Though 3I/ATLAS will never come close to Earth, its passage offers a rare chance to study material beyond our solar system ...

Only one of the 20 known asteroids has an orbital eccentricity below 0.38. This makes sense since asteroids with wider orbits come closer to Earth and are easier to detect.

This new planet, however, has an almost unheard of orbital eccentricity of 0.94. To put it in terms of our solar system, NOIRLab explains that if this planet orbited the sun then it would come 10 ...

As the closest planet to the Sun, Mercury is exposed to the star's enormous gravitational field. And it's really stressful.

For comparison, Earth's orbit has an eccentricity of 0.0167 and is therefore close to circular; at the other extreme, an orbital eccentricity of 1 would be parabolic.

Saturn's moon Mimas could have grown a huge underground ocean as its orbital eccentricity decreased to its present value and caused its icy shell to melt and thin. April 15, 2024. 0.

Earth’s orbit around the Sun is not circular, but an ellipse that is slightly elongated with an eccentricity of 0.017. (An eccentricity of 0 is a circle, while the dwarf planet Pluto has a ...

Earth's orbital eccentricity — the amount by which the circle it draws around the sun is flattened — is strongly affected by the orbits of the solar system's giant planets, Jupiter, Saturn ...

Talk about star power! Stellar Encounter. A passing star which blew past our solar system nearly 3 million years ago could have altered the Earth's orbit, researchers found.
