Osiris is an extrasolar planet that orbits the Sun-like star HD 209458 in the constellation Pegasus, some 150 light years from Earth's solar system. HD209458 is a 7th magnitude star, visible on Earth with binoculars. The radius of its orbit is only 7 million kilometers, resulting in a year only 3.5 Earth days long and an estimated surface temperature of about 1000°C.Photo credit: NASA/ESA/CNRS
