From Pluto’s tilted orbit to rogue asteroids, discover the chaotic leftovers of solar system formation. This video explains NASA’s DART mission, why some planetary orbits defy predictability, and ...

Scientists have been trying to find a hypothetical Planet 9 that may exist outside our known solar system based on the unusual orbits of certain dwarf planets. But those orbits might not require a ...

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 ...

The orbits of the planets around the Sun have been the source for many a scientific debate. Their current orbital properties are well understood but the planetary orbits have evolved and changed since ...

ESA's Gaia mission has determined he orbits of 154,741 asteroids in our solar system. Credit: ESA/Gaia/DPAC ...

Gravity not only maintains the stability of these orbits but also influences phenomena like tides on Earth, caused by the moon's gravitational pull. The paper, authored by David Jewitt from the ...
