"Findings such as this planet are the coldest object ever photographed directly from the outer solar system. Usually, we only found a very small star that has a temperature similar to Earth's atmosphere, "said Professor Astronomer Kevin Luhman as reported by UPI on Monday (31/10/2011).
He also added that the planet is like brown dwarf-sized planets moving through space, the star together with white dwarf stars who have Earth-cold temperatures.
"Basically, what we have found is a very small star with a cool temperature of the atmosphere such as Earth," he said.
Luhman said the formation of brown dwarf stars, like a giant cloud of dust and gas. However, because not enough mass to ignite thermonuclear reactions in its core, then there was a failed star who is very cool.
