This phenomenon and news had been circulating since yesterday and for sure many have already ready their camera and prepare for stargazing. However, pardon us to cut your excitement short since this phenomena is a hoax. There is no such thing as two moons in 2010.
Below are the facts regarding this event according to Urban Legends:
Seven years ago, on August 27, 2003, the oscillating orbits of Mars and Earth did, in fact, bring the two planets closer together than at any other time during the past 50,000 years. And though Mars never actually appeared "as large as the full moon to the naked eye" — not even close — it was indeed, for a few special days in 2003, among the brightest objects in the night sky.
October 2005 brought another well-publicized "close encounter," though in that case Earth and Mars were about 13 million kilometers further apart than during the 2003 event.
Nothing so spectacular is predicted for 2010.
