Here is a fun animation that will help you to understand the relative rpms of the planets.

@futurebird
great idea.
but
that earth is missing Aotearoa / New Zealand ! Also no Japan, most of Indonesia missing ...
at first I thought it was just too much video compression, but Madagascar is there, so I'm not sure why so much other stuff is missing.
and I'm disappointed that Olympus Mons and Hellas basin are not identifiable on Mars. : (
Probably I'm too picky.
I use arch btw (pacman, not rpm)
(bad joke please do not hurt me)
@MichaelPorter
ooh and frantically waving arms for the faster ones.
@futurebird Oh this is cool!
Also, how did I never know that Pluto had such an extreme axial tilt?
@TopWKone @futurebird depends on how you determine the direction of rotation. It could be โbackwardsโ but the convention is that rotation is always counterclockwise when seen from โaboveโ (right hand rule) and so Venus is โupside downโ. (Hence the upside down smiley face)
Itโs also got a day thatโs 117 earth days long, so a Venusian year is just under 2 โdaysโ long.
@futurebird
Super cool!
You donโt hear much about rotation speeds.
I wonder about the sunโฆ?
@futurebird
1) Venus doesn't spin at all?!?
2) who let in Ceres? ๐
@futurebird I love this so much!
@gwynnion thanks for letting us know about it.
@ellenor2000 @futurebird If you count Pluto, you should count Ceres, too. And Eris, and a whole bunch of the other dwarf planets.
But that gets to a crowded illustration, and Pluto and Ceres are the ones with the best- imaged surfaces.

++ for including Pluto and Ceres
@latca @futurebird @futurebird the sun is a 'gas planet' and it's rotating pretty slow. or do we measure it relative to radius or mass or?
but lets think. if you form by being a rotating gas cloud that CONTRACTS then angular momentum says you speed up.
if you r a rocky planet and grow from agglomeration of random planetesimals... maybe you don't have that mechanism of speedup.
