The Meteor And The Comet

How different are these two streaks? The streak on the upper right is Comet Tsuchinshan-Atlas showing an
impressive dust tail. The comet is a large and dirty iceberg that entered the inner Solar System and is shedding gas and dust as it is warmed by the Sun’s light. The streak on the lower left is a meteor showing an impressive
evaporation trail. The meteor is a small and cold rock that entered the Earth’s atmosphere and is shedding gas and dust as it is warmed by molecular collisions. The meteor was likely once part of a comet or asteroid — perhaps later composing part of its tail. The meteor was gone in a flash and was only caught by coincidence during a
series of exposures documenting the comet’s long tail. The featured image was captured just over a month ago from Sichuan Province in China.
