Most of the major planets – all except Mercury and Venus – have moons. Pluto and some other dwarf planets, as well as many asteroids, also have small moons. Saturn and Jupiter have the most moons, with dozens orbiting each of the two giant planets. Moons come in many shapes, sizes, ...

While we have made significant progress in understanding gravity, it remains a fascinating and somewhat mysterious phenomenon. Whether it is the force that keeps us grounded, the reason planets orbit the sun, or the subject of groundbreaking scientific theories, gravity is a fundamental force that ...
Phobos is a low-gravity body.A single jump could send an astronaut 12 stories high, and make her wait 12 minutes until landing. (Deimos, the other moon of Mars, is smaller and has even less gravity.) Could you jump into orbit on Phobos?
This occurs as a result of the planet's gravity, and also because of the effects of its magnetic field. Now, if material from Saturn's rings is being lost and nothing new is added from time to time, the rings would be disappearing. ...

Gravity is the reason things with mass or energy are attracted to each other. It is why apples fall toward the ground and planets orbit stars. Magnets attract some types of metals, but they can also push other magnets away. So how come you feel only the pull of gravity? In 1915, Alber...
The perihelions of all planets precess, which can mostly be explained by Isaac Newton's theory of gravity as a result of the pull of all other planets and moons in the solar system on one another, according to the Berkeley Lab. There is, however, one exception that gave astronomers a ...
On other planets, gravity has a different value, so a mass on Earth, while having exactly the same mass on other planets, would have a different weight. A 68 kg person on Earth would weigh 26 kg on Mars and 159 kg on Jupiter. ...
