The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...
This list of exoplanets discovered in 2023 is a list of confirmed exoplanets that were first reported in 2023. For exoplanets detected only by radial velocity, the listed value for mass is a lower limit. See Minimum mass for more information. Name Mass (M J) Radius (R J) Period (days) Semi-major axis (AU) Temp. (K) Discovery method Distance (ly) Host star mass (M ☉) Host star temp. (K ...
On May 10, 2016, NASA announced that the Kepler mission has verified 1,284 new planets. [20] Based on some of the planet's sizes, about 550 could potentially be rocky planets. Nine of these orbit in their stars' habitable zone. [20]
14 April 2023 Jupiter/Ganymede orbiter [495] Chandrayaan-3: 14 July 2023 Lunar orbiter, lander and rover; first soft landing near the lunar South Pole [496] [497] Luna 25: 10 August 2023 Attempted lunar south pole lander (crashed into Moon) [498] [499] Aditya-L1: 2 September 2023 Sun-observing spacecraft at Sun–Earth L 1 [500] SLIM (LEV-1, LEV-2)
GJ 1214 b (sometimes Gliese 1214 b, [6] also named Enaiposha since 2023 [2]) is an exoplanet that orbits the star GJ 1214, and was discovered in December 2009. Its parent star is 48 light-years (15 pc) from the Sun, in the constellation Ophiuchus. At the time of its discovery, GJ 1214 b was the most likely known candidate for being an ocean planet.
Seven planets are going to be retrograde in the summer of 2023. Here are the dates for Mercury retrograde, Venus retrograde, Saturn retrograde, Neptune retrograde, Pluto retrograde and more.
Tadmor: The radial velocity variations of the star Errai were announced in 1989, consistent with a planet in a 2.5-year orbit. [5] However, misclassification of the star as a giant combined with an underestimation of the orbit of the Gamma Cephei binary, which implied the planet's orbit would be unstable, led some astronomers to suspect the variations were merely due to stellar rotation.
