Meteors are the product of leftover comet particles and bits from asteroids. When these objects come close to the sun, they leave a dusty trail in their wake. Every year, these particles collide ...

The heat from a star can evaporate a comet’s ice particles, liberating dust particles. Lighter particles form the comet’s tail while heavier ones fall back on to its surface, building a crust.

It has long been assumed that the gases of a comet tail are pushed away from the comet by the pressure of light from the sun. It now appears that many tails are caused by a wind of charged particles ...
