Comet ISON

Comet ISON will make an appearance in Earth's sky in 2013. While it's hard to predict just how bright the comet will be when it arrives, some astronomers are saying that it could be as bright as the full moon or perhaps, even visible in daylight.

The comet is named after a telescope for the International Scientific Optical Network. Two Russians spotted ISON through a 15.7-inch (0.4-meter) reflecting telescope from that organization.

ISON is considered a "sungrazer," meaning that it will pass very close to the sun when it gets into the inner solar system in November 2013.
