So close... You used sidereal days instead of solar days in all but one case, Venus. Although, precision could also be improved for Mars and Neptune. https://en.wikipedia.org/wiki/Rotation_period …

Oh my goodness. I will rerender with that correction. Good spot!

This exchange is a beauty to behold. Civilization is getting better with each conversation like this. Thank you!

It's true, this is how we do science!

if only politicians could do the same. impressive, great job. thank you.

This is superb. I had no idea Mercury and Venus had such tiny axial tilts. Just out of interest, by 1d do you mean 24h or do you mean 23h 56min?
-
1d is the SI unit 24hours. I'll put a legend in future figs. Cheers
-
There's no need to trouble yourself. I was just struck by how similar both quantities are for Earth and Mars. I can see the axial tilt differs by just a couple of degrees but I just wanted to check if the rotation period differs by 36 or 40 minutes. Nice work anyway.
-
Thanks! Yeah it came up a few times about the 1d thing. It's basically that 23h 56m is a sidereal day and 24hr is d (the solar day). Re: Venus, it is 177.3 or 2.7 deg tilt: the former is more properly called Obliquity to Orbit, the latter is Inclination of Equator (by NASA) 1/2
-
Axial tilt can be either, as best as I can see: it's simply the absolute angle between rotation axis and the orbit plane. Almost all of the time Venus is quoted as 177.3 deg in textbooks etc, but actually it looks like NASA are moving to say 2.7 these days. 2/2

Minor nit pick - Earth's axis is 23.45 degrees - but other than that - great graphic - I will retweet!
-
Thank you! Changing it to 23.4 (rounding down). (Rendering now, tis slow)
-
Oh, gosh, I didn't mean for you to redo it! Like I said, great graphic. I only know that value by heart because I do celestial navigation.
-
I love the fact that James was straight on it after your comment!
-
Haha, I was already doing a large correction for Venus (I used the Solar day, oops!). My key point in this was to be as precise as possible, since there's soooo many wrong versions out there.

Respect for trying to get it right!

Nice! What did you use?
-
Adobe After Effects, although I think there must be an easier tool out there
-
If you ever want a cheaper alternative to after effect check out Haiku -https://www.haiku.ai/
-
Cool thanks! Adobe is pricy, and many workarounds were needed on this animation

-
Yeah I hate the adobe pricing model so try and find decent alternatives where possible. The
@affinitybyserif suite (photo and designer) are pretty excellent photoshop and illustrator alternatives -
That's great! Thanks for linking. Now I just need something to replace Premier Pro...
