THE PLANETS IN THE SOLAR SYSTEM
I learned the following information from an article at this website.
There are two types of planet: the terrestrial planets, which are rocky and have weak magnetic fields and have two moons or less. In order of their position from the Sun they are Mercury, Venus, Earth and Mars. The other type are the gas giants.
Mercury has practically no atmosphere and its surface has craters much like Earth’s moon.
Venus is of similar size to the Earth. It has a very dense atmosphere largely composed of carbon dioxide. Due to the greenhouse effect the temperature on Venus is many hundreds of degrees Kelvin.
Earth has an atmosphere composed of nitrogen. It is cool enough to have liquid water in the form of oceans and lakes. It has one moon.
Mars is smaller and cooler than the Earth. It has a thin atmosphere that is too thin to retain water. It has two moons.
The gas giants are composed of gas, have stronger magnetic fields, and have rings and many moons. In order of their position from the Sun they are: Jupiter, Saturn, Uranus and Neptune.
Jupiter is the largest of all the planets. It is not solid, and so different bands of gas on the surface rotate at different rates. The Great Red Spot of Jupiter is a hurricane that has lasted for over 400 years. It is the size of three Earths. Jupiter has over 63 satellites. The most well-known of these are the Gallilean moons, Callisto, Ganymede, Europa and Io.
Saturn is the next largest planet. It has many distinctive rings around it. The density of Saturn is so light that the entire planet would float on a body of water. Saturn has at least 43 moons.Neptune’s distance from the Sun is thirty times the distance from Earth to the Sun. It has not completed a full orbit even since it was discovered in 1846.
