HD 95086 b
HD 95086 b is a cold gas giant orbiting HD 95086 in the constellation Carina. It lies about 281 light-years from Earth and was discovered in 2013 using the imaging method.
Is HD 95086 b in the Habitable Zone?
The position of HD 95086 b relative to the habitable zone of HD 95086 cannot be precisely determined from the available orbital data.
Temperature on HD 95086 b
The equilibrium temperature of HD 95086 b is about 1,000 K (727 °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
HD 95086 b orbits at an average distance of 55.700 AU.
How Was HD 95086 b Discovered?
HD 95086 b was discovered in 2013 using the imaging method, with observations from Paranal 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 HD 95086 b?
HD 95086 b is 281.2 light-years (86.2 parsecs) from Earth. Light arriving here tonight left the planet around the year 1745. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 4,949,120 years to make the journey.
Earth Similarity Index
The Earth Similarity Index (ESI) scores how physically similar a planet is to Earth, from 0 to 1, based on radius, density, escape velocity and surface temperature. HD 95086 b scores 0.07, ranking #4,905 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.
