"It is possible that a planet once existed in the solar system but was later ejected, causing the unusual orbits we see today." Astronomers have discovered a massive new solar system body located ...

NEW YORK (AP) — A new Tatooine-like planet outside the solar system may orbit two failed stars, scientists reported Wednesday. In a race back to the moon, US and China see a fast-approaching finish ...

“The object’s aphelion—the farthest point on the orbit from the sun—is more than 1,600 times that of Earth’s orbit,” Institute for Advanced Study’s Sihao Cheng mentioned in a recent press release. As ...

Scientists from UNSW Sydney have located a potential new exoplanet – a planet that orbits a star outside of our solar system – using a technique known as ‘transit timing variation’. In research ...

The asteroid belt orbiting between Mars and Jupiter would hurl fragments if it got destabilized, turning it into dust upon mutual collisions.

A new Tatooine-like planet outside the solar system may orbit two failed stars, scientists reported Wednesday. Located about 120 light years away, the exoplanet appears to take an unusual path around ...

There’s a new frozen oddball orbiting the Sun, and it’s not your average space rock. It’s a planet—a minor one, to be fair—but one of the largest yet discovered and with an orbit around the Sun that ...

Solar power has become an important part of our civilization, especially in recent years, and it is presently crucial to our existence. Solar panel farms spread far and wide across the planet, on ...

A possible cousin of Pluto seems to be circling the far reaches of the solar system. The dwarf planet candidate 2017 OF201 travels in a superwide orbit, with the sun relatively near one end of its ...
