My fact and quite related: Venus is the only planet in our system to be "retrograde", meaning that it spins in the opposite direction

I could be wrong on that though...

Of course we don't really know that much about Venus since the atmosphere makes ground probes a bit hard.
I think I misread that when I looked it up ages ago, because it doesn't say anywhere that it was actually reversed, just that it was different. Ah well.Wikipedia said:When it formed from the solar nebula, Venus may have begun with a different rotation period and obliquity, then migrated to the current state because of chaotic spin changes caused by planetary perturbations and tidal effects on its dense atmosphere. This change in the rotation period probably took place over the course of billions of years
Erm, so how do you move your fingers then? I know I have flexors and extensors for that...Prof.Wood said:Human fingers do not contain any muscles other than the small muscles attached to each hair follicle which contract to make the hairs stand on end causing goose bumps.
It's not like this is a must-know or something anyway. Interesting, sure.

The first two are wrong.MrPatience said:A day on Venus is shorter than a day on Earth, but a year on Earth is shorter than a year on Venus.

The muscles are in your forearm. The fingers are controlled by those tendons you can see on the back of your hand. Also this is why it is very difficult to move your 4th and 5th fingers independantly, because they share the same muscles.Quaxar said:Erm, so how do you move your fingers then? I know I have flexors and extensors for that...Prof.Wood said:Human fingers do not contain any muscles other than the small muscles attached to each hair follicle which contract to make the hairs stand on end causing goose bumps.

if you want to test this out put your fingers on a surface with you palm in the air, put your middle finger off the surface and up to your palm, now tap all your fingers indipendantly.Eat Uranium said:The muscles are in your forearm.

Alright, if you want to see it this way I guess you could say that there are no muscles in the fingers. Would have been clearer to say "no independent muscles" or something.Eat Uranium said:The muscles are in your forearm.

A metre is defined as the exact distance light travels in 1/299,792,458th of a second.
The nearest star to us (other than Sol) is Proxima Centauri. It is 4.2 light years away (a distance of 39.73506798483936 quadrillion metres, which is approximately 24.6359232 trillion miles). Travelling at a speed of 100,000 miles per hour, it would take approximately 28,104 years to reach it.
