Random information on the term “COMA”:

The coma is the nebulous envelope around the nucleus of a comet, formed when the comet passes close to the Sun on its highly elliptical orbit; as the comet warms, parts of it sublime.[1] This gives a comet a “fuzzy” appearance when viewed in telescopes and distinguishes it from stars. The word coma comes from the Greek “kome” (κόμη), which means “hair” and is the origin of the word comet itself.[2][3]

The coma is generally made of ice and comet dust.[1] Water dominates up to 90% of the volatiles that outflow from the nucleus when the comet is within 3-4 AU of the Sun.[1] The H2O parent molecule is destroyed primarily through photodissociation and to a much smaller extent photoionization.[1] The solar wind plays a minor role in the destruction of water compared to photochemistry.[1] Larger dust particles are left along the comet’s orbital path while smaller particles are pushed away from the Sun into the comet’s tail by light pressure.
