Moon Distance You may use the keys m, d, h to increase the month, day, or hour, or shift key and m, d, h to decrease the month, day, or hour. Click into the applet area first ! Click the applet area first. Then: enter decimal degree values for Latitude (southern negative) into the text field of the applet, and press Enter key, enter decimal degree values for Longitude (western negative) into the text field of the applet, and press Enter key. Latitude 51.51, Longitude 13.41 is Berlin/Germany. Latitude 40.76, Longitude -73.97 is New York. The applet is computing the distance of the Moon from the Earth (kilometers), the apparent angular size (arc minutes), and illuminated fraction of the disc of the Moon (per cent), and the Moon's phase: 0.00 = new Moon 0.25 = first quarter 0.50 = full Moon 0.75 = last quarter 1.00 = new Moon The altitude is taking into account the horizontal parallax of the Moon. Distance / km Perigee 356,375 Mean 384,401 Apogee 406,720 Select "Data" from the Details menu: Select "Diagram" from the Details menu: The change of distance may be up to about 6,300 km per day. The mean perigee distance of 284 anomalistic months is 362562.4 km.
