Our asteroid belt is home to more than a million space rocks, varying in size from a dwarf planet to dust particles, which float between Jupiter and Mars. Astronomers have just discovered another ...

There appears to be a gap between 55 AU and 70 AU where no objects have yet been found, and then a second belt — let's call it "Kuiper Belt 2" — between 70 and 90 AU, which is as far out as 13 ...

There may be a new population of Kuiper Belt objects at 70-90 au. “If this is confirmed, it would be a major discovery. The primordial solar nebula was much larger than previously thought, and this ...

Our solar system is a pretty wild place, full of amazing stuff. From the giant Sun to the tiny rocks floating around, there’s ...

There are five known dwarf planets in our solar system. One of them is named Ceres, after the Roman goddess of corn, agriculture, and harvests. Ceres is the closest dwarf planet to the sun. It has ...

The Kuiper Belt lies about 40 to 50 astronomical units — that's 40 to 50 times the average distance between our planet and the Sun — from the center of our system.

Researchers have used the Subaru Telescope in Hawaii to peer out to edge of the Solar System known as the Kuiper Belt to discover any objects. 11 objects were discovered, and they appear to be ...

The 23-degree tilt of the Earth’s axis would have caused the ring to present its surface to the sun, casting a shadow in the atmosphere and on the ground below and causing global temperatures to ...

A computer simulation shows how a large-enough asteroid could have been captured by Mars and torn to shreds by the planet’s gravity, briefly forming a debris cloud — and possibly a ring system ...

As the solar system formed, many C-type asteroids came to inhabit the outskirts of the main asteroid belt, a ring containing millions of rocky objects between Mars and Jupiter.It's here the six ...

If Earth captured a passing asteroid around 466 million years ago, it could have ripped it to shreds and formed a ring. This debris would then rain down on the planet, focused on the equator, over ...
