Two New Rocky Planets Discovered Close to the Solar System

TESS has once more found success. Two additional super-Earths have been discovered orbiting a star only 33 light-years away by NASA's planet-hunting probe.

These two rocky planets are among the nearest ones ever discovered.

Its designation is HD 260655. It's a brilliant M dwarf star that's also referred to as a red dwarf.

Despite the name "Earth" being suggestive, none of these rocky super-Earths is expected to harbor life due to their extremely high temperatures.

However, scientists continue to believe that they merit additional observation.

The discovery was made public in a brand-new study with the title "The HD 260655 system: Two rocky worlds transiting a brilliant M dwarf at 10 PC."

Rafael Luque of the University of Chicago and the Institute of Astrophysics in Andalusia, Spain is the principal author.

The research will be published in the journal Astronomy and Astrophysics, but it is presently accessible online at the pre-press website arxiv.org.

With an orbital period of 2.7 days, HD 260655b is the object closest to the star. Its mass is 2.14 Earth masses, and its radius is 1.2 Earth radii.

The orbital period of HD 260655c is 5.7 days. Its mass is 3.09 Earth masses, and its radius is 1.5 Earth radii.
