Do thoughts about an endless sky above start bothering you minutes before you should fall asleep? Black holes make you unexplainably anxious? Are extraterrestrials real? As vast and unexplored as space is, there sure are plenty of cool scientific facts to put your mind at rest. And, to save you (and ourselves) from another sleepless night spent wondering about the miracles (or science) of the universe, we've rounded up some of the most important space facts in this fun little article. 

From the length of the day on various planets in our solar system to diamond showers and the actual size of heavenly bodies compared to a unit of measurement we all understand - football stadiums - all the basics are covered in our facts about space. After the groundwork comes the more complex questions about gaseous compositions, thermodynamics, and such - no stone unturned in these cool facts about space! And, the further we dig into the core topics of our universe, the more at ease you'll probably start to feel. At least we do desperately hope that these fun facts about space will soothe you and calm you instead of scrambling your thoughts on black holes even further.

Now, jump into your moon boots, and let's explore the universe of cool space facts together! Although presumably, they should be somewhere higher up, the interesting facts are instead a bit further down. Once you are there, rank the bits of info by their unexpectedness and share this article with your friends!

THEORIES: The Fission Theory: This theory proposes that the Moon was once part of the Earth and somehow separated from the Earth early in the history of the solar system. The present Pacific Ocean basin is the most popular site for the part of the Earth from which the Moon came. This theory was thought possible since the Moon's composition resembles that of the Earth's mantle and a rapidly spinning Earth could have cast off the Moon from its outer layers. However, the present-day Earth-Moon system should contain "fossil evidence" of this rapid spin and it does not. Also, this hypothesis does not have a natural explanation for the extra baking the lunar material has received. The Capture Theory: This theory proposes that the Moon was formed somewhere else in the solar system, and was later captured by the gravitational field of the Earth. The Moon's different chemical composition could be explained if it formed elsewhere in the solar system, however, capture into the Moon's present orbit is very improbable. Something would have to slow it down by just the right amount at just the right time, and scientists are reluctant to believe in such "fine tuning". Also, this hypothesis does not have a natural explanation for the extra baking the lunar material has received. The Condensation Theory: This theory proposes that the Moon and the Earth condensed individually from the nebula that formed the solar system, with the Moon formed in orbit around the Earth. However, if the Moon formed in the vicinity of the Earth it should have nearly the same composition. Specifically, it should possess a significant iron core, and it does not. Also, this hypothesis does not have a natural explanation for the extra baking the lunar material has received.
