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 ...
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 ...
