Dark comets
What is a comet?
Traditionally, the difference between comets and asteroids is that comets have beautiful cometary tails. These tails form because comets have ice in them, while asteroids supposedly do not.
What is a nongravitational acceleration?
These dark comets have nongravitational accelerations like comets, so they experience a rocketlike recoil from comet outgassing. However, they don't have the dusty tails that most comets have.
Dark comets!!
