Early in our Solar System’s history, bits of icy debris were scattered and then gradually coaxed into a spiral alignment in ...

Astronomers believe they've discovered a spiral structure inside the Oort cloud that surrounds our solar system.

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 ...

Down here, you'll start to feel pretty lousy, because the sun's gravity is so strong, a 150-pound person on Earth would weigh about 4,000 pounds here. That's nearly the same as a rhino.

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.

Groundbreaking research reveals the Oort Cloud's shape as a spiral structure, challenging traditional beliefs about its random collection. NASA's Plei ...

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 ...
