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.
Uranus is an oddball. It has clouds made of hydrogen sulfide, the same chemical that makes rotten eggs smell so foul.
It rotates from east to west like Venus. Its tilt causes extreme seasons that last 20-plus years, and the sun beats down on one pole or the other for 84 Earth-years at a time.
Methane in the atmosphere gives Uranus its blue-green tint. It also has 13 sets of faint rings.
Uranus has 27 moons that we know of. Five of the moons are large and the rest are much smaller.
Name these 5 moons.
How long does it take for Uranus to go around the sun?
A planet's day is the time it takes the planet to rotate or spin once on its axis.

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.

Venus is Earth's twin in size and has no moons.
Its surface has various mountains and volcanoes. Because of its thick, toxic atmosphere that's made of sulfuric acid clouds, Venus is an extreme example of the greenhouse effect. The average temperature on Venus' surface is 900 F (465 C).
Venus spins slowly from east to west, the opposite direction to most of the other planets.
The Greeks believed Venus was two different objects — one in the morning sky and another in the evening. Because it is often brighter than any other object in the sky, Venus has generated many UFO reports.

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