A NASA satellite launched in December to scan the universe for objects near and far is proving its worth, turning up objects in the inner solar system. Over the course of its 10-month mission, the Wide-field Infrared Survey Explorer (WISE) spacecraft will survey the skies in the infrared, a wavelength band optimal for spying on distant, dust-shrouded galaxies and for spotting nearby objects that are cool and dim, such as comets and failed stars known as brown dwarfs. (Even cool objects give off heat, which is visible in the infrared.) Read more
NASA's Wide-field Infrared Survey Explorer, or WISE, has discovered its first comet, one of many the mission is expected to find among millions of other objects during its ongoing survey of the whole sky in infrared light. Officially named "P/2010 B2 (WISE)," but known simply as WISE, the comet is a dusty mass of ice more than 2 kilometres in diameter. It probably formed around the same time as our solar system, about 4.5 billion years ago. Comet WISE started out in the cold, dark reaches of our solar system, but after a long history of getting knocked around by the gravitational forces of Jupiter, it settled into an orbit much closer to the sun. Right now, the comet is heading away from the sun and is about 175 million kilometres from Earth. Read more
The WISE (Wide-field Infrared Survey Explorer) satellite discovered comet P/2010 B2 (WISE) on the 22nd January, 2010.
The preliminary orbital elements of the comet indicate a perihelion passage on the 20th December, 2009, at a distance of approximately 1.6 AU from the Sun and an orbital period of 5.18 years.
