[[File:G1758.jpg|thumb|280px|The Japanese "Subaru" telescope in Aug. 2009 took one of the first photos of an exoplanet. Point "B" is an exoplanet and probably so is C. "B" (formally GJ758 B) has a mass of 10 to 40 times Jupiter, and is either a giant planet or a lightweight brown dwarf; its temperature is about 620oF / 327oC]]
