places off-planet #2 – three comets
In my life so far, I have seen three major comets – Halley’s Comet in 1986, Hyakutake in 1996, and Hale-Bopp in 1997. There have been comets since then, I know, but I have always been asleep!
A comet is composed of a ‘nucleus’ of rock, dust and frozen gas, and a tail. The tail is formed when the gasses in the nucleus are heated by the sun and create an atmosphere or ‘coma’. The sun’s radiation and the solar wind cause the coma to flow away from the sun as a tail. Since the comet can be moving away from the sun, sometimes this means the comet moves in the direction of its tail!
How many comets have you seen?
