NASA’s Transiting Exoplanet Survey Satellite (TESS) has discovered three new planets, all of which orbit the same star.

The star they orbit is smaller and cooler than the sun.

2 of the planets are believed to be similar to Neptune at 260 degrees Fahrenheit, but one is considered potentially habitable.

Right now, it’s called GJ 357 d and is also being referred to as a super Earth.

“This is exciting, as this is humanity’s first nearby super-Earth that could harbor life – uncovered with help from TESS, our small, mighty mission with a huge reach,” said Cornell’s Lisa Kaltenegger, associate professor of astronomy, director of Cornell’s Carl Sagan Institute and a member of the TESS science team.

It’s about 31 light-years away.

And much hotter than earth, at about 150 degrees Fahrenheit.

“If GJ 357 d were to show signs of life, it would be at the top of everyone’s travel list – and we could answer a 1,000-year-old question on whether we are alone in the cosmos,” Kaltenegger said.
