About the Object
- R.A. PositionR.A. PositionRight ascension – analogous to longitude – is one component of an object's position.03h 13m 51.12s
- Dec. PositionDec. PositionDeclination – analogous to latitude – is one component of an object's position.05° 45' 41.14"
- DistanceDistanceThe 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.Approximately 13.5 billion kilometers (8.4 billion miles)

This is the clearest-ever view of the farthest object yet discovered in the solar system. The object is unofficially named "Sedna" (after an Inuit goddess of the sea). [Lower right] At a distance of over 8 billion miles, Sedna is so far away it is reduced to one picture element...
