GJ 900 b
GJ 900 b is a cold gas giant orbiting the K7 star GJ 900 A in the constellation Pisces. It lies about 68 light-years from Earth and was discovered in 2024 using the imaging method.
Is GJ 900 b in the Habitable Zone?
The position of GJ 900 b relative to the habitable zone of GJ 900 A cannot be precisely determined from the available orbital data.
Orbit and Year Length
GJ 900 b orbits at an average distance of 12,000.000 AU.
How Was GJ 900 b Discovered?
GJ 900 b was discovered in 2024 using the imaging method, with observations from Multiple Observatories.
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 GJ 900 b?
GJ 900 b is 67.9 light-years (20.8 parsecs) from Earth. Light arriving here tonight left the planet around the year 1959. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 1,195,040 years to make the journey.
