A Comet is a mixture of ice and dust that, for some reason, has failed to become part of a planet.
Comets have highly eccentric orbits, which swing them close to the sun, then deep into space—far beyond Pluto.
As a Comet draws closer to the sun it begins to melt, leaving a plume of debris in its wake.
They were once believed to be bad omens. It is now understood that a Comet is a rare but harmless spectacle.
Well the round is over.
It's the end of the trip.
It's time to go home.
