So you want to know everything there is to know about the solar system? The first and most important question you might want to get out of the way is: what, exactly, isthe solar system? As Mental Floss editor-in-chief Erin McCarthy tells us, "It's a group of celestial bodies located within the Milky Way galaxy."
At the center of these bodies is the Sun, which is orbited by eight planets; more than 150 moons; and millions of meteoroids, comets, asteroids, and a handful of dwarf planets (sorry, Pluto). But it's the Sun—a.k.a. that shining, 4.5 billion-year-old star in the middle of it all—that accounts for 99 percent of the solar system's total mass. (Think about that the next time you're shading your eyes from its glare.)
In this all-new edition of The List Show, Erin is sharing nearly two dozen fascinating facts about our solar system, including the reasoning behind Pluto's demotion (blame it on Eris, the first known dwarf planet). For more out-of-this-world facts, you can watch the full episode below.

Groucho Marx once famously quipped that he'd never "want to belong to any club that would accept me as one of its members." Most people would probably say the same about the Martin-Baker Ejection Tie Club—a very exclusive, 63-year-old organization created specifically for individuals who have had their lives saved by an ejection seat. Currently, the club boasts more than 6000 members.
That's just one of the weird and wonderful clubs you'll learn about in our latest edition of The List Show. Join Mental Floss editor-in-chief Erin McCarthy as she hunts down the world's most unusual clubs (Extreme Ironing Bureau anyone?). You can watch the full video below.

Do you love the smell of rain? That clean, greenish aroma when rain drops hit dry ground? That's petrichor from the Greek Petra, meaning stone, and ichor, meaning the blood of the gods and goddesses. The term was coined by two Australian researchers in 1964 but became better known in 2011, when it popped up in an episode of Doctor Who.

Pins and needles. Crawling skin. The tingling sensation you get when your foot's asleep is known as paresthesia (you knew it had to have a -thesia in it) and there are dozens of causes.

Dysania means having difficulty getting out of bed in the morning‚ and not just in the way that makes you want to crawl back under the covers. Though it's not officially recognized as a medical condition, and can impact people's lives in a variety of negative ways.
The unreachable spot between your shoulder blades is your acnestis. Next time you can't reach an itch, ask a loved one to scratch your acnestis and see what they say.

You probably know that a palindrome is a word or phrase that reads the same way forward as it does backward. Like Mom or racecar or taco cat. There are whole books dedicated to these bad boys.

You might be familiar with palindromes, but you're probably less familiar with semordnilaps: a word that means one thing forward and another backward. Like stressed and desserts. Other examples include diaper/repaid, parts/strap and, of course, semordnilap itself read backward spells palindrome!

Silent letters, like in knight, fight, or Django, are aphthongs. This might be something that you already knew. (See what we did there?)

The person with your name who shows up in your Google search results is your Googleganger. Try not to be too annoyed that there's someone more internet famous than you. Instead, reach out politely to potentially gain a super surreal pen pal.

The bit at the end of the pencil that holds the eraser in place is a ferrule—though it's not just for pencils. Ferrules are any thin bracelet that fastens or reinforces a tube or pole that might split.

The uncomfortable feeling you get from overindulging? Crapulous. Though it sounds like a word invented by a middle-schooler in the 1990s, crapulous dates back to the 1530s when it was used to describe that gross nauseated feeling that you get from drinking too much.

The triangular bump on the inside corner of your eye is the caruncule. It's just skin covering sweat glands, which is why it, too, can get itchy.

Peladophobia is the fear of bald people. It's also the fear of becoming bald, which means it's most frequently suffered by balding people who are turning into the thing they fear the most.
Arachibutyrophobia is the fear of peanut butter sticking to the roof of your mouth. It's most likely related to pseudodysphagia, the fear of choking, so it's not as silly as it sounds. However, there's no known word for the fear of being forced to say arachibutyrophobia while peanut butter is stuck to the roof of your mouth.

Scandiknavery means deceit by Scandinavians. Like so many 20th century words, we have James Joyce to thank for that one. And of course, deceitful Scandinavians.

An agraffe is the wire cage that keeps a cork in a bottle of champagne. It's also called a muselet, which is apparently not a tiny muse.

Beer foam is called barm. It's a byproduct of the yeast hitting the buffet in your beer, and, yes, you can make really good bread from it.
31. The zings

Another name for a hangover is the zings. Encounter too many punts, agraffes, and barms in one night and you'll have the zings, which seems a rather peppy name for a hangover.

A word that can be its own antonym is called a contronym. For example, cleave can mean to sever or to cling. Off means deactivated, as in to turn off, but it also means activated as in "the alarm went off." Weather can mean to withstand or come safely through or it can mean to be worn away. If you seed your lawn, you add seeds but if you seed a tomato, you remove them.

A group of crows is known as a murder. They got the name in the 15th century because of their association with death. The term is also unfair and a bit outdated; ornithologists use flock for any kind of bird grouping, including crows. Food for thought!

A group of ravens is an unkindness. People 500 years ago were really not nice to crows and ravens.
