I thought it would be fun for everyone to post any random facts they know (or something you Googled or whatever). It can be about anything as long as it's HP-appropriate. One player posts one fact. I'll start:

The Icelandic word for computer is tölva. It was coined in the '60s and is a combination of the words tala (to count) and völva (prophetess).

The largest known star has a greater diameter than the orbit of Uranus around the sun.

Cats can make about 100 different sounds, whereas dogs only make around 10.

According to data analyzed from Facebook posts, two weeks before Christmas is one of the two most popular times for couples to break up. However, Christmas Day is the least favorite day for breakups.

Did you know the earth's rotation is gradually slowing ? It will take about 140 million years to make a day 25 hours though.
Also a day in rotation of the earth is actually 23 hours, 56 minutes and 4 seconds. This is called a sidereal day; a full rotation relative to stars outside our solar system.
The 24 hour day is refered to as a Solar Day: This corresponds to how long it takes the earth to rotate once relative to the sun (how long it takes before the same point on earth faces the sun, i.e. how long it is between noon one day and noon the next day). It is 23 hours 59 minutes 39 seconds to 24 hours, 0 minutes, 30 seconds. Since the earth isn't entirely round (But has a bit of a bulge) this time varies depending of the time of the year.

Whoever said dogs can only make 10 sounds has never met Brienne. Or a husky for that matter. 

Tarantulas actually breathe through their abdomen. The organ is called a "book lung" and looks like two lighter colored patches on the underside of the spider.
