Scientists say they have found new evidence that there is a hidden planet in our solar system. For years, some astronomers have been suggesting that unusual behaviour on the edge of our solar ...
[1] [2] The widest separation between a planet and a star is OGLE-2008-BLG-092Lb, which is ~18 AU; the shortest separation is MOA-2015-BLG-337Lb, which is 0.24 AU. There are 7 known multi-planetary systems detected by microlensing, all of which have two planets. [3]
WASP-193b is a hot, transiting gas giant planet located approximately 1,232 light-years (378 pc) away [4] in the constellation of Hydra, orbiting the F-type star WASP-193. Its discovery was made by the WASP-South transit survey and announced in 2023.
Kepler-452b (sometimes quoted to be an Earth 2.0 or Earth's Cousin [4] [5] based on its characteristics; also known by its Kepler object of interest designation KOI-7016.01) is a candidate [6] [7] super-Earth exoplanet orbiting within the inner edge of the habitable zone of the sun-like star Kepler-452 and is the only planet in the system discovered by the Kepler space telescope.
The planet is about the size of Venus, so slightly smaller than Earth, and may be temperate enough to support life, the researchers said. Dubbed Gliese 12 b, the planet takes 12.8 days to orbit a ...
The planet is located some 1,200 light-years away. A light-year is 5.8 trillion miles. It's the second-lightest exoplanet found so far based on its dimensions and mass, according to the researchers.
On its discovery, the planet was designated PSR 1257+12 C and later PSR B1257+12 C. It was discovered before the convention that extrasolar planets receive designations consisting of the star's name followed by lowercase Roman letters starting from "b" was established. [12]
First spotted in 2016, the disk around a star 1,000 light-years away was not confirmed to be a hotbed for new, emerging planets until recent obs Astronomers find the biggest known batch of planet ...
