2007 OR10, the largest unnamed body in the solar system, was visible during the K2 mission’s campaign three for 19 days in late 2014.
K2 is the new mission of Kepler spacecraft. The apparent movement of the faint dwarf planet (indicated with the arrow) among the stars is caused by the changing position of Kepler as it orbits around the sun.
The diffuse light sweeping across is a reflection from the much brighter planet Mars passing nearby.
