The closest planet to the Sun is only about as wide as the Atlantic Ocean! 🌊 18 Mercuries would fit into the Earth. The planet does not have an atmosphere, just like it is on all the other planets. There is no water present on this dangerous planet either! 💧 There temperatures vary between -180°C and 430°C/-290°F and 842°F. 🌡️

This is also the fastest planet! It speeds through space with 50km per second/31 miles per second. 🚀

The BepiColombo mission was launched in October 2018 and now travels in space towards Mercury which it will reach by 2025. It will orbit the planet to solve mysteries about Mercury. 🛰️

Venus - named after the Roman goddess of beauty - is also known as the evening or morning star. ⭐ Yellow clouds made of sulfur and sulfuric acid cover the entire planet causing light to reflect off the surface. ☁️

This makes Venus the second brightest object in the night sky after the Moon. 🌙 Venus is very similar to Earth in terms of size and material.

However, it is the hottest planet in the Solar system with temperatures reaching 460°C/480°F. 🔥 The surface of Venus hosts thousands of volcanoes, craters and super-high mountain ranges. 🌋

Earth is the fifth largest planet of our solar system and has one large natural satellite, the Moon. 🌙

Did you know that all planets were named after Roman and Greek gods and goddesses, except the Earth. 🏛️ The name 'Earth' nevertheless is more than 1,000 years old and means just 'ground'. 🌱

Everything one ever knows is here. This is the only place where life is known to currently exist. 🧬 Most of the Earth's surface (about 70%) is covered with water. 🌊

Mars, the most likely candidate for a future human habitat, is affected by huge dust storms that occur every now and then and cover the entire planet! 🌪️

Mars is very cold and dry but water exists in form of ice at the North and South poles. ❄️ The surface of Mars has many craters, deep valleys and volcanoes. 🌋

The largest peak on the red planet is a volcano called Olympus Mons, which is three times higher than Mount Everest! ⛰️ Mars has two moons called Phobos and Deimos. 🌙

Jupiter is the largest planet in the solar system. 🌟 The most famous feature on the surface of the planet is the 'Great Red Spot' which is actually a storm that has been blowing for about 350 years! 🌪️

Jupiter has some of the largest moons in the solar system and one in particular, Europa might be able to sustain life in an ocean below its icy surface. 🧊

There is one spacecraft currently orbiting Jupiter called Juno. Juno is trying to solve how the planet formed and finding out more about the winds that occur. 🛰️

Saturn is a gas giant just like Jupiter, Neptune and Uranus. This means that it doesn't really have a proper solid surface as it is mainly made up of gases with a small rocky core. 💨

Saturn is the second largest planet and is known for its rings, although the other gas giants also have these kinds of rings, only Saturn's rings can be seen the clearest. 💍

Saturn's moon, Titan is the second largest in the solar system. 🌙 In 2005, NASA and ESA landed a space-probe called 'Huygens' on Titan revealing the composition and the landscape of this moon. 🛰️

Uranus is the second furthest planet from the Sun and therefore also has to travel a pretty long time to go once around our home star. ⏰ It takes Uranus roughly 84 years to orbit once around the Sun! 🌞

Uranus is a blue planet, not because of water, but because of gases that make it appear blue. 💙

Uranus orbits on its side, which means that its seasons are completely different to ours. Summer and winter each take 21 years at the north and south poles! ❄️☀️

Neptune is closely related to Uranus, the atmosphere is composed of almost the same gases and just like Uranus, Neptune also appears blue. 💙 Neptune inherits its name from the Roman god of the sea as reference to its deep blue color. 🌊

Neptune is the furthest planet from the Sun and it takes 165 years for Neptune to go once around the Sun. ⏰

No space probes have ever visited Neptune or its partner Uranus but a fly-by was made by the space probe Voyager 2 in 1989. 🚀
