PSR B1620-26 b
PSR B1620-26 b is a cold gas giant orbiting PSR B1620-26 in the constellation Scorpius. It was discovered in 2003 using the pulsar timing method.
Is PSR B1620-26 b in the Habitable Zone?
The position of PSR B1620-26 b relative to the habitable zone of PSR B1620-26 cannot be precisely determined from the available orbital data.
Orbit and Year Length
PSR B1620-26 b orbits at an average distance of 23.000 AU.
How Was PSR B1620-26 b Discovered?
PSR B1620-26 b was discovered in 2003 using the pulsar timing method, with observations from Hubble Space Telescope.
Pulsar timing detects planets around pulsars — rapidly spinning stellar remnants that emit radio pulses with clock-like precision. An orbiting planet makes the pulses arrive slightly early or late in a repeating pattern.
The Host Star: PSR B1620-26
