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

A11pl3Z's eccentricity is now estimated to be near 6.0, the highest seen yet, confirming its hyperbolic orbit.

The discovery of the exoplanet, a super-Earth called Kepler-735c, is all down to something called transit timing variations, ...

A11pI3Z: Astronomers believe fast-moving object A11pI3Z could be only the third known interstellar visitor, after 'Oumuamua ...

Researchers from the Nanjing Institute of Geology and Paleontology of the Chinese Academy of Sciences and Columbia University ...

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 ...

Hycean worlds are also called ocean worlds. They're planets covered in oceans that also have thick hydrogen atmospheres.

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, and the true sun’s daily path across the sky is higher. The opposite is ...

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

Only one of the 20 known asteroids has an orbital eccentricity below 0.38 - with 0 being a perfectly circular orbit and 1 meaning an elliptical or oval-shaped orbit.

The other is Earth’s orbital eccentricity this is basically the fact that our planet’s orbit around the sun is not in a perfect circle but a shape where there is a point when we are closer to ...

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 ...
