Astronomers find 85 possible planets which may be cool enough to sustain life

The 85 candidate exoplanets take between 20 and 700 days to orbit their host stars, whereas most exoplanets observed by TESS have orbital periods of 3-10 days

Astronomers have discovered 85 possible planets outside our solar system with temperatures potentially cool enough to sustain life.

These exoplanet candidates are similar in size to Jupiter, Saturn and Neptune, and were discovered using data from Nasa’s Transitioning Exoplanet Survey Satellite (TESS).
