Mercury is the first planet from the Sun and the smallest in the Solar System. In English, it is named after the ancient Roman god Mercurius , god of commerce and communication, and the messenger of the gods. Mercury is classified as a terrestrial planet, with roughly the same surface gravity as Mars.
Discovery Rupes is an escarpment on Mercury, approximately 267 kilometers (166 mi) long, located at latitude 58.52 N and longitude 53.25 W. [1] It was formed by a thrust fault, thought to have occurred due to the shrinkage of the planet's core as it cooled over time. The scarp cuts through Duccio crater.
The exploration of Mercury has a minor role in the space interests of the world. It is the least explored inner planet. [1] As of 2015, the Mariner 10 and MESSENGER missions have been the only missions that have made close observations of Mercury.
A spacecraft has beamed back some of the best close-up photos ever of Mercury’s north pole. The European and Japanese robotic explorer swooped as close as 183 miles (295 kilometers) above ...
The planets were detected by observing small dips in the star's brightness when they crossed in front of it from our vantage point. The innermost planet takes about nine days to orbit the star ...
The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...
Astronomers have discovered a rare in-sync solar system with six planets moving like a grand cosmic orchestra, untouched by outside forces since their birth billions of years ago. The find ...
BepiColombo is a joint mission of the European Space Agency (ESA) and the Japan Aerospace Exploration Agency (JAXA) to the planet Mercury. [4] The mission comprises two satellites launched together: the Mercury Planetary Orbiter (MPO) and Mio (Mercury Magnetospheric Orbiter, MMO). [5]
