And 'there might be more planets in the system.'🌌
A global team of astronomers discovered a new multiplanet system within our galactic neighborhood that is a relatively small 10 parsecs away — roughly 33 lightyears — from Earth.The system is made up of a cool M-dwarf star called HD 260655 that hosts at least two terrestrial Earth-sized planets, according to the astronomers who made the discovery.
They will present their discovery today, June 15, at the meeting of the American Astronomical Society in Pasadena, California. The astronomers estimated that, due to their short orbits, the planets are incredibly hot and uninhabitable on their surfaces. They estimated the inner planet to have a surface temperature of 710 kelvins and the outer planet to have a temperature of roughly 560 K . They also determined that the inner planet, called HD 260655b, orbits its star once every 2.8 Earth days and is approximately 1.2 times bigger than the Earth. The outer planet, dubbed HD 260655c, orbits once every 5.7 days and is 1.
