Dec. 19, 2024 — New studies offer a clearer picture of how the outer solar system formed and evolved based on analyses of trans-Neptunian objects (TNOs) and centaurs. The findings reveal the ...

Samples of Bennu were brought back to Earth by NASA’s OSIRIS-REx spacecraft in 2023. Now, a pair of newly published papers ...

There are also many in a region beyond Neptune called the Kuiper Belt. The solar system also contains small objects called comets. Comets are similar to asteroids, but are made of ice, dust and ...

But our own Solar System's disc is relatively warped, with the orbits of its planets slightly tilted and more oval than circular. What happened to it? It's possible a heavy object fell into the mix ...

Conduct more detailed simulations to refine the characteristics of the interstellar object and its encounter with the solar system. Search for observational evidence of such past encounters in the ...

Every object in our Solar System is held in place by the Sun’s ... to Earth having liquid water on the surface, which living things need to survive. Evidence from the Curiosity and Perseverence ...

“Surprisingly, many of these so-called trans-Neptunian objects move on eccentric orbits that are inclined relative to the ...

A massive interstellar object passing through our solar system during its formative years likely altered the orbits of planets into trajectories observed today, a new study says. Interactions with ...

An interstellar visitor may have warped the solar system billions of years ago, a new study has claimed. Scientists suggested the enormous object disrupted the orbits of Jupiter, Saturn ...

A new study suggests that a planet-sized object may have passed through the solar system billions of years ago. Its journey could have permanently altered the orbits of the outer planets.

NASA artist’s conception of a brown dwarf (main) and stock image of the planets in the solar system (inset). An object between 2 and 50 times the mass of Jupiter may have flown through our ...

front of Jupiter's Great Red Spot. Mars is a famously red object in our solar system, but it’s not the reddest. That honor goes to Amalthea, a tiny moon orbiting around massive gas giant planet ...
