The researchers created a computer model to predict the ways the planets would scatter, finding that slight tweaks to starting positions lead to vastly different outcomes
Our solar system is filled with planets, asteroids, comets, the sun and more, making it a wealth of discoveries waiting to be found. See the latest discoveries from across our solar system here.
Scientists used solar wind to make the first 3D map of the heliosphere, which protects Earth from deadly cosmic radiation.
Boulders on asteroids can be three-quarters hollow or more, a discovery that could help yield insights on the way in which Earth and other planets formed, a new study finds.
Metal atoms have surprisingly been discovered in the frigid atmosphere of the first known interstellar comet to visit our solar system, a new study finds.
Voyager 1 continues to make discoveries, most recently catching the signature of interstellar space itself, a faint plasma "hum" scientists compared to gentle rain.
These violent openings are windows into the inner workings and origins of our neighboring planets and their moons.
The mysterious heating of the sun’s corona might be powered by miniature solar flares dubbed 'campfires,' discovered by the European-US Solar Orbiter mission last year, a new study suggests.
For a few brief minutes, a suborbital rocket from NASA has an ambitious plan to seek out particles from interstellar space.
New Horizons is about to reach some very rarefied space, but don't expect the NASA probe to rest on its considerable laurels.
Astronomers have searched the entire Milky Way to identify the safest places to live. It turns out, we're in a pretty good spot.
The first known interstellar comet to visit our solar system may be the most pristine ever found, never passing near a star until visiting our own, researchers say.
'Oumuamua, the first known visitor from interstellar space, was likely a pancake-shaped chip off a Pluto-like world.
Does the solar system really have a big, dark ninth planet drifting somewhere far beyond the orbit of Neptune? A new paper argues that Planet 9 is a statistical mirage.
China has released epic video footage from the Tianwen-1 spacecraft as it made a close approach to Mars this week.
Astronomers have now collected enough additional data to confirm the existence of Farfarout and nail down its orbit.
Mars' Valles Marineris is nearly 10 times as long as the Grand Canyon and three times as deep, but nobody knows how it formed.
There's a giant asteroid somewhere out there in the solar system, and it hurled a big rock at Earth that left behind meteorites unlike any scientists had ever seen.
