moon wobble in video :)


Recommended Posts

a friend just pointed out this link to me:

Video: Year of Moon Motion in 2.5 Minutes | Wired Science | Wired.com

from the article:

"Many claim to see a man in the moon, but now an animation has been made that showcases a year’s worth of moon movements in less than three minutes."

thought it might interest everyone else around here too. :)

(Another reason why "stupid" questions are'nt. They sometimes force us to correct our misconceptions).

There are actually three kinds of librations (wobbles) that affect the Moon. Here all explained in excruciating detail:


Take care
