Two Young Planetary Systems Detected

Astronomers, using NASA’s Transiting Exoplanet Survey Satellite (TESS) have discovered two new young planetary systems.

TOI-251 and TOI-942

TOI-251 and TOI-942 are the new young planetary systems detected by TESS. Astronomers have found that these two stars are not older than 320 million years. They are orbited by a mini-Neptune planet and two Neptune-sized exoplanets. The finding is reported in a paper published on the website “” of Cornell University on November 26th.

“TOI-251 and TOI-942 are two field stars exhibiting photometric and spectroscopic signatures of youth, hosting transiting Neptune that were identified by TESS observations”, the astronomers wrote in the paper.

TOI-251 is at a distance of about 324 light years away and a G-Type star about the mass of the sun with a radius of approximately 0.88 solar radii.

TOI-942 is at a distance of about 498 light years away from earth and a K-Type star. This is about the size of sun but 21% less massive.
