How Fast Is Moon's Orbital Speed?

The Moon orbits Earth at 1,022 m/s — about 3,680 km/h, completing one full orbit every 27.3 days. It is also drifting outward at 3.8 cm per year, gradually stealing rotational energy from Earth and making our day longer.

The Moon steals 3.8 cm of orbital radius from Earth every year — gradually lengthening our day in the process.
