- A planet-hunting orbital telescope designed to detect worlds beyond our solar system discovered—two planets
- NASA’s Transiting Exoplanet Survey Satellite, better known as TESS, made an early discovery of “super-Earth” and “hot Earth” planets
- discovery of Pi Mensae c, a “super-earth” planet 60 light-years away orbiting its sun every 6.3 days. The discovery of LHS 3844 b, a “hot-earth” planet 49 light-years away that orbits its sun every 11 hours
- All of the planets in our solar system orbit around the Sun. Planets that orbit around other stars are called exoplanets.
- A super-Earth is an extrasolar planet with a mass higher than Earth’s, but substantially below the masses of the Solar System’s ice giants, Uranus and Neptune, which have masses of 15 and 17 times Earth’s, respectively.
