While the Sun is the centre of our solar system, it only makes up about 99.8 per cent of the mass of the entire solar system. So, the Sun's centre is not exactly located on the barycentre of the ...

By studying an alternate version of our own solar system, Simpson and Chen hoped to investigate how exoplanets might influence one another's orbits. Certain orbits of planets, for instance, may make ...

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 ...

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 ...

But that's not the whole story. "Instead, everything orbits the solar system center of mass," James O'Donoghue, a planetary scientist at the Japanese space agency, JAXA, recently explained on Twitter.

And in 2016, astronomers Konstantin Batygin and Mike 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 ...

His conclusion is simple and straightforward and has the ring of truth: the solar system is full of bodies, and some are large, and some are small. Some are in regular orbits, and some are not.

never happened as a result of the fictional world not being real. But researchers have long wondered what the impact might be if another world were to be added to our solar system. In particular ...

Other researchers, such as Konstantin Batygin and Michael Brown, argue that an unseen planet several times larger than Earth could be "shepherding" smaller objects in the solar system. Batygin and ...

Ever since Pluto was demoted from planet status, astronomers believe a real Planet Nine exists in the solar system ...
