A new astronomical study suggests that Earth could one day be ejected from the solar system, not by the aging of the Sun, but by the unpredictable trajectory of a rogue star. While such a scenario ...

Astronomers believe that this increasing eccentricity could destabilize Mercury’s orbit, potentially leading ... With passing stars, Pluto has a 3.9% chance of being ejected from the solar ...

"Meanwhile, its perihelion – the closest point on its orbit to the Sun – is 44.5 times that of the Earth’s orbit, similar to Pluto's orbit ... "Its high eccentricity suggests that it ...

But then scientists at the International Astronomical Union decided Pluto didn’t quite make the cut, it lacked the gravitational muscle to clear its orbit. Ouch. Now officially labeled a ...

For decades, it captivated imaginations with its icy surface and distant orbit beyond Neptune. But in 2006, Pluto’s planetary reign came to an end when the International Astronomical Union ...

Still that date will be one to circle on cosmic calendars. It takes Pluto slightly over 248 Earth years to orbit the sun, which means that on March 23, 2178, one Plutonian year will have elapsed ...

The International Astronomical Union reclassified Pluto as a dwarf planet because it does not clear its orbit of other debris. Pluto was the little planet that could — until it couldn’t.

Pluto’s orbit is arduously long ... Aquarius is about innovation, humanitarian efforts, community, eccentricity, and authenticity. If you haven’t felt it already, we’ll start to see ...

Pluto and its moon Charon may have been briefly locked together in a cosmic “kiss”, before the dwarf planet released the smaller body and recaptured it in its orbit. Charon is the largest of ...

In 1905, he suggested these were caused by the pull of another unknown planet, and made predictions as to its orbit. Based on the predictions from Lowell and other astronomers, Pluto was ...

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 ...
