Planet 10-b is 20 times closer to its star than the distance Merkury planet to the sun in the Milky Way.

Density of the planet is 4.5 times thicker and 1.4 times larger than the planet Earth.

According to the calculations of astronomers 10-b is very hot and the temperature of 1500 degrees Celsius.

An astronomer who worked at the Center for Aeronautical and Space Agency (NASA) in Washington, Douglas Hudgins said that they found a nearly equal-sized planet earth.

He also emphasized that their discovery is a stepping stone to finding a new planet that can be occupied.
