Spitzer的失误，最终结果八月底见分晓

"10th Planet" Bigger than Thought?

Due to a Spitzer Space Telescope pointing error, the infrared observatory
didn't actually observe 2003 UB313 as had been previously reported.
Astronomers had used the "nondetection" to establish an upper size limit
on the largest known Kuiper Belt object. If Spitzer sees the body in
follow-up observations scheduled for late August, it could mean that 2003
UB313 is much larger than the original limit of around 3,400 kilometers
(2,100 miles). Hubble Space Telescope observations are also in the works.
