Revision as of 23:39, 15 January 2012
The XO Telescope is a telescope located on the 3,054 m summit of Haleakala on Maui, Hawaii, formed by a pair of 200 mm telephoto lenses. It is used by the XO Project to detect extrasolar planets using the transit method. It is similar to the TrES survey telescope. The construction of the one-of-a-kind telescope cost $60,000 for the hardware, and much more than that for the associated software.
Planets discovered
The XO telescope has discovered five objects so far, four are hot Jupiter planets and one, XO-3b, is probably a brown dwarf. All were discovered using the transit method.
