Comet Hale–Bopp  

Comet Hale-Bopp is the biggest and brightest comet that has come by Earth in the last hundred years. It has a very large nucleus with a diameter estimated to be 40 to 80 kilometers. This enormous nucleus size is one the reasons behind its unusual brightness.

This comet was discovered by two astronomers independently, Alan Hale and Thomas Bopp on July 23, 1995. It is also known as the Great Comet of 1997. It became visible to the naked eye in May 1996 and remained visible till December 1997.
