VHS J125601.92-125723.9 b
VHS J125601.92-125723.9 b is a hot Jupiter orbiting VHS J125601.92-125723.9 in the constellation Corvus. It was discovered in 2015 using the imaging method.
How Big Is VHS J125601.92-125723.9 b?
VHS J125601.92-125723.9 b has a radius of 13.67 times that of Earth, or 1.22 times the radius of Jupiter. Its mass is 5,085 times that of Earth.
Is VHS J125601.92-125723.9 b in the Habitable Zone?
The position of VHS J125601.92-125723.9 b relative to the habitable zone of VHS J125601.92-125723.9 cannot be precisely determined from the available orbital data.
Temperature on VHS J125601.92-125723.9 b
The equilibrium temperature of VHS J125601.92-125723.9 b is about 1,194 K (921 °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
A year on VHS J125601.92-125723.9 b — one full orbit around VHS J125601.92-125723.9 — lasts 5,800,000.0 Earth days, longer than Jupiter's 12-year orbit. It orbits at an average distance of 350.000 AU. Its orbit is highly elliptical (eccentricity 0.68), swinging dramatically closer to and farther from its star.
How Was VHS J125601.92-125723.9 b Discovered?
VHS J125601.92-125723.9 b was discovered in 2015 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.
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. VHS J125601.92-125723.9 b scores 0.07, ranking #5,043 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.
