Every planet in the solar system is affected by multiple forces. The gravity of the Sun pulls planets toward the center of the solar system. The inertia from the creation of the planets sent them ...

NASA’s Jet Propulsion Laboratory in La Cañada Flintridge, for example, has created a detailed model of the solar system that uses Albert Einstein’s general relativity theory of gravity to ...

A new probe in development known as GIRO represents a low-cost step toward unlocking the secrets of exoplanets, all through ...

In 2009, a pair of astronomers at the Paris Observatory announced a startling discovery. After building a detailed computational model of our solar system, they ran thousands of numerical simulations, ...

Stars passing close to the sun could cause planets to collide, including with Earth, or even be ejected as rogue planets, new ...

The newest example of a resonant chain is the HD 110067 system. It’s about 100 light years away and has six sub-Neptune planets, a common type of exoplanet , with orbit ratios of 54:36:24:16:12:9.

Deviations from Einstein gravity are constrained by solar system experiments, the recent observations of gravitational waves and the near-horizon images of black holes. There is now a large literature ...

Objects at the far reaches of the solar system behave as if they are being pulled around by an object that we cannot see, which is probably another planet, they suggest.

This novel model challenges existing notions of how the solar system came to look the way it does today.. The solar system's giant planets are famous for their many moons. Saturn currently leads ...
