G 196-3 b
G 196-3 b is a exoplanet orbiting G 196-3 in the constellation Ursa Major. It lies about 71 light-years from Earth and was discovered in 2024 using the imaging method.
Is G 196-3 b in the Habitable Zone?
The position of G 196-3 b relative to the habitable zone of G 196-3 cannot be precisely determined from the available orbital data.
Temperature on G 196-3 b
The equilibrium temperature of G 196-3 b is about 1,670 K (1,397 °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
G 196-3 b orbits at an average distance of 350.000 AU.
How Was G 196-3 b Discovered?
G 196-3 b was discovered in 2024 using the imaging method, with observations from European Space Agency (ESA) Gaia Satellite.
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 G 196-3 b?
G 196-3 b is 71.1 light-years (21.8 parsecs) from Earth. Light arriving here tonight left the planet around the year 1955. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 1,251,360 years to make the journey.
