Epsilon Indi Ab is a gas giant exoplanet orbiting the star Epsilon Indi A, about 11.9 light-years away in the constellation of Indus. The planet was confirmed to exist in 2018. [ 1 ] It orbits at around 30 AU (almost as far as Neptune from the Sun) with a period of around 180 years and a relatively high eccentricity of 0.4, and has a mass ...
Epsilon Indi, Latinized from ε Indi, is a star system located at a distance of approximately 12 light-years from Earth in the southern constellation of Indus. The star has an orange hue and is faintly visible to the naked eye with an apparent visual magnitude of 4.674. [ 2 ]
Epsilon Indi Ab, 12 light-years away, with its parent star Epsilon Indi A blacked out, as pictured by JWST in 2023. [1] Distribution of nearest known exoplanets as of March 2018 There are 7,408 known exoplanets , or planets outside the Solar System that orbit a star, as of January 26, 2024; only a small fraction of these are located in the ...
A paper published in October 2021 determines, using absolute astrometry measurements from the Hipparcos, Gaia DR2 data, and new radial velocity measurements from Keck/NIRC2 Ms-band vortex coronagraph images, a lower absolute mass of 0.65 times that of Jupiter, at an eccentricity close to 0.055 with the planet orbiting at around 3.53 AU inclined ...
The magnetic properties can be modelled by assuming that regions with a magnetic flux of about 0.14 T randomly cover approximately 9% of the photosphere, whereas the remainder of the surface is free of magnetic fields. [88] The overall magnetic activity of Epsilon Eridani shows co-existing 2.95 ± 0.03 and 12.7 ± 0.3 year activity cycles. [84]
DENIS 0255−4700 is an extremely faint brown dwarf 15.9 light-years (4.9 parsecs) from the Solar System in the southern constellation of Eridanus. [3] [7] It is the closest isolated L-type brown dwarf (no undiscovered L-dwarfs are expected to be closer), and only after the binary Luhman 16.
It came within 7.0 ly (2.1 pc) of the Sun about 10,900 years ago and has been moving away since that time. [17] Kapteyn's Star is distinctive in a number of regards: it has a high radial velocity, [ 13 ] orbits the Milky Way retrograde , [ 16 ] and is the nearest-known halo star to the Sun. [ 18 ] It is a member of a moving group of stars that ...
COCONUTS-2 b is a gas giant exoplanet that orbits the M-type star L 34-26. With a mass of 8 Jupiters, [5] it takes over one million years to complete one orbit around the star orbiting 7,506 AU away from it. [1] The planet was discovered in 2011 and was initially identified as a T9 free-floating brown dwarf WISEPA J075108.79−763449.6. [2]
