2012 VP113 Inner Oort Cloud Object Discovery Images from Scott S. Sheppard/Carnegie Institution for Science. The discovery of 2012 VP113 occurred on Nov. 5, 2012, and was led by Chadwick Trujillo, from the Gemini Observatory in Hawaii, and Scott Sheppard, from the Carnegie Institution in Washington, D.C. 2012 vp 113 是一顆海王星外天體 。天文學家於2014年3月26日宣布發現2012 vp 113 。2012 vp 113 的絕對星等（h）為4.1等 ，所以它可能是一顆矮行星 。它的大小預計為塞德娜的一半，大約與雨神星相當 。. 2012 VP113 is currently near its closest approach to the Sun, in about 2,000 years it will be over five times further. Some scientists hypothesize that the reason why objects like Sedna and 2012 VP113 have their present orbits is because they were gravitationally scattered there by a much larger object - possibly a very distant undiscovered planet. The 2012VP113 Playing Cards Series with the theme of planets in the galaxy, paints us the beauty of the stars. This is the second deck in this series. The card was inspired by the discovery of Mint dwarf planets by American astronomer Scott: 2012VP113.
This page shows Asteroid 2012 VP113 location and other relevant astronomical data in real time. The celestial coordinates, magnitude, distances and speed are updated in real time and are computed using high quality data sets provided by the JPL Horizons ephemeris service (see acknowledgements for details). The sky map shown below represents a rectangular portion of the sky 60x40 arcminutes wide. By comparison the diameter of the full Moon is about 30 arcmins, so the full horizontal extent of the map is approximately 2 full Moons wide. Depending on the device you are using, the map can be dragged horizondally or vertically using the mouse or touchscreen. The deep sky image in the background is provided by the Digitized Sky Survey (acknowledgements).

Scientists using ground based observatories have discovered an object that is believed to have the most distant orbit found beyond the known edge of our solar system. Named 2012 VP113, the observations of the object — possibly a dwarf planet — were obtained and analyzed with a grant from NASA. A dwarf planet is an object in orbit around the sun that is large enough to have its own gravity pull itself into a spherical, or nearly round, shape.
The detailed findings are published in the March 27 edition of Nature.
These images show the discovery of 2012 VP113 taken about 2 hours apart on Nov. 5, 2012. The motion of 2012 VP113 stands out compared to the steady state background of stars and galaxies.

The observations and analysis were led and coordinated by Chadwick Trujillo of the Gemini Observatory in Hawaii and Scott Sheppard of the Carnegie Institution in Washington. They used the National Optical Astronomy Observatory’s 13-foot (4-meter) telescope in Chile to discover 2012 VP113. The telescope is operated by the Foundation of Universities for Research in Astronomy, under contract with the National Science Foundation. The Magellan 21-foot (6.5-meter) telescope at Carnegie’s Las Campanas Observatory in Chile was used to determine the orbit of 2012 VP113 and obtain detailed information about its surface properties.
“The discovery of 2012 VP113 shows us that the outer reaches of our solar system are not an empty wasteland as once was thought,” said Trujillo, lead author and astronomer. “Instead, this is just the tip of the iceberg telling us that there are many inner Oort Cloud bodies awaiting discovery. It also illustrates how little we know about the most distant parts of our solar system and how much there is left to explore.”
Our known solar system consists of the rocky planets like Earth, which are close to the sun; the gas giant planets, which are further out; and the frozen objects of the Kuiper belt, which lie just beyond Neptune’s orbit. Beyond this, there appears to be an edge to the solar system where only one object somewhat smaller than Pluto, Sedna, was previously known to inhabit for its entire orbit. But the newly found 2012 VP113 has an orbit that stays even beyond Sedna, making it the furthest known in the solar system.
Sedna was discovered beyond the Kuiper Belt edge in 2003, and it was not known if Sedna was unique, as Pluto once was thought to be before the Kuiper Belt was discovered in 1992. With the discovery of 2012 VP113, Sedna is not unique, and 2012 VP113 is likely the second known member of the hypothesized inner Oort cloud. The outer Oort cloud is the likely origin of some comets.
“The search for these distant inner Oort cloud objects beyond Sedna and 2012 VP113 should continue, as they could tell us a lot about how our solar system formed and evolved,” says Sheppard.
Sheppard and Trujillo determine that about 900 objects with orbits like Sedna and 2012 VP113 with sizes larger than 621 miles (1000 km) may exist. 2012 VP113 is likely one of hundreds of thousands of distant objects that inhabit the region in our solar system scientists refer to as the inner Oort cloud. The total population of the inner Oort cloud is likely bigger than that of the Kuiper Belt and main asteroid belt.
“Some of these inner Oort cloud objects could rival the size of Mars or even Earth,” said Sheppard. This is because many of the inner Oort cloud objects are so distant that even very large ones would be too faint to detect with current technology.”
2012 VP113’s closest orbit point to the sun brings it to about 80 times the distance of the Earth from the sun, a measurement referred to as an astronomical unit or AU. The rocky planets and asteroids exist at distances ranging between .39 and 4.2 AU. Gas giants are found between 5 and 30 AU, and the Kuiper belt (composed of hundreds of thousands of icy objects, including Pluto) ranges from 30 to 50 AU. In our solar system there is a distinct edge at 50 AU. Until 2012 VP113 was discovered, only Sedna, with a closest approach to the Sun of 76 AU, was known to stay significantly beyond this outer boundary for its entire orbit.
Both Sedna and 2012 VP113 were found near their closest approach to the sun, but they both have orbits that go out to hundreds of AU, at which point they would be too faint to discover. The similarity in the orbits found for Sedna, 2012 VP113 and a few other objects near the edge of the Kuiper Belt suggests the new object’s orbit might be influenced by the potential presence of a yet unseen planet perhaps up to 10 times the size of Earth. Further studies of this deep space arena will continue.

Figure 2: a) Orbit diagram for the outer solar system. The Sun and Terrestrial planets are at the center. The orbits of the four giant planet Jupiter, Saturn, Uranus and Neptune are shown by purple solid circles. The Kuiper Belt (including Pluto) is shown by the dotted light blue region just beyond the giant planets. Sedna’s orbit is shown in orange while 2012 VP113’s orbit is shown in red. Both objects are currently near their closest approach to the Sun (perihelion). They would be too faint to detect when in the outer parts of their orbits. Notice that both orbits have similar perihelion locations on the sky and both are far away from the giant planet and Kuiper Belt regions. b) Plot of all the known bodies in the outer solar system with their closest approach to the Sun (Perihelion) and eccentricity.
