Aftermath of Distant Planetary Collision? 97

gazurtoid writes "Astrobiology Magazine is reporting that astronomers have announced a mystery object orbiting the 8-million-year-old brown dwarf 2M1207 170 light-years from Earth might have formed from the collision and merger of two protoplanets. The object, known as 2M1207B, has puzzled astronomers since its discovery because it seems to fall outside the spectrum of physical possibility. Its combination of temperature, luminosity, and age do not match up with any theory. 'Hot, post-collision planets might be a whole new class of objects we will see with the Giant Magellan Telescope', said Eric Mamajek of the Harvard-Smithsonian Center for Astrophysics."
