Our Solar System

 We have eight planets in our solar system.

Their names are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.

The biggest planet is Jupiter, that is an orange planet.

Jupiter is made of gases such as hydrogen, helium, methane, ammonia and traces of water´s vapor.

Mercury is the smallest planet, its grey and it has gases such as helium, sodium and oxygen, with a predominance of the first two.

Uranus is the coldest planet, reaching -224ºC. It´s light blue, and it is made a rocky silicate / iron-nickel core in the center, an ice sheet in the middle and a hydrogen / helium atmosphere.

Venus is the hottest planet,because its proximity of the Sun and it has a dense atmosphere that made it in our solar system's hottest planet.

It´s like orange, and it´s made of mantles of molten rock.

Mars is the most similar with Earth, it´s red, and it´s a rocky planet with a fine atmosphere.

Earth is a blue planet, it is the third closest planet to the Sun. It consists of solid, liquid and gaseous materials, which are arranged in concentric layers.

Saturn is the sixth planet from the Sun and the second largest in the Solar System behind Jupiter. It´s brown/yellow.

It´s made of Helium, hydrogen, ammonia, hydrocarbons, water´s vapor and phosphine.

Neptune is is the eighth planet in the Solar System, the last from the Sun. It´s blue, and it´s made of a mix with silicates and various ices, surrounded by a mantle rich in water, methane and ammonia to which an atmosphere composed of hydrogen, helium and methane is superimposed.

We have images of all of almost planets from the solar system. Mars could be colonizated by the humans, because Mars has water and the Martian day is similar of Earth´s. A solar day on Mars has 24 hours, 39 minutes and 35,244 seconds.

We have images of some planets from our solar system.

We still have a lot to learn about our solar system, but the little we know it´s already spelling us!
