Kometes – “star with a tail”, “comet”, “shaggy”; literally – “long-haired”), small bodies of the solar system, rotating around the sun in elongated orbits and looking like foggy objects usually with a light clot – core in the center and tail. When approaching the Sun, the tail of the comet increases, formed by gases evaporating under the solar heat.

Comet Hale-Bopp 1996
Presumably, long-period comets fly to us from the Oort Cloud, located on the outer borders of the solar system, in which millions of cometary nuclei circulate.

Comets are shapeless lumps measuring just a few kilometers, consisting of ice mixed with dust particles. Comets move in very elongated orbits, being mostly far from the Sun, where they remain invisible, and Continue reading
