The first five planets are named after Roman gods. The inner solar system contains the Sun, Mercury, Venus, Earth and Mars. C | 6. It formed by gravity in a large molecular cloud. Exploring the Solar System – Ian Ridpath! For the Earth, this journey is 365.25 days long, but for a faraway planet like Neptune, it takes 165 years. Because it is small and different from other planets, it is considered to be one of the five "dwarf" planets, but not everyone supports this opinion. C | 20. Sun There are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. ! Pluto has an orbital speed of 5 km per second. Four largest ones were discovered by Galileo Galilei, an Italian astronomer, in 1610.
In Roman mythology, Saturn is a version of the Greek God Cronos, Zeus' father and god of agriculture. The Solar System formed 4.6 billion years ago from the gravitational collapse of a giant interstellar molecular cloud.The vast majority of the system's mass is in the Sun, with the majority of the remaining mass contained in Jupiter.The four smaller inner planets, Mercury, Venus, Earth and Mars, are terrestrial planets, being primarily composed of rock and metal. This planet is recognizable by its system of seven shining rings which circle the equator, the line which is half-distance between two poles. The Solar System is made up of all the planets that orbit our Sun. At that time, it was believed that Neptune was the furthest planet in the solar system, watching over the "sea" that we called the space. Water on Mars has been frozen into rocks, so there is a suspicion there could be primitive life forms on this planet. Beyond Mars is the asteroid belt – a region populated by millions of rocky objects.
The smallest of them, called Europa, is covered in ice, so scientists believe this satellite may support some life forms. In 1930, it was spotted by a US astronomer Clyde Tombaugh. B | 19.

This system contains nine planets—Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto. 7/22. The main asteroid belt lies between the orbits of Mars and Jupiter. Because it is so close to the Sun, Mercury is a really hot planet. Because the Sun is so large, its powerful gravity attracts all the other objects in the Solar System towards it. Until recently, the furthest known planet was an icy world called Pluto. In 2006, the International Astronomical Union decided that Pluto and Eris must be classed as “dwarf planets”. There are nine planets in the Solar System, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and. The solar system is port of the Milky Way galaxy which is a barred-spiral galaxy.

This system contains nine planets—Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto. A | 23.
Apart from the Sun, the largest members of the Solar System are the eight major planets. However, at night, the planet cools down quickly, and the temperature drops to – 290 °F (-180°C). However, Pluto is dwarfed by Earth’s Moon and many astronomers think it is too small to be called a true planet. Most of them were named after Titans, brothers and sisters of Saturn in Greek mythology. It can sometimes be seen from Earth.This is a rocky planet with very thick clouds which prevent us from seeing its surface.
