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 ...

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.

Orbital eccentricity . The shape of Earth's orbit is known as eccentricity. (Image credit: NASA/JPL-Caltech) Among the planets of the solar system, Earth's orbit is among the most circular.

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 ...
