Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. (84522) 2002 TC302 is a large, red 2:5 resonant trans-Neptunian object discovered on October 9, 2002, by Mike Brown's team at the Palomar Observatory. It is very likely a dwarf planet. 2002 TC302 has an absolute magnitude of 3.8, and the Spitzer Space Telescope has estimated it to have a diameter of 1145.7±325 km. This qualifies it as one of the largest dwarf-planet candidates. The red spectra suggests that 2002 TC302 has very little fresh ice on its surface and may…mehr

It is very likely a dwarf planet. 2002 TC302 has an absolute magnitude of 3.8, and the Spitzer Space Telescope has estimated it to have a diameter of 1145.7±325 km. This qualifies it as one of the largest dwarf-planet candidates. The red spectra suggests that 2002 TC302 has very little fresh ice on its surface and may explain why it has a lower-than-average estimated albedo of ~0.03. For example, 2002 AW197 has a higher estimated albedo, resulting in a brighter absolute magnitude, and is estimated to be physically smaller.
