The nearest star to our sun, Proxima Centauri, may host a second planet

#1

Post by Makuser »

Astronomers have discovered what appears to be a second exoplanet in orbit around the nearest star to our sun, Proxima Centauri, as reported by Universe Today. The planet candidate is called Proxima c, its mass is around half that of Neptune, and it orbits its star at a distance 1.5 times greater than the distance between the Earth and the sun. Due both to this distance and the fact the star is relatively cool, the planet would likely be very cold. If it does not have an atmosphere to keep it warm, its surface temperature could be below -200°C (-328°F). You can read the entire article here, at:
