Due to it’s slow rotation it actually completes a full rotation of the sun before it itself fully rotates.

I love how much of a rebel non-conformist Venus is. Years longer than its days, rotates the opposite direction than all other planets because fuck you, thats why. And don’t you even THINK about getting close and trying to land on her. Just ask the Russians how that went. You can’t handle her pressure, temperature nor toxic atmosphere. What a bad bitch. She doesn’t need nor ask your permission to do jack shit.
Yeah she’s hot and toxic, but I can change her…
Bro talking about terraforming venus while we’re still not done venusforming earth.
rotates the opposite direction
By this, you mean its rotation around its own axis?
Venus sure as shit wont rotate around anyone else’s axis. Venus dgaf.
😂 joking aside, was referring to its solar orbit 😁
Yeah, most planets have the same rotation direction as orbital direction (counter-clockwise rotation, counter-clockwise orbit) but Venus rotates clockwise.
It kinda depends how you define “a day”. The usual standard colloquial definition we use would be a “solar day”, i.e. how long it takes for it to go dark and light once each, i.e. noon to noon.
The definition you’re using in this post though is a “sidereal day”, which if you just say “a day” no one would mean, thus this post is misleading. A sidereal day is how long a planet needs to spin around itself.
A Venus “solar (normal) day” (like we normally use the phrase “day”) is 116.75 earth days, while a Venus year is 224.7 earth days. The “sidereal day” that you’re talking about here is 243 earth days long. So a day on Venus is actually shorter than a year on Venus, at least if you use our usual definition of “day”.
Since Venus itself spins opposite to its orbit around the sun, its own spin together with its orbiting around the sun add up together to make the “solar (normal) day” shorter.
An Earth sidereal day is 23 hours 56 minutes while its solar day is 24 hours long. Here, the sidereal day is shorter than the solar day, because the Earth spins in the same direction as its orbit.
Thanks, I came looking for this clarification.
LLMs love giving the sidereal day as the length for some reason.
Hey OP! I’d rather spend a day with you than on Venus!
One is rotation, but the other is revolution.
Rotation: circular motion of a body about its own axis.
Revolution: motion of an object moving around another object.
This one fact always blows my mind.
I think my physics teacher told me this fact but followed it up with “Measuring a planet’s rotation around the sun by how fast it rotates around it’s center is like trying to measure the speed of a truck based on how many rotations a ballerina can spin inside of it.”
That quote haunts me.
Bit silly. In this scenario, you’re not measuring the speed of the truck. You’re measuring the time it takes to complete a lap. And we are the ballerina rotating, and as we are a miniature plastic ballerina with no outside frame of reference, our own regular rotation is the only consistent measure we have.
How did the ballerina get inside the truck? Is she alright?!
Is she spinning because she’s happy? Or is she spinning to drill a hole in the floor and escape?
Are we talking sidereal day or solar day? Both?
quality TIL post. we didn’t know this either!
It took me like three readings of the post title to comprehend it wasn’t a typo lol
