Oct 25, 2024 · GJ 357 d is a Neptune-like exoplanet that orbits a M-type star. Its mass is 6.1 Earths, it takes 55.7 days to complete one orbit of its star, and is 0.204 AU from its star. Its discovery was announced in 2019.

Gliese 357 d is an exoplanet, considered to be a "Super-Earth" within the circumstellar habitable zone of its parent star. [3][4][5][6] The planet orbits Gliese 357, 31 light-years from the Solar System, [4] The system is part of the Hydra constellation. [4] The planet was discovered by the TESS team and announced in July 2019.

Jul 31, 2019 · The new worlds orbit a star named GJ 357, an M-type dwarf about one-third the Sun’s mass and size and about 40% cooler that our star. The system is located 31 light-years away in the constellation Hydra.

GJ 357 (Gliese 357) is an M-type main sequence star with an unusually low star spot activity. [8] . It is located 31 light-years from the Solar System, [9] in the Hydra constellation. [9] The star has three confirmed exoplanets in its orbit. [10] .

Jul 31, 2019 · The exoplanet, named GJ 357 d, is believed to be around twice the size of Earth and harbor six times Earth's mass. Located in the outer edge of its host star's "habitable zone," scientists...

Aug 3, 2019 · The planet named GJ 357 d, is six times larger than Earth. It orbits a dwarf star with two other previously unknown planets. This potential "super Earth" is located within the outer edge of its...

Jul 31, 2019 · Tour the GJ 357 system, located 31 light-years away in the constellation Hydra. Astronomers confirming a planet candidate identified by NASA’s Transiting Exoplanet Survey Satellite subsequently found two additional worlds orbiting the star.

GJ357d is a rocky, and habitable, planet about 1.5 times the radius of the Earth. If so, we can figure out how strong gravity would be on the surface of this planet. It is an equation derived from combining Newtons second law with Newton’s universal law of gravitation.

Aug 1, 2019 · GJ 357 d is about six times larger than Earth and orbits a dwarf sun called GJ 357, much smaller than our own, making the journey around the sun in just 55.7 days. The international team of...

Jul 30, 2019 · Here we model under what conditions GJ 357 d could sustain surface habitability and present planetary models as well as synthetic transmission, reflection and emission spectra for a range of models for GJ 357 d from water worlds to Earth-like models.
