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.
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.
Write down Uranus's day measured in Earth days.
Neptune is about the size of Uranus and is known for supersonic strong winds.
Neptune is far out and cold.
The planet is more than 30 times as far from the sun as Earth.
Neptune was the first planet predicted to exist by using math, before it was visually detected. Neptune is about 17 times as massive as Earth and has a rocky core.
Neptune has thirteen moons that we know of and one more waiting for confirmation.
The largest moon is slightly smaller than Earth's Moon and has active volcanoes which erupt like geysers and eject nitrogen frost over the surface.
Name this moon and at least 4 others.
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.
How long does it take for Mars to go around the sun?
Earth is a water world, with two-thirds of the planet covered by oceans.
It's the only world known to harbor life.
Earth's atmosphere is rich in nitrogen and oxygen.
Its name originates from 'Die Erde,' the German word for 'the ground.'
Earth may once have had two moons, nowadays it has just one.
A planet's day is the time it takes the planet to rotate or spin once on its axis.
Write down the Earth's day in hours.
Our Solar System has eight “official” planets which orbit the Sun.
Each planet is at a different distance from the sun. Name its position.
