claim: ( Kerr 2007 ) points out that the sunlight-reflecting haze that cools much of the planet seems to have thinned over the past decade or so.
evidence: Before the arrival of Voyager 1 in 1980, Titan was thought to be slightly larger than Ganymede ( diameter 5,262 kilometers ( 3,270 mi ) ) and thus the largest moon in the Solar System; this was an overestimation caused by Titan's dense, opaque atmosphere, with a haze layer 100-200 kilometres above its surface.
