Moon Distance Explorer
Slide the Moon from 60,000 km to 800,000 km away.
- Orbital period (Kepler)
- 27.4523 days
- Apparent size in sky
- 0.517808°
- Light travel time
- 1.28222 s
Assumptions: circular orbit around Earth, Moon diameter 3,474 km. Tides scale roughly as 1/distance³, so half the distance ≈ 8× the tidal force.
Model assumptions
Circular orbit, Kepler's third law around Earth, Moon diameter 3,474 km.
