Narrator: Black holes are some of the most ... Brown noticed that some of them have highly unusual orbits. While most objects in our solar system orbit the same plane, and in the same direction ...

This may explain the strange properties of the orbits of our solar system's planets, which are not quite perfectly circular, and all lie on slightly different planes. NASA artist’s conception of ...

A new study claims it is possible an "alien visitor" could have warped our solar system during its earliest years.

An object eight times the mass of Jupiter may have swooped around the sun, coming superclose to Mars' present-day orbit ...

Ever since Isaac Newton famously talked about gravity, its dominance as a force in our solar system has been well known. It's ...

When you first learned about the Solar System, you probably saw diagrams that made it look orderly, with planets arranged in circular orbits around the Sun on a flat disk. But in reality, our Solar ...

An interstellar visitor may have warped the solar system billions of years ago, a new study has claimed. Scientists suggested the enormous object disrupted the orbits of Jupiter, Saturn ...

Since the formation of the Solar System, the orbits of the planets have evolved and changed over time. While one of the most prominent ideas in the last few decades is planetary migrations and the ...

“We predict the existence of an Earth-like planet and several TNOs on peculiar orbits in the outer solar system,” write the authors, Patryk Sofia Lykawka of Kindai University, Japan and ...

The Sun is the largest object in the Solar System. The Sun's huge gravitational ... for example, Mercury orbits once every 88 Earth days, but Neptune orbits once every 165 Earth years For a ...

Astronomers have sent artificial satellites (satellites that are manmade) to orbit several Solar System objects, including Jupiter, the asteroid Vesta and Mars. Polar orbits take the satellites ...

"That's when we started thinking about the very precisely measured orbits of objects in the solar system." In principle, a primordial black hole's gravitational pull "could produce wobbles in the ...
