Reply to comment by stayalive2020 in How much has our view of the Moon changed throughout human history? When I look up am I seeing the Moon as it appeared, more or less, to William the Conquerer? Caesar? King Tut? by ayebrade69
You wouldn't notice it over the span of the entire human history. Even per 10000 years, that's less than half a kilometer. The moon's orbit varies by 40 thousand kilometers between perigee and apogee every two weeks.
You might start noticing movement if you make frames of a million year's change, and even then after a minute of that video (so about the dinosaur extinction) it would have shifted by a few thousand kilometers, less than the perigee-apogee difference.

No worries, it's just funny when you learn that "oh, it's moving away almost 4 centimetres a year, that's a clearly measurable distance. Mountains grow that fast" but then realise you're talking about literal astronomical distances, lol
