These three panels show the first detection of the faint distant object
dubbed "Sedna." Imaged on November 14th from 6:32 to 9:38 Universal Time,
Sedna was identified by the slight shift in position noted in these three
pictures taken at different times. Subsequent observations at longer time
intervals provided the information necessary to deduce the nature of
Sedna's 10,500 year orbit around the Sun. The field of view of each
frame is 3.4 arcminutes square, and each pixel is 1.0 arcsecond.
