Late in 2012, astronomers discovered a distant sungrazing comet that got many people very excited. Around the time of its perihelion – or closest approach to the sun – on November 28, 2013, Comet C/2012 S1 (ISON) has the potential to become a striking object visible to the eye alone. Will Comet ISON become a legendary comet of the century? It might. But it might not. Comet ISON will come within 800,000 miles (1.2 million km) of our sun’s surface on November 28. That’s over 100 times closer to the sun than Earth. This close pass to the sun might cause Comet ISON to break to pieces, and, if that happens, the comet might fizzle. Or ISON might emerge from perihelion bright enough to see easily with the eye, with a long comet tail that stretches across a quarter of the sky. Comets are notoriously unpredictable. Still, this comet is one you’ll want to watch.
