HD 209458 b is an exoplanet that orbits the solar analog HD 209458 in the constellation Pegasus, some 157 light-years (48 parsecs) from the Solar System.The radius of the planet's orbit is 0.047 AU (7.0 million km; 4.4 million mi), or one-eighth the radius of Mercury's orbit (0.39 AU (36 million mi; 58 million km)).
The period of this confirmed planet was the shortest until the confirmed discovery of WASP-12b on April 1, 2008. [4] The short period and proximity of the OGLE-TR-56 b to its host mean it belongs to a class of objects known as hot Jupiters. The radial velocity trend of OGLE-TR-56, caused by the presence of OGLE-TR-56 b.
The discovery was announced on 5 October 2018. HD 202772 Ab orbits its host star once every 3.3 days. It is an inflated hot Jupiter, and a rare example of hot Jupiters around evolved stars. It is also one of the most strongly irradiated planets known, with an equilibrium temperature of 2,100 K (1,830 °C; 3,320 °F). [67]

The lunar craft design takes into account the lower gravity and lighting conditions on the Moon. The Jupiter-bound Discovery is meant to be powered by a nuclear reactor at its rear, separated from the crew area at the front by hundreds of feet of fuel storage compartments. Although difficult to be recognized as such, actual nuclear reactor ...
