"In modern dynamical models, the giant planets are thought to have migrated over substantial distances, shaking up the asteroids — which formed throughout the solar system — like flakes in a ...

Driving this view was the effect on the main asteroid belt of planetary migration models that aimed to recreate the structure of the rest of the Solar System, such as the orbits of the giant ...

The main asteroid belt, located between the orbits of Mars and Jupiter, makes up 0.05 percent the mass of Earth. The asteroids there can range greatly in mass, with the four largest ones — Ceres ...

Understanding the history of water distribution in the solar system will help us to understand other planetary systems, and if they could be on their way to hosting an Earth-like planet,” said ...

Indeed, our own solar system's asteroid belt is considered to be a "failed planet" of sorts; there are multiple small spherical bodies that make up the asteroid belt, including Ceres, Vesta, and ...

Rocky bodies called protoplanets were thought to have formed slightly earlier in the inner solar system than those beyond the ...

The first asteroid belt ever seen outside the solar system is more complex than expected, astronomers found, using observations by the James Webb Space Telescope. Looking at the warm dust around a ...

I/ATLAS, earlier known as A11pI3Z, is only the third interstellar visitor to be discovered passing through our corner of the ...

An entire asteroid doesn't just materialize out of nothing, though, and now astronomers have determined what 2024 YR4 is made of, what it looks like, and the unexpected place in the Solar System ...

There are five known dwarf planets in our solar system. One of them is named Ceres, after the ... It has a diameter of over 620 miles and is located in the asteroid belt. For a long time, it has ...

However, that’s not even the most interesting feature of the Fomalhaut system. Outside of Fomalhaut’s inner asteroid belt, there is a second debris belt that is tilted at 23 degrees from ...

A better understanding of the asteroid belt has revealed just how dynamic the solar system was in its early days, a new study reports. "In modern dynamical models, the giant planets are thought to ...
