The sizes are listed in units of Jupiter radii (R J, 71 492 km).This list is designed to include all planets that are larger than 1.6 times the size of Jupiter.Some well-known planets that are smaller than 1.6 R J (17.93 R 🜨 or 114 387.2 km) have been included for the sake of comparison.
Exoplanets have been discovered using several different methods for collecting or combining direct images to isolate planets from the background light of their star. Non-Redundant Aperture Masking Interferometry is a method of combining the views of multiple telescopes into a single image, while the other methods are algorithms for combining ...
HD 100546, also known as KR Muscae, is a pre-main sequence star of spectral type B8 to A0 located 353 light-years (108 parsecs) from Earth in the southern constellation of Musca. [4] The star is surrounded by a circumstellar disk from a distance of 0.2 to 4 AU, and again from 13 AU out to a few hundred AU, with evidence for a protoplanet ...
ROXs 42Bb is a directly imaged planetary-mass companion [1] to the binary M star ROXs 42B, [4] a likely member of the Rho Ophiuchi cloud complex.The companion was announced/discovered on October 17, 2013, by University of Toronto astronomer Thayne Currie.
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.
Scientists say they are rethinking how the weather works after creating a 3D map of an exoplanet 900 light-years away and discovering a world with jet streams fueling wild storms.
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 ...
Largest semi-major axis ratio between consecutive planets HD 83443 b and HD 83443 c: HD 83443: 205.1 HD 83443 b and c have semi-major axes of 0.039 AU and ~8.0 AU, [98] respectively; hence the planet c is about 205.1 times further from star than b. Highest rate of orbital period decay Kepler-1658b: Kepler-1658 131 +20 −22 ms/year [99]
