Discover more about Planet Earth.
Narrator: 4 and a half billion years ago, clouds of cosmic dust and gas which were orbiting the Sun collided into one another, creating the Earth,
our planet, the home of mankind.
It spins at 1000 miles an hour, taking 24 hours to complete a full rotation.
Relentlessly travelling through space, it undertakes a full orbit of the Sun every year, giving the planet its seasons.
In fact, the definition of a planet is a celestial body which orbits around a star.
The moon, is only a quarter the size of the Earth.
Gravity holds it in an ongoing embrace, its orbit taking nearly 27 and a half days to complete.
What's this鈥?
Stella: The Earth is spinning around, its rotation causes night and day鈥
It鈥檚 daytime when it faces the Sun,
Night-time when it faces away.
The Earth is spinning around,
Its rotation causes night and day鈥
Now the moon doesn鈥檛 spin,
While it orbits the Earth
Gravity stops it drifting awwwwaaaaaay鈥
