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 25, 2024 · 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 0.020807 AU from its star. Its discovery was announced in 2005.

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.

Exoplanet Gliese 876 d orbits star Gliese 876 that lies 15 light years away from the Sun. It weighs about 6.9 Earth masses and orbits its star much closer than Earth orbits Sun.

Gliese 876, at center, is a dim red dwarf star with a planetary system -- larger image. System Summary. Previously well known as Ross 780, this dim star lies around 15.2 light-years (Plx=214.6 ± 0.2 mas) from Sol (Benedict et al, 2002).

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.

Gliese 876 is a class M4 star with a visual magnitude of 10.1. Its luminosity is 0.0124 L Sun and mass of 0.32 M Sun. Using high-resolution Echelle type spectrometers – the Hamilton and HIRES – a 2.1 M J mass planet was discovered orbiting Gliese 876 at a distance of only 0.2 AU.

Gliese 876 d is the closest planet to the star. Gliese 876 d is located in an orbit with a semimajor axis of only 0.0208 AU (3.11 million km).

Jun 13, 2005 · Gliese 876d is an exoplanet approximately 15 light-years away in the constellation of Aquarius. The planet was the third planet discovered orbiting the red dwarf Gliese 876. It was the lowest- mass extrasolar planet apart from the pulsar planets orbiting PSR B1257+12 at the time of its discovery.

Red dwarf Gliese 876 is located 15 light years away from the Sun. It is a single star of spectral class M4 V, that has 33 % of solar mass. There are multiple known exoplanets in this system.
