     T.: Now we are going to read and translate the text.
Outer planets of the Solar System

Our solar system is made up the sun, eight planets, more than 150 moons, as well as comets, asteroids, dwarf planets and other space rocks.
Planets, asteroids and comets orbit the sun. They travel around our sun in an ellipse. It takes Mercury, the nearest planet, only 88 days but Neptune 164 years to travel around the sun once.
Moons  orbit planets. Currently, Jupiter has the most moons – over 60. Mercury and Venus don't have any moons.
The inner planets Mercury, Venus, the Earth and Mars are called  terrestrial planets. This means they have a hard  surface to stand on. Jupiter, Saturn, Neptune and Uranus are the outer planets. They are also called the gas giants because you can't stand on them - their  surface is made of gas.
There are many theories on how the solar system  developed. About 4.5  billion years ago a big  cloud of gas and  dust probably  collapsed. The sun formed in the middle, the  densest region. Further away from the sun, gases changed to planets made of rock.


The planets of our solar system 

Jupiter

 Jupiter is the fifth planet from the sun and the largest in our solar system. It has 1 400 times the  volume of our Earth, but is only 300 times as  heavy because the planet must be made up of gas rather than rocks or metal.
completes one full turn every 10 hours. If you look at Jupiter closely, you can see stripes , probably clouds that are  created by fast-moving winds.
Saturn 
Saturn is the sixth planet from the sun and the second-largest in our solar system. It is different from the other planets because of its rings, which were first seen by the Italian astronomer Galileo in 1610.
You can see Saturn without using a telescope, but you need one if you want to see its rings. Saturn has a diameter about 10 times larger than the Earth and about 760 Earths could fit into the planet.
Uranus
Uranus is the seventh planet from the sun. It is sixth in size and just visible to the human eye. It was  discovered by accident by the British  astronomer William Herschel in the 18th century.
Uranus has a diameter of over 50,000 km - about 4 times that of the Earth and it is 3 billion km away from the sun. It takes Uranus 84 years for one single orbit around the sun and 17 hours for one  rotation around its  axis. The unusual thing about Uranus is that its poles are  pointed directly at the sun. This means that it orbits the sun on its side. Each pole gets 42 years of sunlight and then 42 years of darkness.
Neptune 
When Neptune was discovered 1846 astronomers thought it was a star. It is the eighth planet from the sun. It does not shine so brightly, so it is only visible when you use a telescope. It appears as a green - bluish disc, like Uranus.
 It takes Neptune, which is almost 4.5 billion km away from Earth, almost 165 years to travel around the sun once. Neptune's day is shorter than an Earth day - only 16 hours.
