Mar 28, 2025 · GJ 876 d is a Neptune-like exoplanet that orbits a M-type star. Its mass is 6.83 Earths, it takes 1.9 days to complete one orbit of its star, and is 0.02080665 AU from its star. Its discovery was announced in 2005.

Gliese 876 d is an exoplanet 15.2 light-years (4.7 parsecs) away in the constellation of Aquarius. The planet was the third planet discovered orbiting the red dwarf Gliese 876, and is the innermost planet in the system.

Oct 10, 2024 · GJ 876 d is a Confirmed extrasolar planet (exoplanet) that orbits the star Ross 780 in the constellation of Aquarius

Gliese 876 is a red dwarf star 15.2 light-years (4.7 parsecs) away from Earth in the constellation of Aquarius. It is one of the closest known stars to the Sun confirmed to possess a planetary system with more than two planets, after GJ 1061, YZ Ceti, Tau Ceti, and Wolf 1061; as of 2018, four extrasolar planets have been found to orbit the star ...

Nov 20, 2005 · High-precision, high-cadence radial velocity monitoring over the past 8 yr at the W. M. Keck Observatory reveals evidence for a third planet orbiting the nearby (4.69 pc) dM4 star GJ 876. The residuals of three-body Newtonian fits, which include GJ 876 and Jupiter-mass companions b and c, show significant power at a periodicity of 1.9379 days.

Gliese 876 is a red dwarf only 15 light years from Earth in the constellation Aquarius. The orbits of the outer three planets are locked in a Laplace reasonance. This resonance is also present in the moons of Jupiter: Io, Europa, Ganymede.
