Key concepts

Charon

Charon is one of the most fascinating moons in our solar system, orbiting the dwarf planet Pluto. It was discovered in 1978 by James Christy and is considered the largest moon of Pluto. In fact, Charon is so large relative to Pluto that they are often referred to as a binary system. This is because the center of mass around which they both orbit is located between them, rather than within Pluto.

Charon's surface is mostly composed of water ice, with some evidence of ammonia hydrates and possibly methanol. The surface features include numerous chasms and rocks, indicating a past of geological activity. Scientists believe that billions of years ago, a massive impact on Pluto led to the formation of Charon. This event likely ejected a lot of material which later coalesced to form Charon as we know it today.

Thanks to missions such as NASA's New Horizons, we have gathered a lot of information about Charon's terrain and composition, giving us a better understanding of its characteristics and its relationship with Pluto.

Planetary Moons

Moons, also known as natural satellites, are fascinating celestial bodies that orbit planets or dwarf planets. They vary widely in size, composition, and origin stories. While some moons like Earth's own Moon formed in tandem with their host planet, others were captured by their planet's gravity.

There are over 200 known moons within our solar system, each with unique features and histories. Many of these moons differ in size, ranging from small asteroid-like bodies to massive moons like Ganymede of Jupiter or Titan of Saturn, whose atmospheres and potential for liquid water have intrigued scientists.

Planetary moons can influence their primary planets significantly. They can cause tidal forces, impact geological activity, and even contribute to the planet's weather patterns. Modern science strives to uncover the mysteries of these moons, as they can provide vital clues about the formation and evolution of the solar system.

Studying planetary moons is an essential part of understanding our cosmic neighborhood, as each moon has its own story, contributing to a larger narrative about the complexities and timelines of celestial formation.
