This is an artist's impression of the icy Kuiper belt object 2002 LM60, dubbed "Quaoar" by its discoverers. With the help of NASA's Hubble Space Telescope, astronomers have determined that Quaoar (pronounced kwa-whar) is the largest body found in the solar system since the discovery of Pluto 72 years ago. Quaoar is about 800 miles (1300 kilometers) in diameter and is about half the size of Pluto. Like Pluto, Quaoar dwells in the Kuiper belt, an icy debris field of comet-like bodies extending 7 billion miles beyond Neptune's orbit. Quaoar is the farthest object in the solar system ever to be resolved by a telescope. It is about 4 billion miles (6.5 billion kilometers) from Earth, more than 1 billion miles farther than Pluto.

| About The Object | |
|---|---|
| Object Name | A name or catalog number that astronomers use to identify an astronomical object. |
| Object Description | The type of astronomical object. |
| R.A. Position | Right ascension – analogous to longitude – is one component of an object's position. |
| Dec. Position | Declination – analogous to latitude – is one component of an object's position. |
| Constellation | One of 88 recognized regions of the celestial sphere in which the object appears. |
| Distance | The physical distance from Earth to the astronomical object. Distances within our solar system are usually measured in Astronomical Units (AU). Distances between stars are usually measured in light-years. Interstellar distances can also be measured in parsecs. |
| Dimensions | The physical size of the object or the apparent angle it subtends on the sky. |
