They discover the smallest known star, only 7 times larger than Earth. It is a hot subdwarf about 2,760 light years from Earth.
Experts named the star TMTS J0526B and assured that the star has a mass one-third the size of our sun and that it burns helium at 2,225 degrees Celsius. According to the study, the star and its companion,. which is too faint to be observed directly, orbit each other every 20 minutes. For the research, the Tsinghua-Ma Huateng Telescope had obtained photometric data of more than 27 million stars.
