Mercury: The smallest planet in the Solar System
Mercury can only be seen at dawn or sunset. Mercury has no natural satellites, and also has no atmosphere. The planet Mercury is the smallest planet in the solar system with a diameter of 4878 km. Its rotation is very slow, the planet is only making three full rotations in twice revolves around the sun. That’s why one side of Mercury is very hot while the other side is very cold. Temperature reaches 4300 ° C on the part facing the sun, and -2200 ° C at the back to the sun. Because Mercury has no atmosphere, it makes a large temperature difference.
Venus: The Sunrise happens at the West and The Sunset happens at the East
Venus is a very bright planet. Venus is called the morning star and evening star, because the planet is visible in the east as the morning and in the west as twilight. Venus is also called a white planet because its light is white. Venus is almost as large as the earth.
Venus rotation direction is opposite from the direction of other planets rotation, so the sunrise is at the west and the sunset is at the east. In addition, the rotation period of Venus is longer than the period of the revolution around the sun.
Venus's atmosphere is thick and always veiled by clouds. Because of that, so planet Venus becomes the hottest planet in the solar system with temperature of 462°C. Venus does not have a satellite.
Earth: Planet of Life
Planet Earth is the largest of the four terrestrial planets. And Earth also has the highest density, the largest surface gravity, strongest magnetic field, and rapid rotation. Earth is also the only terrestrial planet that has an active tectonics plate. Earth’s atmosphere and the magnetic field protect the Earth's surface from the solar wind, ultraviolet light, and radiation from outer space. Planet Earth is the only planet that supports life.
Mars: Human Face on the Plain of Mars
On Mars, there is a unique feature in the Cydonia Mensae region. This feature is a hill that when viewed from above appears as a human face. Some people regarded it as an evidence of a long extinction of civilization on Mars, but in the present, it has been shown that the feature is just an ordinary natural appearance.
Jupiter: Planet with Greatest Storms
Jupiter is the largest planet in our solar system. This planet is about 318 times the size of Earth. Jupiter has 63 satellites. Jupiter is a gas planet with no land. EVERYTHING in there is GAS with extremely cold temperatures.
Jupiter has a large red spots that is called The Great Red Spot, this is like a hurricane storm that could hit areas of 40,000 km in length and width is 4000 km.
Saturn: lighter than water
Saturn has a low density because most of the constituent substances are in the form of gases and liquids. Among the planets in the solar system, Saturn is the only planet that its density is lighter than water.
Saturn has 59 moons. Saturn's core consists of solid rock. Saturn's atmosphere is composed of ammonia and methane gas.
Uranus: the coldest atmosphere in the Solar System
The form of the planet Uranus is similar to the surface of the Moon with green and blue color. Uranus's atmosphere contains lots of "ice", ammonia, and methane. Its atmosphere is the coldest atmosphere in the Solar System, with the lowest temperature of 49 K (-224 ° C).
Neptune: The Farthest Planet
Neptune is the farthest planet (eighth) when viewed from the Sun. Planet's rotation period is 16.1 hours, while the revolution period is 164.8 years. Neptune has 8 satellites. Neptune has greenish color.
