Gliese-1132b

Gliese 1132 b (also known as GJ 1132 b) is an exoplanet orbiting the red dwarf star Gliese 1132 40 light years (13 parsecs) from Earth, in the constellation Vela. The planet is considered uninhabitable but cool enough to possess an atmosphere.Chu, Jennifer (November 11, 2015). "New exoplanet in our neighborhood". MIT News. Retrieved 2015-11-12. Gliese 1132 b was discovered by the MEarth-South array in Chile.NASA Exoplanet Archive New ticker slide 1
It has been called "one of the most important planets ever discovered beyond the Solar System": Due to its relative proximity to Earth, telescopes should be able to determine the composition of its atmosphere, the speed of its winds and the color of its sunsets. This is due in part to the small diameter of its parent star (20% that of the Sun), which increases the effect on the star's light of its transits. The planet's diameter is approximately 20% larger than that of the Earth and its mass is estimated at 1.6 times that of Earth, implying that it has an Earth-like rocky composition. Gliese 1132 b orbits its star every 1.6 days at a distance of 1.4 million miles (2.24 million kilometres).
The planet receives 19 times more stellar radiation than Earth. The temperature of the top of its atmosphere is estimated at 500 °F (260 °C; 533 K). The planet is estimated to be hotter than Venus, as higher temperatures may prevail near the surface.
