Best Sub Neptune
K2-18b is a sub-Neptune exoplanet orbiting the M dwarf star K2-18. Located within its star’s habitable zone, it has garnered significant attention due to potential liquid water on its surface. Scientists are studying this planet to understand atmospheric compositions and assess conditions suitable f...
GJ 1214 b is a sub-Neptune or "mini-Neptune" exoplanet discovered in 2009 orbiting a red dwarf star approximately 42 light-years from Earth. It is one of the few known low-mass planets that frequently transits its host star, making it an ideal candidate for atmospheric studies. Early spectroscopic o...
Kepler-11b is a sub-Neptune exoplanet orbiting the Sun-like star Kepler-11, approximately 2,000 light-years from Earth. Announced in 2011, it is one of six confirmed planets in the Kepler-11 system, which was notable for having one of the most compact multi-planet configurations discovered. Kepler-1...
Kepler-11c is an exoplanet orbiting the Sun-like star Kepler-11, located approximately 2,000 light-years from Earth in the constellation Cygnus. The Kepler-11 system, announced by NASA in 2011, is notable for having six confirmed transiting planets in a remarkably compact orbital configuration, with...
A circumbinary exoplanet discovered in 2019 using NASA's Kepler space telescope, notable for having the largest radius of the three known planets within this binary star system.
Third of six confirmed planets orbiting Kepler-11, part of the 2011 announcement that revealed how tightly packed planetary systems can be arranged within a single solar system.
Kepler-11e is a sub-Neptune exoplanet orbiting the Sun-like star Kepler-11, discovered by NASA's Kepler space telescope. As the fourth of six confirmed planets in this system, it completes an orbit around its host star approximately every 32 days. The planet is distinguished by its exceptionally low...
Kepler-11f is one of six known transiting planets orbiting the Sun-like star Kepler-11. Announced in 2011, it belongs to an unusually compact system in which five planets orbit closer to their star than Mercury does to the Sun. Transit timing variations allowed researchers to estimate planetary mass...
Kepler-11g is an extrasolar planet orbiting the sun-like star Kepler-11, located approximately 2,000 light-years from Earth. Announced by NASA in 2011, it is the largest and outermost of six confirmed planets within this densely packed planetary system. Unlike its five inner companions that orbit cl...
Discovered by NASA's TESS satellite in 2019, HD 21749 b is a sub-Neptune exoplanet notable for having one of the longest orbital periods of any planet found by the initial TESS mission.
Discovered in 2018, Wolf 503 b is a super-Earth exoplanet notable for orbiting a nearby orange dwarf star, making it a prime candidate for future atmospheric study by space telescopes.
Innermost of five planets in the Kepler-62 system announced in 2013, a hot super-Earth orbiting its K-type host star every ~5.7 days, well inside the inner edge of the habitable zone.
Second planet in the Kepler-62 system announced in 2013, a small hot super-Earth orbiting its K-type star every ~12.4 days, too close to its host for conditions favorable to liquid water.
Super-Earth in the Kepler-62 system announced in 2013, roughly 1.95 times Earth's radius, orbiting its K-dwarf host every ~18.2 days just interior to the inner edge of the habitable zone.
Fifth planet in the Kepler-90 system, a sub-Neptune ~2.9 times Earth's radius with an orbital period of ~125 days, placing it in the temperate zone of its sun-like host star.
Fourth planet in the Kepler-90 system, a sub-Neptune roughly 2.7 times Earth's radius completing an orbit every ~92 days around the system's sun-like star.
Third planet in the Kepler-90 system, a sub-Neptune about 2.9 times Earth's radius with an orbital period of ~60 days around its sun-like host star.
Second planet in the eight-planet Kepler-90 system, a small hot super-Earth (~1.2 Earth radii) orbiting its host star every ~8.7 days at a distance comparable to Mercury's orbit.
Innermost confirmed planet in the Kepler-90 system, a hot super-Earth orbiting its sun-like star every ~7 days in the first star system outside our own known to host eight planets.
