The Solar System is a fascinating place, with each planet orbiting the Sun at its own unique distance. But how far apart are these planets, and how do they travel through space? Uncover the true scale ...

It’s currently 132 astronomical units (au) from the Sun—1 au being the distance between the Earth and Sun, which is the unit of measurement used by astronomers to describe the Solar System.

Astronomers have discovered a "fossil" world lying in the outskirts of the solar system, according to new research.

An artist's illustration imagines the newly discovered Farfarout (lower right), now confirmed to be the most distant object ever observed in our solar system. Farfarout is 132 times the distance ...

The distance of the Oort Cloud to the interior of the Solar System. The scale bar is in astronomical units, with each set distance beyond 1 AU representing 10 times the previous distance.

For example, Atkin proposes that megameters (Mm, 10 6 m), gigameters (Gm, 10 9 m), and terameters (Tm, 10 12 m) be used for planetary- and solar system-scale distances, making Earth’s radius 6. ...

Xena is currently about 97 astronomical units from the sun (an astronomical unit is the distance between the sun and Earth), which means that it is some nine billion miles away at present.

Astronomers now know when the solar system’s molecular cloud began to collapse, it measured 100 astronomical units across (1 astronomical unit is the average distance between the Sun and Earth ...
