2MASSI J0937347 293142

2MASS J09373487 2931409 is a T6 dwarf in the constellation Leo. It has an unusual spectrum suggests a metal-poor atmosphere and / or a high surface acceleration ( high pressure at the surface). By measuring the parallax in the infrared, his removal was determined to be about 20 light years. Its effective temperature is estimated to be about 800 Kelvin.
