The Solar System is the gravitationally bound system of the Sun and the objects that orbit it, either directly or indirectly. Of the objects that orbit the Sun directly, the largest are the eight planets, with the remainder being smaller objects, the dwarf planets, and small Solar System bodies.
Saturn is known most for its rings.
Galileo Galilei first thought it was an object with three parts: a planet and two large moons on either side.
Not knowing he was seeing a planet with rings, the stumped astronomer entered a small drawing — a symbol with one large circle and two smaller ones — in his notebook.
The rings are made of ice and rock and scientists are not yet sure how they formed. The gaseous planet is mostly hydrogen and helium.
Saturn has over 150 moons and satellites. However, of these vast numbers of moons, only 62 are known and confirmed as moons.
Name at least 5 of these moons.
How long does it take for Saturn to go around the sun?
A planet's day is the time it takes the planet to rotate or spin once on its axis.
Write down Saturn's day measured in Earth days.

Mars is a cold, desert-like place covered in dust. This dust is made of iron oxides, giving the planet its iconic red hue.
Mars shares similarities with Earth: It is rocky, has mountains, valleys and canyons, and storm systems ranging from localized tornado-like dust devils to planet-engulfing dust storms.
Mars has two small moons.
Name these moons.

Our Solar System has eight “official” planets which orbit the Sun.
Each planet is at a different distance from the sun. Name its position.
