The Watchers – Is Comet ISON just an ordinary comet?

May 6, 2013

Well, if you ask the question from the title, most people who are even remotely interested in astronomy and comets will most likely answer – NO – Comet ISON ( Comet C/2012 S1) is not an ordinary comet! In fact, it is a very interesting comet with plenty of potential for both experts and millions of stargazers around the globe.

As of May 2, Comet ISON was approximately 3.885 AU from the Sun, which is about 581 million kilometers (361 million miles) distant from the Sun. Ernesto Guido and Nick Howes of the Remanzacco Observatory used the 2-meter Ritchey-Chretien Liverpool Telescope to identify almost the same tail structure which was seen in the Hubble Space Telescope images of this comet from April 10, 2013. Their initial approximation of the tail length is around 28 arcseconds, which is bigger than some recent reports from smaller telescopes.
