Talk:Comet
From Kerbal Space Program Wiki
I suspect objects of size class F-I are comets, although only class H and I are "gargantuan". They have eccentric orbits and are named. No more comets seem to spawn when there are two comets in the game. You can disappear comets by stopping to track them. Class I comets usually are on a Kerbol escape trajectory. Class H comets have been seen on escape trajectories, too.
