Mercury is the smallest planet in the Solar System. One of five planets visible with the naked eye a, Mercury is just 4,879 Kilometres across its equator, compared with 12,742 Kilometres for the Earth. Mercury is the second densest planet. Even though the planet is small, Mercury is very dense.
Among the four inner Solar System planets, Mercury is the smallest and very dense, its vast iron core dominating its internal structure.As the closest planet to the Sun it experiences extreme temperature variations at its surface, from about +430ºC, down to –180ºC. It has permanently shadowed regions at its poles that never see sunlight and thus enables ice to exist on its floor. Mercury ...
The view shown here is an orthographic projection of Mercury's south polar region, colored by an illumination map. Measurements from MESSENGER's MLA instrument during the spacecraft's greater than four-year orbital mission have mapped the topography of Mercury's northern...
Mercury is the fastest-orbiting planet in our solar system — it blazes around the Sun at 48 kilometers (30 miles) per second. Missions trying to enter orbit there typically fly past Earth, Venus, and/or Mercury itself, using gravitational nudges to adjust their trajectories. Only three spacecraft have ever visited Mercury.
Mercury, Innermost planet of the solar system. Its average distance from the Sun is about 36 million mi (58 million km), but its highly elliptical orbit carries it 7.5 million mi (12 million km) nearer to and farther from the Sun. It is the smallest major planet, having a diameter of about 3,030 mi (4,880 km) and a mass about one-eighteenth of ...
Sep 25, 2019 · This paradoxically makes Mercury the closest planet to Earth, a plurality of the time. Mercury was named after the Roman messenger god, because of its fast movements around the Sun. Mercury is the closest planet to the Sun at a distance of 57.91 million kilometers / 35.98 miles or 0.4 AU away.
Mercury is the smallest planet in the solar system with a diameter of 4,879 km and is one of five planets that is visible to the naked eye. After the Earth, Mercury is the second densest planet. Despite its small size, Mercury is very dense because it is composed mainly of heavy metals and rock – the main characteristic of terrestrial planets.
