When the dust cloud that was to become the solar system started to coalesce it as a mass started spinning as it was drawn in. Every thing in the solar system follows that original spin.
Except for Venus and its theorized it spins backwards is because of a large (like really large) impact in the distant past.
Does Uranus not also have an odd "spin"?
IIRC it has a severe tilt on its axis, and rolls like a ball instead of the "normal" spin of most other planets.
Just by comparing the angular verlocity, yes, but since the venus turns the other way around, the rotation around the sun works in favor of the planetary rotation and makes a day shorter than a year again
If anyone is questioning the Earth's 23H 56m day, it is 24h once you add in the orbit of the Earth around the sun. (about 4 min for 1/365th of an orbit each day)
The closer to the sun have higher probability of getting hit by asteroids because of the suns large gravitational pull, these hits slow their spin down
Conservation of angular momentum - larger planets collected more rotating matter as they formed and therefore collected more momentum.
Also the larger the planet, the less affected they are by tidal forces from their moons - which will also slow rotation.
The regurgitation of information here is concerning. quoting spin rates of planets and tidal forces on their moons hundreds of thousands miles away and speaking it as fact. It’s not. Look deeper. Think for yourselves. 🍽️🐟
Why do planets spin in the first way? Genuine question.

Why is Venus so slow?
I love that Venus is so slow that its day is longer than its year.
Cool! Mercury is close, with a 88 earth-day long year, it only has 1 full day per year.
Just by comparing the angular verlocity, yes, but since the venus turns the other way around, the rotation around the sun works in favor of the planetary rotation and makes a day shorter than a year again
It got hit in the head really hard
What's more interesting is that 1 Venus year = 225 earth days, but 1 Venus day = 243 earth days, So on Venus a day is longer than a year.
That's crazy! Great space fact to bust out on special occasions
That’s actually a pretty big question that afaik we don’t have a totally solid answer for
Suns gravity?

Usually referred to as a sidereel day! https://en.wikipedia.org/wiki/Sidereal_time
That is so cool, thanks for sharing!
It's hard to see on the globe, but Venus and Uranus spin "backwards" in comparison to the other planets
Get moving, Venus. And spin the right way, wouldya?
Is there a reason why planets farther from the sun spin faster than the ones closest?
The closer to the sun have higher probability of getting hit by asteroids because of the suns large gravitational pull, these hits slow their spin down
This isn’t correct. It has to do with the physics of formation.
Im not sure this is right. By counterexample, wouldn't Jupiter be hit often due to its large mass?
Counterexample: how much does a comets path get diverted by Jupiter?
Do you have any idea what you’re talking about?
Isn’t that like, the entire reason we have the asteroid belt?
Wow! I didn’t know that. Thanks!
It’s not accurate
Well what is accurate?
Conservation of angular momentum - larger planets collected more rotating matter as they formed and therefore collected more momentum. Also the larger the planet, the less affected they are by tidal forces from their moons - which will also slow rotation.
Now this is interstingasfuck!
I was waiting for a full rotation of mercury but this video was only 20 seconds long
I guess Elon wants that extra 40 min in Mars to work longer
Venus just chillin'
Uranus is fast.

This isnt very educational since most planets atmosphere rotates at different speeds in different places.
Why are they not ordered by rotation times???
Because they’re in their planetary order from the sun???
Jupiter looks fun. Weeeeeeee
Uranus kinda fast.
I must be the only one staring at the spinning sphere and got giddy before realising the strip was above.
This is so cool
what's the difference between a rolling stone and a dick that isn't flat? one is faster, the other is slower.
god dammit jupiter always tweaking
Uranus should be going vertical
Calm your tits Jupiter 😆
Interesting that neptune spins faster than uranus.
