Perigee and apogee

Event	Date and time (UTC)	Distance
Apogee	1 August 2025 at 20:37	404,150 km
Perigee	14 August 2025 at 17:58	369,277 km
Apogee	29 August 2025 at 15:33	404,537 km

The Moon's distance varies by more than 40,000 km over a month. At perigee the disc appears about 14% wider than at apogee — a difference that is obvious in a photograph and almost impossible to judge by eye, since there is nothing in the sky to compare it to.
