Gliese 536 b also known as GJ 536 b^[2][1][3] is a nearby^[5][6] Super-Earth sized exoplanet orbiting interior to the circumstellar habitable zone^[5][6] of the red dwarf (M1)^[1] star Gliese 536 every 8.7 days. Due to its short orbital period it could help with future studies of biological activity on exoplanets.^[5]

This exoplanet is given the title Super-Earth due to its immense size which is more than five times greater than the Earth. Like many other rocky exoplanets, Gliese 536 b should be part of a large planetary group. Astronomers are still in search of other planets that are in orbit of star Gliese 536.^[7] But this planet is hotter than Venus, and although the planet is hotter than it, it may be similar to Venus.
