Hale-Bopp. Artwork of the comet Hale-Bopp above an ocean shore. Hale-Bopp was one of the brightest comets of the 20th century,and was seen for much of early 1997. A comet is a lump of ice and rock. Its tail is formed as its ice evaporates as it nears the Sun. The tail always points away from the Sun,and may stretch for millions of kilometres | |
