Researchers based at Aarhus University measured the orbital eccentricity of 74 small extrasolar planets and found their orbits to be close to circular, similar to the planets in the solar system, but ...

Studying the orbits of thousands of exoplanets shows that large planets tend to have elliptical orbits, while smaller planets tend to have more circular orbits. This split coincides with several other ...

Viewed from above, our solar system's planetary orbits around the sun resemble rings around a bulls-eye. Each planet, including Earth, keeps to a roughly circular path, always maintaining the same ...

In this video, we dive deep into the concept of circular orbits within the Three-Body Problem. Explore how gravity, motion, and complex interactions between three celestial bodies create fascinating ...

The Solar System is remarkably regular, its eight planets orbiting the Sun in the same direction in very nearly circular trajectories. Their orbits lie nearly in the same plane, which is aligned with ...

If you’re looking for life beyond the solar system, there’s strength in numbers. A new study suggests that systems with multiple planets tend to have rounder orbits than those with just one, ...

The planets of our solar system move in ellipses. We've known this, so we are told, ever since Johannes Kepler devised his laws of planetary motion in the early 1600s. While it's true that orbits are ...

Though wildly different in so many ways, Earth and Saturn's moon Titan have something important in common. Among all the objects in the solar system, they're the only two with liquids on their ...
