The action is unfolding in a location comparable to the asteroid belt between Mars and Jupiter containing the leftover building blocks of our solar system’s planets.

Prevailing solar system formation theories indicate that these planets should have at least started out following perfectly circular and share the same orbit.

HOPS-315 is also giving astronomers a new opportunity to study early planet formation, serving as a stand-in for newborn solar systems across the galaxy.

Ultimately, without a time machine, we will never fully recover the precise history of our solar system's formation, so we will never be entirely sure what role giant impacts had in the ...

Arrokoth is a planetesimal in the Kuiper Belt, a vast stretch of space beyond Neptune that holds remnant building blocks of the solar system leftover from our cosmic neighborhood's formation.
