Post-processing of observational data to enhance signal strength of off-axial bodies (i.e. exoplanets) can be accomplished in a variety of ways. All methods are based on the presence of diversity in the data between the central star and the exoplanet companions: this diversity can originate from differences in the spectrum, the angular position ...
Four exoplanets of the HR 8799 system imaged by the W. M. Keck Observatory over the course of seven years. Motion is interpolated from annual observations. Comparison of the size of exoplanets orbiting Kepler-37 to Mercury, Mars and Earth. An exoplanet or extrasolar planet is a planet outside the Solar System. The first possible evidence of an ...
Animation showing exoplanets by year from 1991 until 2022 (March) with a total of 5005 discoveries [1] An exoplanet (extrasolar planet) is a planet located outside the Solar System. The first evidence of an exoplanet was noted as early as 1917, but was not recognized as such until 2016; no planet discovery has yet come from that evidence. [2]
Astronomers have invented a new method for searching out and spotting exoplanets. It combines two previous methods: astrometry and direct imaging.

Two teams of scientists have discovered a theoretically habitable planet called Gliese 12b that’s smaller than Earth but bigger than Venus, just 40 light-years away.
Astrometry has been used to discover a handful number of exoplanets, mostly gas giants more massive than Jupiter. It is based on measuring a star's proper motion, and seeing how that position changes over time: a planet with a sufficiently large mass is able to gravitationally pull its host star, making its proper motion vary over large timescales.
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.
