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

What we already know, however, is that it has a much more extreme orbit than the two previous examples, 'Oumuamua and Borisov ...

This week, astronomers spotted the third known interstellar visitor to our Solar System. First detected by the Asteroid ...

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

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 ...

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

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 ...
