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

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

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

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.

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 ...
