Astronomical telescope on the summit of Haleakala on the island of MauiThe XO Telescope is an astronomical telescope located on the 3,054 m (10,000 foot) summit of Haleakala on Maui, Hawaii. It consists of two 200-millimeter telephoto camera lenses, and resembles binoculars in shape. 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 six objects so far, five are hot Jupiter planets and one, XO-3b, may be a brown dwarf. All were discovered using the transit method.
Light green rows indicate that the planet orbits one of the stars in a binary star system.
