A team of astronomers have discovered a new super-Earth that is orbiting a distant star located some 36 light-years away in the constellation of Serpens, and is believed to be at least three times more massive than Earth.
Super-Earths by nature are described as a class of planets that are much more massive than Earth, but lighter than ice-giants such as Neptune or Uranus. According to the US’ National Aeronautics and Space Administration (NASA), such planets range between “twice the size of Earth and up to 10 times its mass.”
Astronomers noted in their recently published findings that they discovered the mysterious new exoplanet, since dubbed GJ 740 b, through the use of the radial velocity method, which has helped to unearth hundreds of exoplanets. Officials also used data collected over several years by the HARPS-N Red Dwarf Exoplanet Survey program and the CARMENES spectrograph in their search.
An analysis of the collected information ultimately led the team of researchers to determine that the faraway super-Earth has a mass of at least 2.96 Earth masses and orbits its host star – GJ 740 – every 2.377 days while maintaining a distance of 0.03 astronomical units, which places it outside of the system’s habitable zone.
Officials estimate the exoplanet’s temperature to be at roughly 1,033 degrees Fahrenheit.
However, that’s not all, folks. Researchers also indicated that their findings pinpoint to signs of a potential second, more massive planet orbiting the host star. The team speculates that this yet-to-be discovered body may be a “Saturn-mass planet of about 100 Earth masses.”
The findings are expected to be published in the upcoming edition of the peer-reviewed scientific journal Astronomy & Astrophysics.
