![]() ![]() ![]() In fact, we’ve visited nearly every major body that orbits our sun. Human Spacecrafts Have Visited Every PlanetĪfter exploring space for over 60 years, we have managed to get some sort of spacecraft to flyby every single planet within our solar system. ![]() While Earth is the only planet known to have stable bodies of liquid water on its surface, water is thought to exist as liquid beneath the surface of some planetary bodies, similar to groundwater on our planet. As we’ve explored space more, and come to better understandings about its composition, we are increasingly realizing that water and ice are fairly common throughout our solar system. Water and ice elsewhere in space was considered rare. Ice and Water Are Everywhereįor a long time, people thought water was one of the unique features of Earth that made our planet special. Compare this to Earth, where the fastest winds are only 10-20% if the planet’s rotational speed. What is unique about this, is that these winds travel up to 60 times faster than the planet itself rotates. These clouds can circle the planet every four to five Earth days. The entire atmosphere of Venus circles around the planet at rapid speeds, with winds reaching speeds of 186 mph at the top of clouds. But perhaps the craziest aspect of Venus is its wind. Venus Has Insane WindsĮxtreme temperatures, clouds of sulfuric acid – Venus is pretty insane in general. For some perspective, if it was on Earth, Valles Marineris would stretch from Los Angeles to the Atlantic coast. Stretching across nearly one fifth of the circumference of Mars, this canyon system is among the largest in the solar system. If you thought the Grand Canyon was impressive, wait till you see Valles Marineris. Aside from Earth, Io is the only known body in the solar system to have observed active volcanoes. The volcanic activity is a result of Io being stretched and squeezed as it orbits Jupiter. Jupiter’s fifth moon, Io, is covered with volcanoes. Scientists think this tilt might have resulted from a massive impact in the past, or perhaps many successive collisions. In other words, its north and south poles can be found where most other planets have their equators. Among the most interesting aspects of Uranus is that it is titled completely on its side. But crude jokes aside, the planet is pretty fascinating. It’s every school child’s favorite planet. Here are 20 interesting astronomy facts that you might not know. And sometimes, the stories associated with these findings are fascinating in their own right. Nonetheless, in all the years we’ve spent gazing up at the night sky, we still have managed to find out some pretty interesting things. Sure, as humans, we’ve made our share of astronomical discoveries, but given the grand scale of the universe, there is still so much we have yet to learn and understand. It is even more bizarre when you consider just how little we know about it. Space is a crazy place with all types of mysteries held within it. ![]()
