Moon
The Moon is Earth's natural satellite and one of the easiest sky objects for people to connect with when learning how orbits work.

The story
The closest major world beyond Earth
The Moon is the nearest large natural object to Earth and has shaped human understanding of the sky for thousands of years.
In the TransitSatellite Solar System map, the Moon helps users understand that not everything in space orbits the Sun directly in the same way. Some objects, like moons and artificial satellites, orbit planets.
Orbit explained
A moon is an orbiting world
The Moon follows a path around Earth while the Earth-Moon system travels around the Sun. This layered motion is a useful way to explain how orbits can exist inside larger orbits.
That same idea helps users understand artificial satellites. A spacecraft can orbit Earth while Earth itself continues moving through the Solar System.
Why it matters
The Moon makes orbital motion easier to understand
Because the Moon is familiar and visible, it can help students and skywatchers understand more complex orbital ideas before moving on to satellites, planets, and deep-space missions.

Missions connected to this world
These linked mission pages explain how spacecraft have studied moon: their objectives, paths, instruments, and results. Each page carries its own mission record rather than repeating the planet description.
Why this belongs in the Library
The Moon belongs in the Library because it helps explain layered motion: a moon can orbit a planet while both move around the Sun.
