A Super-Earth Exoplanet is an exoplanet that has a mass greater than Earth's but less than ice giants (enabling planetary classification and exoplanet research).
- Context:
- It can typically possess Super-Earth Mass Range between 1.5 and 10 earth masses (distinguishing it from earth-sized exoplanets and mini-neptune exoplanets).
- It can typically exhibit Super-Earth Radius Characteristics between 1.25 and 2.5 earth radii (affecting its surface gravity and atmospheric retention capability).
- It can typically orbit within various Super-Earth Orbital Zones around its host star (including both habitable zone and non-habitable zone locations).
- It can typically maintain Super-Earth Atmospheric Composition ranging from thin atmospheres to substantial gaseous envelopes (depending on its formation history and stellar environment).
- It can typically possess Super-Earth Interior Structure with higher internal pressures than earth-like planets (influencing its geological activity and magnetic field generation).
- ...
- It can often feature Super-Earth Surface Characteristics that vary between rocky surfaces and volatile-rich compositions (affecting its potential habitability).
- It can often undergo Super-Earth Formation Processes in protoplanetary disks (through core accretion or gravitational instability mechanisms).
- It can often exhibit Super-Earth Orbital Dynamics influenced by migration processes and gravitational interactions with other planetary system bodies.
- It can often present Super-Earth Detection Signatures through transit photometry, radial velocity measurements, and direct imaging techniques.
- ...
- It can range from being a Rocky Super-Earth Exoplanet to being a Gas-Rich Super-Earth Exoplanet, depending on its composition and formation history.
- It can range from being a Hot Super-Earth Exoplanet to being a Cold Super-Earth Exoplanet, depending on its orbital distance from its host star.
- It can range from being a Low-Density Super-Earth Exoplanet to being a High-Density Super-Earth Exoplanet, depending on its internal structure and material composition.
- ...
- It can serve as Super-Earth Research Target for exoplanet characterization missions and ground-based observatory programs.
- It can contribute to Super-Earth Frequency Analysis in stellar populations (informing exoplanet distribution models).
- It can support Super-Earth Habitability Assessment through comparative planetology and astrobiology investigations.

- Super-Earth Exoplanet Categories, such as:
- Counter-Examples:
- Terrestrial Planets, which possess masses below the super-earth threshold of 1.5 earth masses.
- Mini-Neptune Exoplanets, which exceed the super-earth upper mass limit and have substantial hydrogen-helium envelopes.
- Gas Giant Exoplanets, which have significantly larger masses and primarily consist of hydrogen and helium composition.
