Comet McNaught (2007, pictures www.spaceweather.com)

Comets are known as `hairy stars’. They are masses of dust and gas with a head and a huge gaseous tail that circle the sun in long orbits. Some return over a period – such as Halley’s comet. They only move at stellar-like speeds, and so unless one is totally un-initiated are not likely to be mistaken for an UAP.
