As astronomers add to their known population of distant planets — called exoplanets — they expand their understanding of how Earth’s rocky cousins ​​appear around other stars. And their research often stumbles upon strange orbs, like one newly discovered planet covered in molten magma with a “year” that lasts only half a day.

The discovery, named TOI-1075 b, was spotted in observations by NASA’s Transiting Exoplanet Survey Satellite (TESS) spacecraft. Data from these four yearsthe old mission revealed that TOI-1075 b has a superheated surface of about 1,922 degrees Fahrenheit (1,050 Celsius). These extreme conditions are caused by the planet’s proximity to its parent star, a small red-orange star about 200 light-years away. Earth. But aside from the planet’s scorching climate and ultra-short orbit — taking just 14.5 hours — it’s fascinating for another big reason: TOI-1075 b is one of the most massive exoplanet class.
