Astronomers led by Giuseppe Conzo have discovered a super-Earth, Ross 318 b, orbiting the red dwarf star Ross 318, located 28 light-years away. With a mass 6.21 times that of Earth and a radius 1.74 times larger, it may possess a substantial atmosphere and lies within the habitable zone, making it a key target for future studies on extraterrestrial life.
- 01Ross 318 b is located just 0.16 AU from its host star, Ross 318.
- 02The exoplanet has a mass approximately 6.21 times that of Earth.
- 03Its radius is about 1.74 times that of Earth, indicating a potentially significant atmosphere.
- 04The star Ross 318 is a red dwarf, situated 28 light-years from Earth, with a high magnetic activity.
- 05This discovery could aid in the search for signs of life beyond our planet.

A team of astronomers, led by Giuseppe Conzo from the Gruppo Astrofili Palidoro (GAP), has discovered a new exoplanet named Ross 318 b orbiting the red dwarf star Ross 318, located just 28 light-years from Earth. This discovery was made using data from the Carmenes spectrograph, the High Resolution Echelle Spectrometer (HIRES), and the TESS satellite. Ross 318 b is situated only 0.16 AU from its star and has a mass about 6.21 times that of Earth, along with a radius approximately 1.74 times larger. These characteristics suggest that the exoplanet may possess a substantial atmosphere and lies within the star's conservative habitable zone, making it a compelling candidate for future studies. The findings not only enhance our understanding of exoplanets but also contribute to the ongoing quest to find signs of life beyond our planet.
