For the small outer irregular moons of Uranus, such as Sycorax, which were not discovered by the Voyager 2 flyby, even different NASA web pages, such as the National Space Science Data Center [6] and JPL Solar System Dynamics, [5] give somewhat contradictory size and albedo estimates depending on which research paper is being cited.
First planet discovered to have a retrograde orbit [134] and first to have quartz (crystalline silica, SiO 2) in its clouds. [135] Has an exteremely low density of 0.08 g/cm 3, [136] the lowest of any exoplanet when it was discovered, and was possibly the largest exoplanet at the time of discovery, with a radius of 1.92 R J. [137] KELT-19 Ab: 1 ...
This is a list of trans-Neptunian objects (TNOs), which are minor planets in the Solar System that orbit the Sun at a greater distance on average than Neptune, that is, their orbit has a semi-major axis greater than 30.1 astronomical units (AU). The Kuiper belt, scattered disk, and Oort cloud are three conventional divisions of this volume of ...

This is a list of exoplanets detected by gravitational microlensing. The phenomenon results in the background star's light being warped around a foreground object, causing a distorted image. If the foreground object is a star with an orbiting planet, we would observe an abnormally bright image. By comparing the luminosity and light distortion ...
This list of exoplanets discovered in 2024 is a list of confirmed exoplanets that were first reported in 2024. For exoplanets detected only by radial velocity , the listed value for mass is a lower limit.
This list of exoplanets discovered in 2022 is a list of confirmed exoplanets that were first reported in 2022. For exoplanets detected only by radial velocity, the listed value for mass is a lower limit. See Minimum mass for more information. On 31 March 2022, K2-2016-BLG-0005Lb was reported to be the most distant exoplanet found by Kepler to ...
