All attributes below are measured relative to the Earth: Of the other objects, Ganymede has the largest mass (0.02). Note: Although 2003 UB313 is a minor planet, it is being considered as possibly being a major planet (the tenth in the solar system). For a more comprehensive table, see table of planets in the solar system. ...

The object currently has the provisional designation 2003 UB313, granted automatically according to the IAU's naming protocols for minor planets. The next step in the object's identification will be the external verification of its orbit and assignment of a permanent designation number. Should 2003 UB313 be treated as any other minor planet, its discoverers will then have the exclusive right to propose a name during a ten year window that begins with its permanent numbering, subject to the approval of the Committee on S ...

2003 UB313 is classified as a scattered disk object (SDO), a category of TNO which are believed to have been "scattered" from the Kuiper belt and into more distant and unusual orbits following gravitational interactions with Neptune as the solar system was forming. Although its high orbital inclination is unusual among the current known SDOs, theoretical models suggest that objects which were originally near the inner edge of the Kuiper belt are scattered into orbits with higher inclinations than objects from the outer belt. Inner ...

In 1999, the winter-over physician, Dr. Jerri Nielsen discovered she had breast cancer. She had to rely on self-administered chemotherapy using supplies from a daring July cargo drop, then was picked up in an equally dangerous mid-October landing. The station has featured prominently in several science fiction television series, including The X-Files movie Fight the Future and the Stargate Atlantis series premiere "Rising". A South Pole station called Snowcap Base was the site of the first Cybermen invasion ...

Authors have created thousands of fictional planets. Most of them are nearly indistinguishable from Earth, which is why Brian M. Stableford calls them "Earth-Clones". In these, differences with Earth life are mostly social (like Barrayar in the science fiction of Lois McMaster Bujold). More physically unusual planets have been depicted in hard science fiction books. For the Star Trek universe, a detailed planetary classification system has been devised.

The total surface area of the solar system's objects that have solid surfaces and a diameter greater than 1 km is ~1.7×109 km2 —about 11 times the area of the Earth's land masses. It has been suggested that the Sun may be part of a binary star system, with a distant companion named Nemesis. Nemesis was proposed to explain some timing regularities of the great extinctions of life on Earth. The hypothesis says that Nemesis creates periodical perturbations in the Oort cloud of comets surrounding the solar system, ...

2003 UB313 has an orbital period of 557 years, and currently lies at almost its maximum possible distance from the Sun (aphelion). It is currently the most distant known solar system object from the Sun at a distance of 97 astronomical units, although about forty known TNOs (most notably 2000 OO67 and Sedna), while currently closer to the Sun than 2003 UB313, have greater

2003 UB313 was discovered by the team of Michael Brown, Chad Trujillo, and David Rabinowitz on January 5, 2005 from images taken on October 21, 2003, and the discovery was announced on July 29, 2005, the same day as two other large TNOs, 2003 EL61 and 2005 FY9. The search team has been systematically scanning for large outer solar system bodies for several years, and had previously been involved in the discovery of several other very large trans-Neptunian objects, including 500 ...
