Space is super weird. It smells funny, it’s full of odd shapes, and it’s much more gross than you could have ever imagined. There are so many surprising facts about outer space that just seem made up, like the fact that it smells like raspberries, or that Saturn’s rings disappear. As weird as that space trivia sounds, it’s 100% true. Historical theories about space are absolutely bonkers, but as bananas as they sound, they’re not far off from some of the surprising space facts that you’ll find on this round up of super weird ephemera about the solar system.

Outer space is super creepy. It’s an empty expanse of dust, gaseous beings, and dead satellites floating in their own graveyards. You may find many of the following space facts to be awe inspiring, but there are a few pieces of knowledge on here that will definitely make you change your mind about booking a ticket to Mars any time soon. Unless you like the idea of midnight ice bursts and the possibility of suffocating in your sleep.

Astronauts Run The Risk Of Suffocating In Their Sleep


Throw all of your childhood dreams about going to space in the trash, because the life of an astronaut sounds horrifying. Not only do astronauts have to lead a celibate existence, but if you don't choose your sleep spot carefully, you can suffocate while you take a cat nap. Astronauts tend to sleep under ventilator fans to make sure they can keep the air moving. If they don't do that, they run the risk of surrounding themselves with a bubble of carbon dioxide that can choke them to death. It's weird that no one at NASA has solved this problem yet.

If Two Pieces of The Same Type Of Metal Touch In Space, They'll Be Permanently Welded Together


It's rare that something is so weird, terrifying, and cool at the same time, but the concept of cold welding manages to be one of the most confounding things about space. Cold welding, also know as contact welding, occurs in vacuums when the atoms of different items touch and because the atoms don't realize that they belong to different pieces of metal, they actually stick together forever. You can technically accomplish this on earth, but you would need to construct a vacuum with a super clean room and use tools coated to prevent them from sticking to whatever you're working on.

99% Of Our Solar System’s Mass Is The Sun


Defining the weight of the solar system, a complex and amorphous expanse of matter, is almost impossible. Planets, moons, and stars aren't weighed by their weight, but instead their weight is determined by their gravitational force. For instance, the Earth weighs 5.972 x 10^24 kg. That's a lot of kilograms! But it's still nowhere near as close as the sun, which makes up 99% of all the mass in the Solar System. The core of the sun is a dense collection made up of hydrogen, helium, carbon, nitrogen, and oxygen all swirling together in one massive nuclear fusion

The Apollo Astronaut’s Footprints Will Stay On The Moon For At Least 100 Million Years


Neil Armstrong and Buzz Aldrin made quite the impression on the moon when they took their first steps across its gentle white face. You've probably seen photos of their footprints crunched into the moon's surface and thought, "What's the big deal?"

Unlike footprints on Earth that are eventually done away with by wind, rain, and general erosion, the Apollo 11 footprints will be there for millions of years. There's no wind on the moon to blow the footprints away, and the lack of an atmosphere means that all of the water on the moon is ice. Those footprints are there to stay until the moon explodes or a meteor smashes into its surface.
