But if Earth slows down more gradually, you'd instead suffer a slower (but still horrific) death. That's because the planet is about to get very, very hot. You see, the sun's tremendous gravity ...

transitioned from being affected primarily by Earth's gravity to also being affected by the Sun. At this distance, the contributions of the Sun and Earth to the Moon's orbital precession were ...

For a brief, but exciting, time last year, Earth had two moons. A small asteroid lingered close to our planet in its orbit ...

centered slightly outside of the Sun's radius, as Jupiter makes each orbit. On Earth, we have to contend with our own gravity ...

Large bodies such as the Sun, the Moon and the Earth all have very large masses. Due to the large mass each body has a gravitational field that attracts smaller masses to it. Mass (\(m\)) is a ...

The sun's distance from Earth changes throughout the year but ... own tiny elliptical orbit around what is called the center of gravity (the barycenter) of the system, the sun and the orbiting ...

A new study has revealed that gravity’s effect on Earth is constantly shaping the surface of our planet. When our planet formed, it did so by pulling dust and rock toward its gravitational field.

The visible universe—including Earth, the sun, other stars ... and a force that repels gravity known as dark energy (70 percent). Scientists have not yet observed dark matter directly.
