explore a broader range of parameters than the previous analysis.

The parameters identified using this technique to analyze the Cassini data was then intersected with Batygin and Brown's dynamical constraints on Planet Nine's orbit.

William Folkner, a planetary scientist at the Jet Propulsion Laboratory JPL , has stated that the Cassini spacecraft is not experiencing unexplained deviations in its orbit around Saturn.

An undiscovered planet would affect the orbit of Saturn, not Cassini. This could produce a signature in the measurements of Cassini , but JPL has seen no unexplained signatures in Cassini data.

An analysis in of Pluto's orbit by Holman and Payne found perturbations much larger than predicted by Batygin and Brown's proposed orbit for Planet Nine.

An analysis of the orbits of comets with nearly parabolic orbits identifies five new comets with hyperbolic orbits that approach the nominal orbit of Planet Nine described in Batygin and Brown's initial article.

Malena Rice and Gregory Laughlin have proposed that a network of telescopes be built to detect occultations by Jupiter Trojans.

The timing of these occultations would provide precise astrometry of these objects enabling their orbits to be monitored for variations due to the tide from Planet Nine.

An analysis by Sarah Millholland and Gregory Laughlin identified a pattern of commensurabilities ratios between orbital periods of pairs of objects consistent with both being in resonance with another object of the eTNOs.

Carlos and Raul de la Fuente Marcos also note commensurabilities among the known eTNOs similar to that of the Kuiper belt, where accidental commensurabilities occur due to objects in resonances with Neptune.

These objects would be in resonance and anti-aligned with Planet Nine if it had a semi-major axis of AU, below the range proposed by Batygin and Brown.

Alternatively, they could be in resonance with Planet Nine, but have orbital orientations that circulate instead of being confined by Planet Nine if it had a semi-major axis of AU.

A later analysis by Elizabeth Bailey, Michael Brown and Konstantin Batygin found that if Planet Nine is in an eccentric and inclined orbit the capture of many of the eTNOs in higher order resonances and their chaotic transfer between resonances prevent the identification of Planet Nine's semi-major axis using current observations.

Planet Nine does not have an official name and will not receive one unless its existence is confirmed via imaging. Only two planets, Uranus and Neptune, have been discovered in our solar system during recorded history.

However, many minor planets , including dwarf planets such as Pluto, asteroids , and comets have been discovered and named. Consequently, there is a well-established process for naming newly discovered solar system objects.

If Planet Nine is observed, the International Astronomical Union will certify a name, with priority usually given to a name proposed by its discoverers.

In their original article, Batygin and Brown simply referred to the object as "perturber", [1] and only in later press releases did they use "Planet Nine".

Brown has stated: "We actually call it Phattie [Q] when we're just talking to each other. In , an article titled Planet Nine from Outer Space about the hypothesized planet in the outer region of the Solar System was published in Scientific American.

Persephone , the wife of the deity Pluto, had been a popular name commonly used in science fiction for a planet beyond Neptune see Fictional planets of the Solar System.

However, it is unlikely that Planet Nine or any other conjectured planet beyond Neptune will be given the name Persephone once its existence is confirmed, as it is already the name for asteroid Persephone.

In , planetary scientist Alan Stern objected to the name Planet Nine , saying, "It is an effort to erase Clyde Tombaugh 's legacy and it's frankly insulting", suggesting the name Planet X until its discovery.

Our prediction is not related to this prediction. From Wikipedia, the free encyclopedia. This article is about the hypothetical planet first suggested in For other uses, see Ninth planet disambiguation.

If M were equal to 1 Earth mass, then long-lived apsidally anti-aligned orbits would indeed occur, but removal of unstable orbits would happen on a much longer timescale than the current evolution of the Solar System.

Hence, even though they would show preference for a particular apsidal direction, they would not exhibit true confinement like the data.

They also note that M greater than 10 Earth mass would imply a longer semi-major axis. Hence they estimate that the mass of the object is likely in the range of 5 to 15 Earth mass.

If there are no close encounters with Planet Nine, which would change the energy of the orbit, the object's orbital elements remain on one of these curves as the orbits evolve.

In the Nice model 20—50 Earth masses is estimated to have been ejected, a significant mass is also ejected from the neighborhoods of the giant planets during their formation.

Brightest in Saturn will be at its brightest between July 4 and Aug. Saturn is at opposition to the sun on July Saturn will appear close to Mars on March 31 the two worlds will be virtually the same in brightness and will provide in an interesting contrast of colors , and will engage Jupiter in an incredibly close conjunction on Dec.

A small telescope may reveal its tiny, greenish disk. Uranus spends all of in the constellation of Aries the Ram. It can be spotted in the evening sky from Jan.

Uranus returns to the evening sky from Oct. Brightest in Uranus will be brightest from Aug. It will arrive at opposition to the sun on Oct.

Neptune will be visible in the evening from Jan. It returns to the evening sky from Sept. Brightest in Neptune will be at its brightest from July 16 to Nov.

It reaches opposition on Sept. On Jan. Venus will be 63, times brighter than Neptune! Jupiter and Saturn are in conjunction with each other on an average of once about every 20 years.

When they come closest to each other they are usually separated by about a degree or two. But this upcoming get together between the king of the gods and the god of time will be something out of the ordinary, for the two worlds will appear to come exceedingly close to each other.

How close? On the next clear night, check out the Big Dipper and take note of the star in the middle of the handle. That star is Mizar and very near to it is a faint star known as Alcor.

It used to serve as an eye test. If you could see it sitting next to Mizar your vision was considered to be normal.

Mizar and Alcor are separated by 12 arc minutes, but on Dec. It will provide a rare opportunity to see both planets in the same view of a high-powered telescope!

On average, these two planets come as close as this about every years, though the last time dates back to July 16th, !

The only disadvantage is that you will have to look quick. The two planets will be low in the southwest sky as darkness falls and will set less than 2.
