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.
