Gliese 536

Gliese 536 is a red dwarf star in the constellation Virgo. It lies at a distance of approximately 34 light-years and has two known exoplanets.

Planetary system

The two known exoplanets orbiting 536 were found from Doppler spectroscopy. Gliese 536 b was discovered in 2017, while Gliese 536 c was discovered in 2025. Based on their minimum masses of and, both are thought to be either super-Earths or mini-Neptunes. The host star rotates at an angle of ° relative to Earth, and based on the assumption that the planets share this angle, their masses would be and. For an inclination less than 5°, both would be gas giants.
The habitable zone spans from 0.176 to 0.372 astronomical units, so planet c is orbiting just below this zone. The equilibrium temperatures of Gliese 536 b and c are and.
