Is CD-35 2722 B b in the Habitable Zone?

The position of CD-35 2722 B b relative to the habitable zone of CD-35 2722 B cannot be precisely determined from the available orbital data.

Orbit and Year Length

A year on CD-35 2722 B b — one full orbit around CD-35 2722 B — lasts 171.1 Earth days, between the years of Mercury (88 days) and Earth (365 days). It orbits at an average distance of 0.200 AU — closer to its star than Mercury is to the Sun. Its orbit is mildly elliptical (eccentricity 0.27).

How Was CD-35 2722 B b Discovered?

CD-35 2722 B b was discovered in 2026 using the radial velocity method, with observations from Paranal Observatory.

The radial velocity method measures the subtle wobble of a star caused by the gravitational pull of an orbiting planet, visible as periodic shifts in the star's light spectrum. The size of the wobble reveals the planet's minimum mass.
