Our solar system

Earth: Earth is composed of two-thirds water and one-third land. As far as we know, this is the only planet where life is possible.

Venus: Venus is located in the 2nd row towards the Sun, at a distance of just over 108 million kilometers from the Sun.

Mars: The rocks on Mars contain a lot of iron. The iron has oxidized, causing it to rust. Rusty iron has a red-brown color, which is why Mars has its red appearance.

Uranus: On a clear night, you can see Uranus from Earth.

Jupiter: Earth fits into Jupiter approximately 1300 times, but because it is mainly composed of light gases, the planet weighs only 318 times as much as the Earth.

Saturn: Saturn, the second-largest planet in our solar system and the sixth one from the Sun, is the farthest planet that we can see without a telescope.

Neptune: It is located at about 4.5 billion kilometers from the Sun, which causes freezing temperatures of around -200 degrees Celsius.

Pluto: Pluto was originally considered a full-fledged planet, but it was reclassified as a dwarf planet in 2006.

Sun: The sun is not a planet but a star, a burning gas sphere. Its radiation makes life on our Earth possible. It is also the closest star to Earth.

Mercury: The planet Mercury is named after the Roman god of trade and profit. Mercury is the smallest planet.

What would space sound like? It is certainly not quiet! Researchers have collected sounds from planets. And they sound a bit scary...
