Question

Mercury is one of the five classical planets visible with the naked eye and is named after the swift-footed Roman messenger god. Mercury has little atmosphere. It is made up mostly of oxygen, sodium, hydrogen. helium, and potassium. The thin atmosphere or exosphere, does little to prevent or slow dowm impacts from extraterrestrial objects, leaving the surface littered with craters. In appearance, it is similar to Earth's Moon. The planet is terrestrial. It has solid surface and is mainly made of silicate rocks or metals. The planet Mercury is mainly made up of iron. It has no moons. The planet's close proximity to the Sun makes having moons impossible as the star's strong gravitional pull would likely pull them out of the planet's orbit.

It is not known exactly when the planet was first discovered although it was first observed through telescopes in the seventeenth century by astronomers Galileo Galilei and Thomas Harriot. Only two spacecraft, both robotic and lauched by NASA, have visited Mercury so far, making it the least explored terrestrial planet. Mariner 10 launched in 1973 and imaged around 45% of the planet's surface from 1974 until its end of mission in March 1975. MESSENGER was launched in 2008 and entered Mercury orbit in 2011. It was the first spacecraft to do so. This mission lasted for four years before the probe succumbed to the planet's gravity and impacted its surface in 2015. It collected data and images and transmitted them back to Earth to be studied by scientists. BepiColombo, a joint space mission by the European Space Agency (ESA) and Japan Aerospace Exploration Agency (JAXA) was launched in October 2018 with the aim to reach Mercury in December 2025.
