A dwarf planet is a small planetary-mass object that is in direct orbit around the Sun, massive enough to be gravitationally rounded, but insufficient to achieve orbital dominance like the eight classical planets of the Solar System.
The list of minor planets consists of more than 700 partial lists, each containing 1000 minor planets grouped into 10 tables. The data is sourced from the Minor Planet Center (MPC) and expanded with data from the JPL SBDB (mean-diameter), Johnston's archive (sub-classification) and others (see detailed field descriptions below).
The number of dwarf planets in the Solar System is unknown. Estimates have run as high as 200 in the Kuiper belt [1] and over 10,000 in the region beyond. [2] However, consideration of the surprisingly low densities of many large trans-Neptunian objects, as well as spectroscopic analysis of their surfaces, suggests that the number of dwarf planets may be much lower, perhaps only nine among ...
As minor planet discoveries are confirmed, they are given a permanent number by the IAU's Minor Planet Center (MPC), and the discoverers can then submit names for them, following the IAU's naming conventions. The list below concerns those minor planets in the specified number-range that have received names, and explains the meanings of those names.

A planet in the Solar System beyond the asteroid belt, and hence refers to the gas giants. Jupiter, Saturn, Uranus and Neptune Pulsar planet: A planet that orbits a pulsar or a rapidly rotating neutron star. PSR B1257+12 A, B and C: Rogue planet: Also known as an interstellar planet.

According to the International Astronomical Union (IAU), a minor planet is an astronomical object in direct orbit around the Sun that is exclusively classified as neither a planet nor a comet. [ a ] Before 2006, the IAU officially used the term minor planet , but that year's meeting reclassified minor planets and comets into dwarf planets and ...
K2-18b, also known as EPIC 201912552 b, is an exoplanet orbiting the red dwarf K2-18, located 124 light-years (38 pc) away from Earth.The planet is a sub-Neptune about 2.6 times the radius of Earth, with a 33-day orbit within the star's habitable zone.
