Feb. 18 marks the 95th anniversary of the discovery of our outermost planet-not-planet. Here's what to know about the short ...

Even when they finally separated, they were forever linked with Charon hovering around Pluto in orbit to this very day. “Most planetary collision scenarios are classified as ‘hit and run’ or ...

On the 95th anniversary of its discovery, Pluto remains one of the most beloved and enigmatic worlds in our solar system, ...

According to a recent YouGov poll, 35% of Americans think Pluto is not a planet. But they are all wrong—kind of. To get to ...

Most moons orbit their planets, but Pluto and Charon are different—they revolve around a point in space between them! 🔄 Why does this happen, and what did NASA’s New Horizons mission reveal ...

6 - The mass of Charon is so large — and the mass of Pluto is so small — that Charon doesn’t actually orbit the dwarf planet. Instead, both orbit a fixed place in space between them.

The researchers also simulated the collision of Orcus and Vanth, another pair of co-orbiting icy objects out beyond Neptune’s orbit with a mass ratio similar to that of Pluto and Charon.

Even when they finally separated, they were forever linked with Charon hovering around Pluto in orbit to this very day. “Most planetary collision scenarios are classified as ‘hit and run’ or ‘graze ...

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. Astronomers zoomed in on a stellar behemoth in the ...
