Comet Hale-Bopp on March 16, 1997: The brightest comet that most people alive today can remember is Comet Hale-Bopp, which hung in our evening sky like a kite for several weeks in spring 1997. In 2013, two new comets might outperform Hale-Bopp — Comet PanSTARRS and Comet ISON. Comet ISON, in particular, has the potential to outshine Hale-Bopp by a factor of 4000, becoming one of the brightest comets seen from Earth in centuries. We’ll just have to wait and see.

Nov. 29, Friday, 12:00, Comet ISON at Perihelion, possibly visible near sun in daytime sky (0.0125 AU from sun)*
