For reference, Pluto’s average distance from the Sun is about 40 AU, so 2023 KQ14 is quite distant. At 23.4 billion miles (37 ...

We've only known about its existence for a few short weeks, and already astronomers have been able to learn a lot about the mysterious interstellar comet 3I/ATLAS. The object was detected on 1 July ...

Astronomers are scrambling to gather data on a mysterious object that’s currently hurtling through the solar system.

When white dwarfs—the hot remnants of stars like our sun—are orbited closely by another star, they sometimes steal mass away ...

Alone among known planets, Earth has vast oceans on its surface and its landmasses are marked with lakes and extensive river drainage systems. Water is the biosphere's lifeblood, and without it, Earth ...

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 ...

One physicist is proposing we do away with units such as light-years, astronomical units, and arcseconds.

Now the diameter of the known universe can be described as 558 billion trillion miles (that’s 558 followed by 21 zeros) or 28 ...

Some of that seems to be related to a general lack of familiarity with what an astronomical unit actually is (it's the distance from Earth to the sun, for the record), but there's also the fact ...

Westmont will open its observatory and powerful Keck Telescope for this month’s free public stargazing event, beginning at 8:30 p.m. and lasting several ...

Using parallax during the transits of Venus, astronomers were given the best opportunity available to measure the distance from the Earth to the sun — known as one astronomical unit.

Earth's orbital distance from the sun is called an astronomical unit. 2017 OF201 is currently located at a distance of 90.5 astronomical units from the sun, meaning 90.5 times as far as Earth.
