For many years, humans were unaware of the Solar System and The Solar thought that planet Earth was at the centre of the universe. System The Solar System is made up of the Sun as well as smaller parts that include planets, moons, asteroids, dwarf planets and comets. The planets orbit 53 around the Sun.. Moons orbit Earth around their The Sun The Moon Comet planets. Mercury Uranus Saturn has 53 Saturn named moons. Jupiter Neptune The largest is called Titan.

It has a diameter of 4,880 km, making it around a third of the size of Earth. Mercur y 10-15 Mercury is the planet closest to the Sun. It can be seen with the naked eye and is visible from Earth for much of the year. Once every ten to fifteen years, Mercury can be seen crossing Mercury has the in front of the Sun. This event widest temperature is known as a transit. -173 427 extremes of all the Mercury orbits the Sun once planets, with possible every 88 Earth days. It travels temperatures ranging faster than any other planet from -173oC to 427oC. at 50km per second. Mercury’s surface is covered in craters. It has a thick, partly molten core and a thin outer 15,000,000 crust. The surface looks very similar to the Earth’s moon. Mercury is 15 million km from the Sun. 1974 2009 Only two spacecraft have ever visited Mercury. It is very difficult to reach Mercury because it is so close to the Sun. (Venus has had 32 visits.) Mercury has no atmosphere, which means that there is no weather on the planet at all. 8 9 Venus and Earth are very similar in terms of size and mass. Venus Venus is the second planet from the Sun. It is the brightest of all the planets and can be seen from Earth with the naked eye. 12,104km The temperature on Venus is so hot that diameter 465oC probes sent by scientists can only last of Venus 2 or 3 hours before they are destroyed by the heat. Venus has an extremely dense atmosphere that traps heat Venus from the Sun. Temperatures on Venus can reach as high as 465oC, making it the hottest planet in the Solar System. It takes Venus Atmosphere 225 Earth days to orbit around Trapped heat from the sun the Sun. The surface of the planet is extremely dry and is covered in craters, mountains and volcanoes, some of which are active today. The planet Venus is named after the Roman Venus is 108 million km goddess of love from the Sun. and beauty. 10 11 The Earth is constantly spinning on its axis and does one full rotation every 24 hours. This is why we have night and day. Ear th Earth is the third planet from America in daylight Europe in daylight the Sun and is believed to be the only planet in the Solar System that can support life. Earth is the largest of the terrestrial planets. 27 The Earth has one moon. It takes the Inner Core days moon 27 days to Outer Core complete a full orbit of the Earth.

Earth was formed around 4.5 billion years ago. 12 13 It takes Mars 686 Earth days to orbit the Sun. Mars is the second most hospitable planet after Earth. Space missions are being planned and undertaken to increase Mars our understanding of Mars. The average temperature on Mars is -55oC. Mars is the fourth planet from the Sun. It is often referred to as ‘the red planet’ because of its red appearance. The diameter 227.9m of Mars is 6,779 km. It is approximately Mars is 227.9 million 6 times smaller km from the Sun. than Earth. Mars has clouds and wind, just like Earth. At times, the wind can blow Mars is the dust on the surface into a storm named after so big that it covers the entire planet! the Roman The surface of Mars is dry god of war. and dusty. There are craters, canyons, volcanoes and mountains covering it. 27 km Mars is home to the biggest volcano in the Solar System, called Olympus Mons. It is 27 km high and three times the size of Mount Everest. Mt Everest Olympus Mons 14 15 Jupiter spins faster than any other planet. It completes a full rotation in just under 10 hours. It takes Jupiter 4,330 Earth days to orbit the Sun. Jupiter 365 Days Jupiter is the fifth planet from the Sun and is the biggest planet in the Solar System. 4,330 Days 139,822 km Jupiter has over 60 known moons. Jupiter’s largest moon is also Jupiter is 2.5 the largest moon in the entire Solar System – it is called Ganymede. times bigger than all of the other planets in the Solar System put together. More than 1000 Earths would fit inside Jupiter. Jupiter is a gas planet. Its atmosphere is made mostly out of hydrogen and helium gas and the surface is covered in thick clouds. Jupiter has narrow rings that are made out of dust and small pieces of rock. The Great Red Spot is a storm similar to a hurricane that appeared on Jupiter around 400 years ago. The storm is large enough to be viewed from Earth with a telescope. 16 17 Saturn completes an orbit of the Sun every 10,755 Earth days. Earth’s orbit of the Sun Saturn’s orbit of the Sun Saturn Saturn travels at an average speed of 13,445 km per hour. That’s 400 times faster than a jumbo jet. Saturn is the sixth planet from the Sun and is the second largest planet in the Solar System. It is the furthest planet from Earth that can be seen with the naked eye. Saturn has over 60 moons, the largest of Saturn is known for its impressive rings, which which is called Titan. are mostly made out of billions of pieces of ice, dust and rocks. The rings were first discovered Saturn is spinning on an axis, by Galileo Galilei over 400 years ago and just like Earth, meaning that stretch more than 12,700km from the planet. it too experiences seasons.
