C/2012 K1 (PANSTARRS) is a comet discovered 8.7 AU from the Sun on 19 May 2012 using the Pan-STARRS telescope located near the summit of Haleakala-, on the island of Maui in Hawaii (U.S.).[1]
The comet starts 2014 as a northern hemisphere object. By late April 2014 it is expected to have brightened to roughly apparent magnitude ~9[4] making it a small telescope/binoculars target for experienced observers. The comet will come to perihelion (closest approach to the Sun) on 27 August 2014 at a distance of 1.05 AU (157,000,000 km; 98,000,000 mi) from the Sun.[1] It crosses the celestial equator on 15 September 2014 becoming a southern hemisphere object. The comet should reach it's peak magnitude of ~6 in mid-October 2014[5] when it will have an elongation of around 75 degrees from the Sun. It may be visible to the naked eye, but will be much easier to detect in binoculars. |
