Using the data obtained from NASA's Kepler space telescope to measure the orbits of distant planets, scientists discovered the planet EPIC 228813918 b outside the solar system with a faster rotation speed. many times than the Earth.
EPIC 228813918 b revolves around an M-type dwarf named EPIC 228813918 and has time to complete an orbit of less than 4.5 hours, one day on Earth will be equivalent to more than 5 years on the planet. Therefore, if people move to live on this planet will live up to 150,000 years.
However, scientists for the EPIC 228813918 b move too close to its mother, causing the planet to have too strong radiation, which could affect life here. At that time, if you still keep the normal lifestyle as in Earth, people will sleep for up to 2 years each time they put their backs. Therefore, the 150,000 year mark will pass very quickly.
According to scientists, EPIC 228813918 b is roughly the size of the Earth and it is estimated that the planet has 45% iron in its composition.
EPIC 228813918 b is not the shortest orbit planet ever discovered. Previously, astronomers used to discover planet KOI 1843.03, turning around M-type dwarfs with time faster than 4 minutes. It is about the same size and has a lot of iron.
