The Sun is one out of billions of stars and the Sun is the closest star to Earth. The Sun is now a middle-aged star, meaning it is at about the middle of its life. The Sun formed over 4.5 billion years ago. You may think the Sun will die soon, but it will keep shining for at least another five billion years. The Sun’s diameter is about 870,000 miles wideand Fun Fact Did you know 109 times wider than the Earth. The sun Mercury has no atmosphere which is also 333,000 times heavier than the means there is no wind or weather to Earth. This means if you put the Sun speak of. on a scale, you would need 333,000 objects that weigh as much as the Earth on the other side to make it balance. Mercury is the closest to the sun and it is 58,000,000km away from the sun. Mercury also has a diameter of 4,880km. On this planet there are no moons and only one half of the planet sees the sun. The side of Mercury facing the Sun can get up Fun Fact to 426 degrees Celsius. Did you know Mercury has no atmosphere which means there is no wind or weather to speak of. Most people think that Mercury is the hottest planet in the solar system, but thinking that is not write. Mercury isn’t the hottest planet in the Solar System, Venus is and here is why. Unlike Mercury, Venus is covered in a thick atmosphere that traps the Suns’ heat like a greenhouse. Venus is Fun fact 107,826,050 km away from the Did you know Venus and Mercury are the only planets in the sun and it has a diameter of solar system without a moon. 12,000km. Venus is 460 degrees Celsius. Venus is also 4.5 billion years old. Earth is149,669,000km away from the sun and has a diameter of 12,755km. Earth has 1 moon and the temperature on Earth is -89 degrees Celsius to 71 degrees Celsius. Earth is te 5th largest planet in the solar system being bigger than Venus, Mercury and Mars. Fact Not including Pluto because of Did youFunknow Earth is the only planet in it now being a Dwarf Planet. the solar system known to have life. The Moon is the Earth’s only natural satellite and was formed 4.6 billion years. The Moon always has the same side of it’s surface facing the Earth. The first mission to the Moon was in 1959 by the Soviet Lunar. He was also American. Fun Fact Did you know the Moon orbits the Earth every 27.3 days. Out of all the planets in the Solar System (apart from Earth), Mars is the one that people believe is most likely to contain or to have contained life. The largest volcano in the Solar System is on Mars. It is called Olympus Moons. Mars is believed to have had water flowing around it, like Earth once. It may have had a blue sky too. However, it is Fun Fact Mars is the closest unlikely that it had grass, Planet to Earth trees and plants like Earth has now. Jupiter has a liquid metal ocean (metallic hydrogen) at its centre, surrounded by thousands of kilometres of hydrogen and helium gas. Jupiter has a thin set of rings, hardly visible, even with telescopes, from Earth. Jupiter takes only 9 hours and 55 minutes to spin on its axis. This means a day on Jupiter is less than 10 hours long. Its fast Fun Fact Jupiter is the largest rotation causes the planet planet in our Solar system. to be squashed, being wider at the equator than from North to South. Saturn is 1,427,500,000km away from the sun and has a diameter of 120,665km. This planet is 4.5billion years old. It has a 60 moons and the highest clouds can get up to -150 degrees Celsius. The core of Saturn can get up to 11,700 degrees Celsius. Fun Fact Did you know Saturn is the only planet in our solar system with visible rings. Uranus has 27 moons. Ten of these were discovered in 1986. Uranus was the first (Not including Earth) planet in the Solar System. Almost all of the moons of Uranus are named after characters in plays written by Shakespeare. The two moons of Uranus that are not named after Shakespeareare characters (Arlel Fun Fact Uranus was the first planet and Umbriel) are Named after discovered by telescope. characters in a book called "The Rape of the Lock« . At first, Neptune was only the god of water, but later on this was extended to include the sea when he became associated with the Greek god Poseidon. The planet Neptune was discovered in 1846.. Neptune's atmosphere is made up of hydrogen, helium and methane. The methane in Neptune's upper atmosphere. Fun Fact Neptune is a large planet, nearly four times the size of Earth. Pluto isn’ t a planet any more, but it’s still a very interesting “dwarf planet” in the Solar System. You might have heard that Pluto has a large moon called Charon , but did you know that it actually has 3 moons in total. Charon is the large one, with a mass of half that of Pluto’s. If you think Pluto is named after a Disney character, you’re wrong. It’s actually named Fun Fact after the Roman god of the In 2006 Pluto was demoted to the status underworld. of dwarf planet. Yes No
