Astronomers have discovered a new, incredibly small planet orbiting a nearby star Gliese 238

Star system: Gliese 238 | Distance from the Sun: 49.6 light years

The star Gliese 238 is only 50 light years away, which makes it one of the closest stars with known exoplanet. Newly discovered object is similar in size to Mars, but it orbits too close and there are temperatures close to 500 °C on its surface.
