![]() When that happens, it will be a bad place for trickster gods, or anyone else, to hang out.Loki episode 3 - out now on Disney+ and Disney+ Hotstar - felt very much like an instalment of The Mandalorian. Moreover, there’s some evidence that the moon will collide with the Earth in the distant future. ![]() The leftover material coalesced into the Moon. When the solar system was young, a Mars-sized object is believed to have collided with Earth. In fact, it’s believed this happened on Earth once before. Pieces of the moon would then spread out creating a ring around the planet, not unlike the rings of Saturn. In short, as the planet approaches Lamentis-1, there comes a point when the gravity of the planet would rip the moon apart. The Roche limit is the point at which tidal forces overcome the internal gravity holding a body together. That threshold is known as the Roche limit. As the planet and moon move nearer to one another, the side of the moon closer to the planet would be pulled upon by the planet’s gravity more strongly than the far side.įor a while, the moon’s internal gravity will outweigh external forces but there is a threshold beyond which that’s no longer true. It’s the moon's internal gravity that holds it together as a single object, rather than a collection of gravitationally attracted but distinct objects. That is, of course, if the moon held together at all. Anyone on the surface would feel themselves getting lighter and lighter until eventually, they fell up, into the sky, toward the encroaching planet. Because the effects of gravity are determined both by mass and proximity, the nearer the parent planet got to Lamentis-1, the more it would pull on the moon and everyone on its surface.ĭepending on the planet’s size and proximity, it’s possible that its gravity would begin to overwhelm that of the moon. But if a planet and moon began getting closer to one another, things would change. Under ordinary circumstances, this doesn’t have much of an impact on any people living on the surface. In the simplest terms, anyone standing on the surface of a moon would feel the gravity of that moon most strongly, but they would also be pulled upon by the parent planet. ![]() In short, if you didn’t get off the surface of Lamentis-1, you’d wish you had long before the planet actually made contact. Io is a violent place filled with environmental extremes owing entirely to gravitational pressures. Io’s most consistently active volcanic area - observations have confirmed its continued activity since at least March 1979 when Voyager 1 passed by - is appropriately named Loki Patera, a regularly erupting lava lake 126 miles (202 kilometers) in diameter. These forces deliver a lot of frictional heat resulting in staggering volcanic activity. Each of these objects is interacting gravitationally and Io is pushed and pulled constantly. The gravitational situation on Io is complex, owing to the pure size of the parent planet as well as the other 78 moons. We need only look to Io, one of Jupiter’s moons, for proof. Those same tidal forces would heat up the interior of the planet causing increased volcanic activity and earthquakes. The tidal forces would cause incredible shifts in the world’s oceans, causing sky-high waves and pretty quickly making the surface at least hugely inconvenient to live upon. If the moon were much nearer, the effect of its gravity would be felt more strongly. This shifting pressure causes the tides and contributes a certain amount of heat energy to the planet by way of geological friction. The force of the moon’s gravity shifts as Earth rotates and as it orbits the planet. While the moon’s gravity does pull on you, it’s such a small fraction of the total gravity you feel (something like 0.0003 percent) as to be imperceptible. It is much smaller than the Earth and pretty far away. On the surface of the Earth, we almost never think about the gravitational impact of the moon. In reality, the situation on the surface would be pretty violent and the cutoff for leaving would have happened long before the planet descended low enough to crush buildings. At least some of the residents are sitting in their homes, calmly waiting to be smooshed. Other than that, however, the moon seems to be holding up pretty nicely. Bits of celestial rubble constantly pierce the atmosphere, pummeling the moon’s surface in a barrage of planetary buckshot. While Loki and Sylvie are desperately trying to find a way off of Lamentis-1, the sky is filled with the imposing view of its parent planet bearing down.
