Unlike how scientists believe Earth's moon formed billions of years ago, Pluto and its biggest moon, Charon, didn't have a ...

Charon is large in size relative to Pluto, and is locked in a tight orbit with the dwarf planet. A new simulation suggests how it ended up there.

Billions of years ago, in the icy outskirts of the solar system, a dramatic collision forged the unusual pairing of Pluto and ...

But these theories didn’t account for the fact that Pluto and Charon may have more structural integrity as icy, rocky bodies on the frigid edge of the solar system. “Pluto and Charon are ...

After passing Pluto, the craft will continue into the farthest reaches of the solar system. Scientists suspect there may be yet more moons around Pluto, some perhaps sharing or swapping orbits and ...

“Because Pluto is rotating rapidly prior to the collision, and because Charon lies mostly outside of their corotation zone, ...

This "kiss and capture" mechanism offers a fresh perspective on planetary formation, particularly about Pluto and its largest ...

Both systems include a moon that is a large fraction of the size of the main body, unlike other moons in the solar system. The scenario also could support Pluto's active geology and possible ...

Learn about the size, temperature, and colour of each planet, and discover why Pluto is no longer considered a planet.

NASA has given a new lease of life to its New Horizons mission, which in 2015 got the first-ever close-ups images of dwarf planet Pluto ... of the sun and its solar wind at the very edges of ...
