Astronomy Picture of the Day - Planets of the Solar System: Tilts and Spins
APOD.NASA.gov ^ | 11 Sep, 2022 | Video Credit: NASA, Animation: James O'Donoghue (JAXA)

Explanation: How does your favorite planet spin? Does it spin rapidly around a nearly vertical axis, or horizontally, or backwards? The featured video animates NASA images of all eight planets in our Solar System to show them spinning side-by-side for an easy comparison. In the time-lapse video, a day on Earth -- one Earth rotation -- takes just a few seconds. Jupiter rotates the fastest, while Venus spins not only the slowest (can you see it?), but backwards. The inner rocky planets across the top underwent dramatic spin-altering collisions during the early days of the Solar System. Why planets spin and tilt as they do remains a topic of research with much insight gained from modern computer modeling and the recent discovery and analysis of hundreds of exoplanets: planets orbiting other stars.

Maybe this is where the UFOs come from the Navy is making a big deal out of. What a BS joke.

Planets?

I shot this image of Jupiter on the 3rd of this month, but conditions were not good. But we've had so much rain in my area of Arizona I was anxious to try some new settings and had a small window of opportunity.

This was from 27,000 frames of video which I processed resulting in the best 500 frames which were combined into this image. I do not have a dedicated planetary camera so I used a consumer grade Canon DLSR.

Nice video!
It’s pretty cool to see them side by side like that.

Very nice! I can only imagine how much nicer it would be if the seeing were better.

Much better. Where I am in AZ, this summer it seemed every cloud that came over it rained. We need the rain but not daily like Hawaii. Not complaining, it is what it is. So green you’d never know this is the high desert.

Wow, Uranus really has a radical tilt!

How did that happen; did something collide with it in the distant past?
