The planets orbit the sun in elliptical paths, with the inner four being rocky terrestrial worlds and the outer four being gas and ice giants many times larger than Earth. Our fascination with ...

For the dwarf planet candidate, one trip around the sun takes over 24,000 years. Its orbit challenges a proposed path for a hypothetical Planet Nine.

Ever wonder why all the planets orbit the Sun on more or less the same plane? It’s not coincidence—it’s cosmic physics. This video breaks down how a spinning cloud of gas and dust became the ...

Simulations show that the stars’ tug could send Mercury, Venus or Mars crashing into Earth — or let Jupiter eject our world from the solar system.

On Earth, depending on where you are, the analemma can be at different angles, though it always traces out this figure-of-eight pattern. But on other planets, with their own orbits and mean solar ...

These findings can answer as to why some planetary paths have ... most agree that the orbit of the planets should be in circles that are arranged concentrically around the sun and lie on the ...

How does a planet’s size influence its orbit around its parent star ... system exhibit largely circular orbits around our Sun, astronomers continue to discover exoplanets whose orbits are largely ...

It actually follows its own tiny elliptical orbit around what is called the center of gravity (the barycenter) of the system, the sun and the orbiting planets ... in this path can be traced ...

Earth’s tilt is what causes the seasons; in the summer, when our planet’s pole is tipped toward the sun, the days are longer, ...

The culprit for all of these elliptical orbits is gravity. “All the planets tend ... meaning its path around the sun is becoming more circular. If our planetary orbit were a perfect circle, ...
