Moon - A natural satellite that orbits a planet, Asteroid - A small rocky body orbiting the Sun, left over from the early solar system; these can travel too close to a planet then become a moon by capture, Accretion - The gradual build-up of larger bodies (planetesimals, protoplanets, or moons) through the collision and sticking together of smaller particles., Barycentre - The centre of mass around which two objects (such as a planet and its moon) orbit; the barycentre must be within the planet for something to be classified as a moon, Circumplanetary Disk - A disk of gas, dust, and debris surrounding a young planet, from which moons can form., Prograde Orbit - An orbit in the same direction as the planet’s rotation (most large moons, like our Moon, orbit this way)., Retrograde Orbit - An orbit opposite to the planet’s rotation, often evidence that a moon was captured rather than formed in place., Elliptical Orbit - An oval-shaped orbit with varying distance between the moon and the planet it orbits., Collision Moon - A moon formed from debris after a large impact between a planet and another body eg. The Moon, Accretion Moon - A moon formed directly from material in a circumplanetary disk around a young planet eg. the Galilean moons of Jupiter, Captured Moon - A moon that was once an independent body (like an asteroid) but was later pulled into orbit around a planet due to gravitational capture.,
