December 30, 2012 – SPACE - A recently discovered comet that is rapidly approaching the Sun could outshine the Moon in 2013, researchers think. The comet may even be visible in daylight, as the Great Comet of 1680 was. It’s expected to be visible towards the end of the year, roughly from October to the following January. “The recently discovered object, known as comet ISON, is due to fly within 1.2 million miles (1.9 million km) from the center of the Sun on Nov. 28, 2013 said astronomer Donald Yeomans, head of NASA’s Near Earth Object Program at the Jet Propulsion Laboratory in Pasadena, Calif. As the comet approaches, heat from the Sun will vaporize ices in its body, creating what could be a spectacular tail that is visible in Earth’s night sky without telescopes or even binoculars from about October 2013 through January 2014.” With such a bright object in the night sky during the latter part of the year, it may somewhat drown out what will otherwise be a spectacular year of meteor showers in 2013. The comet will need to survive its approach to the Sun though, for that to happen. And it’s possible that the comet could disintegrate as it gets close to the Sun. Interestingly, comet ISON is following a very similar path to the famous comet of 1680, which was bright enough to be visible in the middle of the day. It is following such a similar orbit that researchers theorize that they may both originate from the same fragmented parent body. “Comet ISON could be the brightest comet seen in many generations – brighter even than the full moon,” wrote British astronomer David Whitehouse. “In 2013, Earth has two shots at a comet show. Comet Pan-STARRS is due to pass by the planet in March, eight months before ISON’s arrival. The last comet to dazzle Earth’s night-time skies was Comet Hale-Bopp, which visited in 1997. Comet 17P/Holmes made a brief appearance in 2007.” –Planet Save (excerpt)
