Lunar Distance Calculator
Real-time Earth–Moon distance with perigee / apogee context.
Try the tool
Earth–Moon distance: 387710 km
In Earth radii: 60.86
Perigee ~356,500 km · Apogee ~406,700 km · Mean 384,400 km.
Tool principle
Approximates lunar distance as 385,000 km − 21,000 km · cos(anomaly), using the anomalistic month (27.55 days) referenced to a known perigee epoch.
Data source: Native orbital algorithm.
User guide
- 1Select any date to see the approximate Earth–Moon distance.
- 2Perigee (~356,500 km) produces 'supermoons'; apogee (~406,700 km) is a 'micromoon'.
