At 17 Earth masses, it is well above the 10 Earth mass upper limit that is commonly used for the term 'super-Earth' so the term mega-Earth has been proposed. [14] However, in July 2017, more careful analysis of HARPS-N and HIRES data showed that Kepler-10c was much less massive than originally thought, instead around 7.37 (6.18 to 8.69) M E ...
It is the second super-Earth for which astronomers have determined the mass and radius, giving vital clues about its structure. The radius of GJ 1214 b can be inferred from the amount of dimming seen when the planet crosses in front of its parent star as viewed from Earth, yielding a radius of 2.742 +0.050 −0.053 R 🜨. [3]

Gliese 667 Cc is a super-Earth, an exoplanet with a mass and radius greater than that of Earth, but smaller than that of the giant planets Uranus and Neptune. It is heavier than Earth with a minimum mass of about 3.7 Earth masses. [5] The equilibrium temperature of Gliese 667 Cc is estimated to be 277.4 K (4.3 °C; 39.6 °F). [6]
Kepler-442b is a super-Earth, an exoplanet with a mass and radius bigger than Earth's but smaller than the ice giants Uranus and Neptune. It has an equilibrium temperature of 233 K (−40 °C; −40 °F). [3] It has a radius of 1.34 R 🜨 and the mass estimated to be 2.36 M E. [8]
But study author Michael Hippke say that on a super-earth 70% wider than Earth and 10 times larger, escape velocity for a conventional rocket would be roughly 2.4 times greater.
Lacaille 9352 c is considered a Super-Earth with a minimum mass of 7.6 Earth masses. [4] With an orbital period of 21.8 days, the exoplanet is located at 0.12 AU from the star, which is close to the inner edge of the habitable zone (but still outside). [5] The exoplanet has a calculated equilibrium temperature of 352 K (79 °C; 174 °F). [2]
Kepler-452b (sometimes quoted to be an Earth 2.0 or Earth's Cousin [4] [5] based on its characteristics; also known by its Kepler object of interest designation KOI-7016.01) is a candidate [6] [7] super-Earth exoplanet orbiting within the inner edge of the habitable zone of the sun-like star Kepler-452 and is the only planet in the system discovered by the Kepler space telescope.
