Ever since Isaac Newton famously talked about gravity, its dominance as a force in our solar system has been well known. It's ...

On top of all this, everything in the solar system is held in place by the Sun's gravity, and so on. Gravity diminishes over ...

Just about everything in our solar system has been captured by the sun’s gravity, which also has a heavy hand in ordering the movements of all those objects. Most comets are thought to originate ...

That's because the planet is about to get very, very hot. You see, the sun's tremendous gravity pulls the Earth right toward it. Meanwhile, the planet is trying to whiz away in this direction.

Gravity keeps all of the planets (including Earth) in orbit around the Sun. It also keeps the Moon in orbit around the Earth. Although every object (including you!) exerts a gravitational pull on ...

The moon does, however, experience changes in its shape and gravity. How the moon responds ... responses of the moon to the Earth and the sun offer clues as to what lies beneath its surface.

It was Johann Kepler, almost exactly 400 years ago, who declared that each planet speeds up as it approaches the Sun in its elliptical orbit, but travels more and more slowly as it heads away. So ...

Gravity also acts between the Moon and the Earth and keeps the Earth in orbit around the Sun. The force that pulls things to the centre of Earth (and other planets) is called gravity. Gravity also ...
