LP 261-75 b
LP 261-75 b is a exoplanet orbiting the M4.5 V star LP 261-75 A in the constellation Leo Minor. It lies about 111 light-years from Earth and was discovered in 2006 using the imaging method.
Is LP 261-75 b in the Habitable Zone?
The position of LP 261-75 b relative to the habitable zone of LP 261-75 A cannot be precisely determined from the available orbital data.
Temperature on LP 261-75 b
The equilibrium temperature of LP 261-75 b is about 1,500 K (1,227 °C) — hot enough to melt many metals. This estimate ignores any atmosphere, which could change surface temperatures dramatically — Earth's greenhouse effect adds about 33 °C.
Orbit and Year Length
LP 261-75 b orbits at an average distance of 450.000 AU.
How Was LP 261-75 b Discovered?
LP 261-75 b was discovered in 2006 using the imaging method, with observations from Apache Point Observatory.
Direct imaging captures actual pictures of a planet by blocking out the overwhelming glare of its host star. It works best for young, hot, massive planets on wide orbits.
How Far Away Is LP 261-75 b?
LP 261-75 b is 110.7 light-years (33.9 parsecs) from Earth. Light arriving here tonight left the planet around the year 1916. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 1,948,320 years to make the journey.
