more than half the size of Pluto itself (Figure 2). This makes Charon the moon whose size is the largest fraction of its parent planet. We could even think of Pluto and Charon as a double world.
Pluto has one large moon, Charon. Indeed, Charon is more than half of Pluto's diameter, though much less massive, and both Pluto and Charon orbit a common center of mass which is above Pluto's surface (making this a binary system of two primary bodies, of which one is a planet and ...
Pluto is not visible in the night sky to the unaided eye. Its largestmoon,Charon, is close enough in size to Pluto that it has become common to refer to the two bodies as a double system. Pluto isdesignatedby the symbol ♇.
Pluto has five known moons: Charon, Nix, Hydra, Kerberos, and Styx. The largest of these, Charon, is half the size of Pluto itself and remains tidally locked to Pluto at all times. This means that the same sides of Pluto and Charon are always facing each other, which, combined with C...

Pluto, Charon, and USA Comparison This image shows the approximate size of Pluto and Charon by overlaying them on an Advanced Very High Resolution Radiometer (AVHRR) image of the United States of America. Pluto is about 2274 kilometers (1410 miles) in diameter and Charon 1172 kilometers (72...
Astronomers weren’t sure about Pluto’s mass until the discovery of its largest Moon, Charon, in 1978. And by knowing its mass (0.0021 Earths), they could more accurately gauge its size. The most accurate measurement currently gives the size of Pluto at 2,400 km (1,500 miles) across....
"pluto and charon are going to steal the day today, but let's not forget that pluto has four small moons as well that we want to collect data on," says new horizons project scientist hal weaver. "this morning, we got the first really well-resolved images of hydra." science newsletter...
The Pluto–Charon system has complex photometric variations on all time scales; due to rotational modulations of dark markings across the surface, the changing orientation of the system as viewed from Earth, occultations and eclipses between Pluto and Charon, as well as the sublimation and condensat...
Partial differentiation has even been suggested for bodies as large as Charon29,30,31,32. The implications of this discrepancy are considered in the ʻDiscussionʼ. In any case, the smaller size of the impactors implies that there is a cooler temperature than that of Pluto, and they are,...
