Astronomers discover a quartet of teenage alien planets far, far away

3 min read

Astronomers have discovered a quartet of teenage exoplanets, according to data from NASA’s TESS mission.

The planets in question lie a bit over 130 light-years away from Earth. They orbit a pair of little orange dwarf stars, each smaller than the sun, named TOI 2076 and TOI 1808.  (TOI is short for TESS Object of Interest.)  Even though the two stars are not close — they’re a whole 30 light-years apart, actually — they’re moving in the same direction, and are both around the same age, suggesting that they formed in the same place.
