Use planetary orbits and scale ratios to draw scale solar system orbits while exploring gravitational forces.

The Solar System is a fascinating place, with each planet orbiting the Sun at its own unique distance. But how far apart are these planets, and how do they travel through space? Uncover the true ...

Most planet-forming disks have warps that can lead to planets on inclined orbits, which could explain where the tilt of Earth ...

Celestial mechanics remains crucial in unraveling the mysteries of our inner solar system’s past.

The strange orbits of some objects in the farthest reaches of our solar system, hypothesized by some astronomers to be shaped by an unknown ninth planet, can instead be explained by the combined ...

All planetary systems have a barycenter, a point where their mass is balanced. In the Earth-moon system, this is just below Earth's surface.

The enormous visitor to our solar system may have been about 8 times the mass of Jupiter, and come nearly as close to the sun as the orbit of Mars.

A massive interstellar object passing through our solar system during its formative years likely altered the orbits of planets into trajectories observed today, a new study says.
