Researchers just got a step closer to understanding the origins of our solar system, with the discovery of an object orbiting the sun—dubbed "Ammonite." The findings were recently published in the ...

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

Subaru Telescope has made an exciting discovery: a small body beyond Pluto, with implications for the formation, evolution, ...

"Makes your ship's HUD display interstellar distances in light years (LY) instead of astronomical units (AU). Also increases the maximum light second (LS) value from 50,000 to 500,000.

They have since confirmed it is the most distant object yet found in our solar system. The team has since learned that Farfarout resides 132 astronomical units (AUs) from the Sun.

The orbit of Ammonite (red line) and the orbits of the other three sednoids (white lines). Ammonite was discovered close to its perihelion, at a distance of 71 astronomical units (71 times the average ...

A graphical representation of our solar system to scale - see how far the planets are from the sun in astronomical units.

Without fanfare, astronomers have redefined one of the most important distances in the Solar System. The astronomical unit (au) — the rough distance from the Earth to the Sun — has been ...

The International Astronomical Union, based in Paris, decided in 1976 to define the astronomical unit of time as one day of 86,400 seconds.

The scale indicates a distance of 4,000 astronomical units (AU), where 1 AU is the average distance between the Earth and the sun (about 93 million miles, or 150 million kilometers).
