The scheme includes the Sun, the world (where you’re now!), and every one of the opposite planets, asteroids, and comets that go around and around it.

You may suppose that the world could be a pretty massive place, however, the world isn’t even the most important planet within the scheme. the most important planet is Jupiter – you may work one,321 piles of earth within Jupiter. The Sun is even larger than Jupiter – it might take one.3 million planets the dimensions of Earth to fill constant volume because of the Sun.

Everything within the scheme revolves around the Sun. The Sun could be a star – an enormous ball of hot gas that provides lightweight warmth. There area unit eight planets that orbit around the Sun. The nearest planet to the Sun is Mercury, and therefore the farthest away is Neptune. The biggest planet is Jupiter, and therefore the smallest planet is Mercury. The Earth is the sole planet that we all know has creatures living on that. The Earth rotates because it orbits the Sun. It takes some unspecified time in the future to finish a rotation. It takes one year for the world to finish one circuit around the Sun. we have a tendency to decisions this year. The Sun is simply one among the many billions of stars within the galaxy that we have a tendency to sleep in, which is termed the galaxy. the total Universe has a minimum of one hundred billion galaxies in it. You are commanded onto the surface of the world by a force referred to as gravity. this can be the constant force that keeps the world and therefore the alternative planets orbiting around the Sun. Not everything within the scheme orbits directly around the Sun. The Moon orbits around the Earth.

The planets:
Mercury – is the nearest planet to the Sun. it’s the tiniest planet and is created of rock. it’s therefore about to the Sun that it solely takes eighty-eight days for it to finish its orbit and is far hotter than Earth.

Venus 

Venus is the next planet from the Sun when Mercury. it’s a conjointly a product of rock. Like Earth, Venus has an environment (air) around it, however, it’s loads thicker than Earth’s and Venus is for good coated in clouds. Venus is the hottest planet and has a mean temperature of 460°C. it’s concerning the constant size of Earth. It takes 225 days to travel around the Sun.

Earth

this can be wherever we have a tendency to live! Earth is created of rock and is the sole planet wherever water is liquid. the opposite planet’s area unit is either too hot or too cold. Earth takes one year to travel around the Sun.

Mars 

Mars could be a very little smaller than Earth, however, loads additional out. It wont to have an environment like Earth and Venus, however it doesn’t have abundantly any longer. Mars is chromatic in color and is typically referred to as ‘The Red Planet’. Mars takes 687 days to finish its orbit of the Sun and therefore the average temperature is -63°C.

Jupiter

Jupiter is the largest planet within the scheme. you may work one,321 piles of earth within Jupiter. it’s a product of gas and is one of the four ‘gas giants’. Jupiter has sixty-six moons; one among them, Ganymede, is larger than Mercury. Jupiter is 5 times as off from the Sun as the Earth is and takes virtually twelve years to travel around the Sun.

Saturn

Saturn is legendary for its rings. The rings were initially determined (with a telescope) in 1610 by Galileo Galilei and the area unit was created of large numbers of little lumps of ice and mud (mostly ice). The items within the rings are also as little as a metric linear unit or as giant as a number of meters across. Saturn is the second-largest planet within the scheme and is another one among the ‘gas giants’ like Jupiter. It takes twenty-nine. 5 years to travel around the Sun.

Uranus

Uranus is another of the ‘gas giants’. you may work sixty-three planets the dimensions of Earth within Uranus. Uranus takes eighty-four years to orbit the Sun and is the coldest planet, with a mean temperature of -220°C.

Neptune

Neptune is the farthest planet from the Sun. it’s thirty times as off from the sun as Earth and takes a hundred sixty-five years to travel around the Sun. Neptune is the last of the four ‘gas giants’ and is fifty-eight times the amount of Earth.
