PSR B0329+54 b
PSR B0329+54 b is a terrestrial planet orbiting PSR B0329+54 in the constellation Camelopardalis. It lies about 1,647 light-years from Earth and was discovered in 2017 using the pulsar timing method.
Is PSR B0329+54 b in the Habitable Zone?
The position of PSR B0329+54 b relative to the habitable zone of PSR B0329+54 cannot be precisely determined from the available orbital data.
Orbit and Year Length
A year on PSR B0329+54 b — one full orbit around PSR B0329+54 — lasts 10,140.0 Earth days, longer than Jupiter's 12-year orbit. It orbits at an average distance of 10.260 AU. Its orbit is mildly elliptical (eccentricity 0.24).
How Was PSR B0329+54 b Discovered?
PSR B0329+54 b was discovered in 2017 using the pulsar timing method, with observations from Multiple Facilities.
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.
How Far Away Is PSR B0329+54 b?
PSR B0329+54 b is 1,646.9 light-years (504.9 parsecs) from Earth. Light arriving here tonight left the planet about 1,647 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 28,985,440 years to make the journey.
