The animations are a bit confusing right now. According to the labels, it's showing the Sun orbiting the Earth? I'm assuming the labels are wrong or it's from some weird frame of reference? Also, the one on the left seems to show PT5 landing on the Earth for a few months before taking back off and leaving. It could bear explaining what's really happening there. - Qwerty0 (talk) 20:15, 24 September 2024 (UTC)Reply

@Phoenix7777 @Qwerty0, this also stunned me. I'm in no way an expert but the left animation seems to be a little faulty. Kiwiz1338 (talk) 13:16, 30 September 2024 (UTC)Reply
I have also tried to wrap my head around these animations. I think, on the left, every object is shown from the perspective of a fixed earth, so everything rotates around it. And the asteroid doesn't actually land on the earth but at the scale of 1AU, it is so close to the earth that it appears at the same place. The objects are also not to scale, otherwise the earth would be at most 1 pixel, and the asteroid would be invisible. What's the little confusing is that on the left, every object rotates in the same direction, but on the right the moon and the asteroid orbit in opposite direction. But that's an artifact of adding or not adding the rotation of the earth. So, the animation on the left may actually be correct from the perspective of a fixed earth, but that's a weird perspective.

Agreed, Phoenix has started a disscisson on their talk page. See User_talk:Phoenix7777#Earth's_rotation_in_orbit_animations. Kiwiz1338 (talk) 12:03, 4 October 2024 (UTC)Reply
