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.

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. See Minimum mass for more information.
82 G. Eridani d (HD 20794 d) is an exoplanet, possibly rocky, orbiting the solar-type star 82 G. Eridani. It is at least five times more massive than Earth and has an orbit partially within the habitable zone of its host star. Depending on its physical characteristics, which are poorly known, it could harbour life as we know it.

From the total of 5,086 stars known to have exoplanets (as of January 26, 2024), there are a total of 1,033 known multiplanetary systems, [1] or stars with at least two confirmed planets, beyond the Solar System. This list includes systems with at least three confirmed planets or two confirmed planets where additional candidates have been proposed.
The densest transiting exoplanet known is CoRoT-3b, which has density of 26.4 g/cm 3; the diffusest transiting planet known is Kepler-12b, which has density of only 0.111 g/cm 3. Previously, the longest period of any transiting planets was Kepler-1647b , which takes 1107 days to orbit its (double) stars.
It was the third (and most recent) exoplanet to be discovered in orbit around this star; the other two, HD 63433 b and c, were discovered in 2020. [ 1 ] [ 4 ] Orbiting its star at a distance of 0.0503 astronomical units (7,520,000 km), HD 63433 d is the innermost planet orbiting HD 63433, and completes an orbit around it just every 4 days.

It was the youngest transiting exoplanet until the discovery of IRAS 04125+2902 b in 2024. There are relatively few other exoplanets discovered to date with an age this young, all of which are non-transiting (with some that were detected around hot A-type and B-type stars , such as HD 95086 b and HIP 78530 b , however these could be brown ...
