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

You’ll have to assume that the orbits you want to travel between are circular (most solar system orbits are at least a little elliptical) and that they travel around our the sun on the same flat plane ...

Astronomers have detected an interstellar object approaching our solar system.; Called "2I/Borisov" (formerly "C/2019 Q4" or "gb00234"), the object appears to be following a path originating from ...

Their elliptical orbits, for example, ... And its orbit must be inclined to the plane of the solar system by between 15 and 25 degrees. Given that level of detail, ...

Using computer simulations of the solar system with a Planet Nine, Batygin and Brown also showed that there should be even more objects tilted a whopping 90 degrees with respect to the solar plane.

Until now, every image of the sun has been taken from straight on, along the 'elliptical plane' - the flat disk on which all planets orbit. But by tilting its orbit to 17 degrees below the equator ...

All of them have elliptical orbits pointing in the same direction, ... These things have been twisted out of the solar system plane with help from Planet Nine and then scattered inward by Neptune." ...

There are dozens of enormous armless galaxy clusters called elliptical galaxies in the Plane, but not nearly as many disk-shaped galaxies with spiral arms. An elliptical galaxy (left) and a spiral ...

Bad news, earthlings. Computer simulations of the solar system’s future reveal a new risk facing us all: The gravitational tug of a passing star could either cause another planet to smack into ...
