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

All solar system planets circle our sun with slightly tilted orbits — and a new study shows even distant planetary systems in quiet neighborhoods have orbital tilts, too.

These planets have circular orbits similar to the orbits of planets in our solar system. At least two of the recently detected planets have approximately circular orbits.

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.

Astronomers have discovered six planets orbiting a bright, nearby star in perfect synchrony like a grand cosmic orchestra.

A new study suggests that a close encounter with a massive interstellar object, possibly eight times the mass of Jupiter, may have significantly altered the orbits of the four outer planets in our ...

Scientists have discovered a Solar System 'superhighway' that could lead to faster, more efficient space travel.

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 ...

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