Interesting Facts for Kids 1: Planet Mercury Definition:
Mercury can be described as the closest planet to our Sun and the smallest in our solar system. It has the most extreme surface temperature range out of all the known planets. The color of Mercury is gray and its name derives from the Roman God of Science. There are other names associated with Mercury which include Apollo and Hermes.

Interesting Facts for Kids 2: How far is Planet Mercury from the Sun?
Mercury is located approximately 58 million km from the Sun. When its closest to the Sun, it is situated at approximately 47 million kms away, and when it is positioned at its furthest point away from the Sun, this distance increases to around 70 million kms.

Interesting Facts for Kids 3:
How far is Planet Mercury from the Earth?
The distance of Mercury from our Planet Earth is approximately 77 million km (48 million miles). Mercury's average distance from the Sun is 58 million kms which is almost three times the Earth's distance from the Sun.

Interesting Facts for Kids 4: Where is Planet Mercury located?
Mercury is officially classed as an inner planet because its orbit lies on the inner side of the asteroid belt where it is located between the asteroid belt and the Sun. For this reason, Mercury is also categorized as a terrestrial planet. It is located between the Sun and Venus. The closest planet to Mercury is Venus.

Interesting Facts for Kids 5: How long does it take Planet Mercury to orbit the Sun?
It takes Planet Mercury around 88 Earth days to complete a full orbit of the Sun. The planet's orbit speed is approximately 172,341 kilometers per hour (107,088 miles). Mercury revolves around the Sun faster than the other planets as it is the closest point.

Interesting Facts for Kids 6:- How big is Planet Mercury?
The diameter of Mercury is approximately 4880km and its mass is 328.5E21 kg. It is the smallest known planet in our solar system. Pluto is smaller than Mercury but it is now categorized as a dwarf planet. Mercury is around three times smaller than Earth.

Interesting Facts for Kids 7: What is the weather like on Planet Mercury?
An atmosphere is created by the gases surrounding a planet. The atmosphere on Mercury is so slight, there almost isn't one. This means that the planet doesn't retain heat well. Mercury's temperature can vary significantly from extremely cold to extremely hot. The planet does not experience seasons as its axis has the smallest tilt of all the planets in our solar system.

Interesting Facts for Kids 8: Does Planet Mercury have moons or rings?
Mercury does not have any moons, otherwise known as satellites, and there are no rings surrounding the planet. Some of the other planets have way more than one moon!

Interesting Facts for Kids 9: What is the surface temperature of Planet Mercury like?
The surface temperature of Mercury is subject to extreme fluctuations. The temperature range changes depending on the planet's distance from the Sun. The closest surface side to the Sun can reach extremely high temperatures of up to 427 degrees Celsius. However, the surface side furthest from the Sun can subject to extremely low temperatures as low as -183°degrees Celsius (the temperature can decrease further still during night time hours!). The varying surface temperature experienced on Mercury is more extreme than any other solar system planet. The surface can be described as solid, desolate, and heavily cratered by past meteorite impacts. The heavy craters can be compared to the Earth's moon which suggests that Planet Mercury has also been inactive for billions of years. Many of the craters were created during the history of the solar system when billions of comets shot through the solar system leaving scars all over the planets and moons.

Interesting Facts for Kids 10: What is the composition and structure of Planet Mercury?
Mercury, Venus, Earth and Mars can be described as terrestrial planets, otherwise known as rocky planets. Mercury has a dense, compact, iron metallic core which is responsible for the majority of the its total mass. This planet has very high density. It is composed of approximately 70% metallic material and only 30% silicate material (mineral compounds).

Interesting Facts for Kids 11: Which space crafts have visited Planet Mercury?
Only two spacecrafts have visited Planet Mercury so much of the information we have has in fact been discovered in recent years. The two spacecraft that have participated in visits to Mercury are the Mariner 10 which was sent in the 1970s and Messenger which was launched in 2004 and became the first to orbit the planet between 2011-2015.

Interesting Facts for Kids 12: Planet Mercury Summary:
Planet Mercury is located between the Sun and Venus. It is the 1st closest planet to the Sun, and therefore has the fastest orbit of the Sun. There are no moons captured by its gravity and scientists believe that the heavily cratered planet has been inactive for billions of years.
