The comet is known as C/2012 S1 and it is coming close to Earth next year. When it was first sighted in September, it was 625 million miles away from earth. A little over a year from now, on November 28, 2013, the comet will come within 800,000 miles from the Sun's surface, which could make it bright enough to be visible for a short time in the middle of the day!
Scientists believe that this comet might even be the same as one sighted in the year 1680, which also put a dazzling show. Scientists say that on November 28th of next year, the comet will whirl rapidly around the Sun in a hairpin-like curve and become extremely bright. Then, it will be visible in the evening sky after sunset and in the morning sky before sunrise. Here's hoping we get a good show!
