Yes, not only does the apparent size of the Moon change, but so does the centre of its disc.

Lunar Libration 2006
An extremely cool video animation of lunar libration throughout 2006. This shows not only how the Moon comes closer and recedes in its orbit, but also the "wobble" or Libation it has.

Anonymous commenters - please add a signature (doesn't have to be your real name) on each post of yours. Anne O'Namus, Norm D. Ploom, Angry from Kent, Demosthenes, or even your real initials, it doesn't matter.
Commenters are expected to be polite to each other, but the same standard doesn't apply to comments regarding me.
Australian commenters are very very strongly advised to publish anonymously. Sydney alone has more defamation actions than the entire USA and UK. Nearly double that of the UK in fact.
As Google does not reliably inform me that a comment has been posted, and I have no control over first publication, I assert that all comments are innocently disseminated under the NSW DEFAMATION ACT 2005 - SECT 32 and similar acts.
I wondered at the title whether this might be something menstrual; but in fact it's libration.
ReplyDeleteOops. Corrected :)
ReplyDeleteAwesome. My favourite heavenly body put on a good show last year.eh? Last night's moonrise over Blighty was spectacular too - huge, full, glowing amber.
