Using the solar system as a point of reference, the host star is about 10% the mass of our Sun, and the planet would have a mass somewhere between that of Earth and Neptune, and would orbit at a location between Venus and Earth from the parent star. 31 lightyears away, a new planet has been found by NASA's Transiting Exoplanet Survey Satellite. According to the study, the super-Earth's host star is about 10% the mass of our sun, and the planet would have a mass somewhere between that of Earth and Neptune. The newly discovered exoplanets, GJ887b and GJ887c, are so-called super-Earths, meaning their size ranks roughly between our planet and Neptune. "These experiments detect around 3000 microlensing events each year, the majority of which are due to lensing by single stars," the paper's co-author Associate Professor Albrow notes. The planet is one of only a handful that have been discovered with both size and orbit comparable to that of Earth. An international team of astronomers has found 60 new planets orbiting stars close to Earth’s solar system, including a rocky “super Earth.” If the planet has a thick atmosphere it may be able to support life.

The nearest single star to the Sun hosts an exoplanet at least 3.2 times as massive as Earth — a so-called super-Earth. Due to the host star having a smaller mass than our Sun, the planet would have a 'year' of approximately 617 days. Proxima c is at least 6 times bigger than Earth itself and as such is described as a super-Earth. Those properties place 55 Cancri e in the "super-Earth" class of exoplanets, a few dozen of which have been found.
