For me it is the fact that our blood contains iron. I earlier used to believe the word stood for some ‘organic element’ since I couldn’t accept we had metal flowing through our supposed carbon-based bodies, till I realized that is where the taste and smell of blood comes from.
A day on Venus is longer than a year on Venus. One day takes 243 Earth days, while a year takes 225.
Maybe it’s not “well known”, but still interesting in my opinion.
I mentioned this one to my friends the other day and it took so much convincing before they actually believed me! Definitely an interesting one. Venus also spins the opposite direction to all the other planets in the solar system, meaning the sun rises in the west and sets in the east.
Wouldn’t spinning in the opposite direction indicate that it’s axial tilt is flipped or something?
The leading theory is a moon sized object hit it with enough force to spin it backwards.
The energy used to reverse the existing motion might explain why it’s so slow
I’ve seen this fact somewhere before, but I still am unable to grasp it in my mind
How does this affect its gravity?
It doesn’t. Gravity is related to its mass, not it’s orbit or rotational velocity.
The others already said the core aspect, but to get specific: the difference between your weight on the pole and your weight on the equator differs only by like .5% or something like that. This is the difference between spinning and not spinning (centrifugal force and no centrifugal force). (And also the difference in radius, since the Earth’s rotation makes it a tiny bit flatter than a perfect sphere would be)
