About 640 light-years away in the constellation Pisces, there is an ultra-hot exoplanet called WASP-76b where it rains in the evening. Is it because of the mass distribution, so that Earth … While it’s one of the nearest exoplanets yet discovered, it’s hardly Earth-like – situated close to its host star with a scalding surface temperature of several hundred degrees Celsius. Proxima b is a little more massive than the Earth. EA43CH17-Heng ARI 11 May 2015 10:4 1. The ocean is filled with magma, not water. Is it because it is very difficult to discover an exoplanet of a low mass? An artist's illustration of what the super-Earth found around the orange-hued star HD 26965 (also known as 40 Eridani A) might look like. HD-106906b is a gaseous planet 11 times more massive than Jupiter. NASA/JPL-Caltech. In the process, they have gravitationally carved out a large gap in the disk. The day side receives thousands of times more radiation from its parent star than the Earth does from the Sun. "It's spinning around so fast that it's being pulled outwards at its equator! Both planets orbit a G2-type star of about the same temperature; however, the star hosting Kepler-452b is 6 billion years old -- 1.5 billion years older than our sun. Hot Earths are Earth-sized exoplanets that exist close to their stars, making them interesting but unlikely to support life, because most do not rotate—instead, like … It's currently the only super-Earth exoplanet that has water vapor in its atmosphere and could be within the right temperature to support life. It was taken by the SPHERE instrument on European Southern Observatory's Very Large Telescope. The findings concerning the recently found planet LTT 9779b were published today in Astrophysical Journal Letters. Planet Nine, potentially 10 times the size of Earth and orbiting far beyond Neptune in a highly eccentric orbit about the sun, was proposed in 2012 to explain perturbations in the orbits of dwarf planets just beyond Neptune’s orbit, so-called detached Kuiper Belt objects. This is an artist's impression of a free-floating rogue planet being detected in our Milky Way galaxy using a technique called microlensing. The planet weighs about 6.6 times the mass of Earth and is shown passing in front of LHS 1140.
