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 ...
While no scientist has stated to believe GJ 1214 b is an ocean planet, if GJ 1214 b is assumed to be an ocean planet, [22] i.e. the interior is assumed to be composed primarily of a water core surrounded by more water, proportions of the total mass consistent with the mass and radius are about 25% rock and 75% water, covered by a thick envelope ...

The planet is located some 1,200 light-years away. A light-year is 5.8 trillion miles. It's the second-lightest exoplanet found so far based on its dimensions and mass, according to the researchers.
The FY2024 budget request for VERITAS at $1.5M, released in March 2023, represented a near-complete freeze of the mission attested to be "functionally a soft cancellation". [14] This has been reverted in the FY24 bill released March 3, requesting NASA seek sufficient funding for the VERITAS Venus mission to enable a launch by the end of the decade.
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 ...
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]
