The solar system
The Sun: The sun is the largest object of the solar system. It contains more than 99.8% of the total mass of the solar system(Jupiter contains most of the rest).The sun has nine planets around it: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto.
Mercury: Mercury is the closest planet to the Sun and the eighth largest. In Roman mythology is the god of commerce, travel and thievery, the Roman counterpart of the Greek god Hermes, the messenger of the Gods. The planet probably received this name because it moves so quickly across the sky.Mercury has a small magnetic field whose strength is about 1% of Earth’s. Mercury has no known satellites.
Venus: Venus is the second planet from the Sun and the sixth largest. Venus (Greek: Aphrodite; Babylonian: Ishtar) is the goddess of love and beauty. Venus is sometimes called as Earth’s sister planet. In some ways they are very similar: Venus is only slightly smaller than Earth (95% of Earth’s diameter, 80% of Earth’s mass). Both have few craters indicating relatively young surfaces. Venus has no magnetic field, perhaps because of its slow rotation. Venus has no satellites.
Earth: Earth is the third planet from the Sun and the fifth largest. Earth is the only planet whose English name does not derive from Greek/Roman mythology. The name derives from Old English and Germanic. 71 Percent of the Earth’s surface is covered with water. The Earth is the only planet with water and oxygen. Earth has only one natural satellite, the Moon, but it has lots of artificial satellites made by people.
Mars: Mars is the fourth planet from the Sun and the seventh largest. Mars (Greek: Ares) is the god of War. The planet probably got this name due to its red color; Mars is sometimes referred to as the Red Planet. Mars has a lot of very high mountains, they are higher then Earth’s. Mars has two tiny satellites: Phobos and Deimos. Their weights are 11 and 6 kg.
Jupiter: Jupiter is the fifth planet from the Sun and by far the largest. Jupiter is more than twice as massive as all the other planets combined (318 times Earth). Jupiter (a.k.a. Jove; Greek Zeus) was the King of the Gods, the ruler of Olympus and the patron of the Roman state. Zeus was the son of Cronus (Saturn). It has 63 satellites.
