Why is Charon so big?
With half the diameter and one eighth the mass of Pluto, Charon is a very large moon in comparison to its parent body. Its gravitational influence is such that the barycenter of the Plutonian system lies outside Pluto….Charon (moon)

What would happen if Charon and Pluto collide?
In the aftermath of the huge Charon-forming collision, then, multiple generations of smaller satellites were likely created and destroyed, their pieces moving outward and coming together once again to form new moons of Pluto.
How far apart are Pluto and Charon?
Charon is almost half the size of Pluto. The little moon is so big that Pluto and Charon are sometimes referred to as a double dwarf planet system. The distance between them is 19,640 km (12,200 miles). The Hubble Space Telescope photographed Pluto and Charon in 1994 when Pluto was about 30 AU from Earth.
Does Pluto orbit Charon?
153 hours
Charon/Orbital period
How big is Charon vs Earth?
Recent measurements obtained by New Horizons indicate that Pluto has a diameter 18.5\% that of Earth’s, while Charon has a diameter 9.5\% that of Earth’s.
Will Pluto eventually collide with Charon?
The twin worlds are relatively similar in size (Earth’s Moon is 1/80 our planet’s mass, while Charon is roughly 1/10 Pluto’s), but have dramatically different densities, making it unlikely they could have formed together simultaneously in the solar nebula.
How did Pluto and Charon form?
One theory suggests that Charon was created when a neighbouring Kuiper Belt object collided with Pluto. That destroyed the impactor, sending chunks of debris into orbit around Pluto. Another idea suggests that infant Pluto and Charon collided, but did not break apart. Instead they went into orbit around each other.
How close is Charon to Pluto’s Roche limit?
How close is Charon to Pluto’s Roche limit? The distance between them is 19,640 kilometers (12,200 miles). The Hubble Space Telescope photographed Pluto and Charon in 1994 when Pluto was about 30 AU from Earth.
How long does it take Charon to orbit Pluto?
How big is Pluto’s moon Charon?

Why do Charon and Pluto always face each other?
The same surfaces of Charon and Pluto always face each other, a phenomenon called mutual tidal locking. Charon orbits Pluto every 6.4 Earth days. Charon is almost half the size of Pluto. The little moon is so big that Pluto and Charon are sometimes referred to as a double dwarf planet system.
Charon’s orbit around Pluto takes 6.4 Earth days, and one Pluto rotation (a Pluto day) takes 6.4 Earth days. Charon neither rises nor sets, but hovers over the same spot on Pluto’s surface, and the same side of Charon always faces Pluto―this is called tidal locking. Compared with most of the planets and moons,…
What is the size of Charon?
Charon is about half the size of Pluto with about ⅛ the mass. The barycentre (centre of gravity for the system) is about 2,000 kilometres from the centre of Pluto and 17,000 kilometres from the centre of Charon.
Does Charon ever rise or set?
Charon neither rises nor sets, but hovers over the same spot on Pluto’s surface, and the same side of Charon always faces Pluto―this is called tidal locking. Compared with most of the planets and moons, the Pluto-Charon system is tipped on its side, like Uranus.
