Collisions of the Early Solar System [4K]

How did Earth get its moon? Why is Mercury so close to the sun? Why does Uranus orbit on its side? And what makes Pluto unique among the other worlds? The answers to all of these questions are the many collisions that ravaged the early Solar System. Each of our neighbouring worlds bears scars which echo their violent past, from the many craters of the moon's battered surface, to the sideways rings of the planet Uranus. And in this video, we will examine a number of the most significant collisions, which each played a pivotal role in building up the Solar System as we know it today.
Last time out, we talked about the history of Earth, but with one key detail missing- the formation of the Moon. And so perhaps that would be a good place for us to start, as we revisit the many collisions of the early Solar System.

If you haven't done it already, a deep-dive into our solar system's dwarf planets would be neat

[@Akash-uq8wg]

If waterice on the moon surface gets exposed and solar radiation hits it. Will it explode. So is mining on the moon realistic? Because there's bound to be sub terrain ice.

[@highbrbieee]

supermassive black holes

[@lukehornbeck]

Would be fascinating imo to see a full one on asteroids and comets, compositions, how much water we think they brought, and overall locations/futures relative to us.

[@portugalforme1198]

How about an examination of the Roche limit, what would happen if the moon came closer to Earth? Differential gravitational forces would rip it apart. As would have happened in any impact involving Earth and Theia, depending on the closing speed, Earth's gravity may have had time to pull Theia apart before they collided. Thanks for taking the time and putting in the effort to post these informative videos.

I'm so glad that you brought back the "What Rammed Into Uranus?" title for one of the chapters 😂

[@sea_space]

I actually had the idea for this video before the short, the two shorts came from my original idea of wanting do a video that linked the moon’s collision with Uranus’s collision. But of course to market Uranus you gotta make it about Ur Anus 😂

Perhaps in a Part 2 you might discuss the proposed giant impact that may have caused the differential between Mars' hemispheres. The formation of the South Pole-Aitken Basin on the Moon would be another interesting subject.

[@robertwokosin1293]

You might add Venus and the proposed impact that gave it it's retrograde spin.

Makes me think the vigintillion number of planets out there in the universe, orbiting the octodecillions of stars in the tredecillions of galaxies. The earth already seems mysterious for us enough, we have only explored 5 percent of the ocean, let alone planets in our solar system. We are truly smaller than quarks when compared to the universe
