Planet Mercury

Hello Friends,

Today apart from computer and technology we are going to discuss about Planet Mercury


Mercury is the smallest planet in the Solar System and the closest to the Sun. The shortest of all the Sun’s planets

 It is named after the Roman god Mercurius

How hot is Mercury?

Mercury’s sun-facing side is scorched by temperatures of around 430°C, hot enough to melt lead.

How long is a day on Mercury?

Days on Mercury are very long because the planet rotates very slowly. One day-long spin lasts for 59 Earth days. But because of its fast orbit, one Mercury year takes 88 Earth days. This means that two years on Mercury lasts for only three days.

Who discovered Mercury?

Mercury is one of the five classical planets visible with the naked eye and is named after the swift-footed Roman messenger god. 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.

Thank you

Have a nice day 🙂
