It could be possible that one day, billions of years from now, the Earth will stand still. But chances are good that other events that will occur before that, such as the sun swallowing up the planet. With that being said, there isn’t a chance that the Earth will suddenly stop spinning anytime soon. But let’s just assume for a moment that the Earth did suddenly stop rotating, and take a look at what would happen to us, and the planet.
Our planet spins at its equator 1000 miles per hour as it orbits the sun. But, as you get closer to the poles, the rotation is slower. Without this rotation, life as we know it wouldn’t be possible. It is said that billions of years ago, our planet used to spin much faster than it does now. In the beginning of our young solar system, an unknown planet or large celestial body collided with the Earth, and in that collision, the Earths alignment and rotation were changed, and the moon was formed. Since then the Earth’s rotation has been slowing down. It is said that the moon used to also spin faster than it does now before it became tidally locked with the Earth.
Tidal locking is the name given to the situation when a moon or planetary object’s orbital period matches its rotational period. Coincidentally, it is the same fate that affects every single large moon orbiting a planet. A great example of this is our own Moon. In our early Solar System, both the Earth and the Moon rotated independently of each other.
But the Earth’s gravity grabbed onto the tidal bulges and slowed down the rotation of the Moon. To compensate for the loss of momentum in the system, the Moon drifted away from the Earth to its current position, about 230,000 miles away.
How Long Would It Take to Fall Through the Earth? Subscribe: CHECKOUT THIS COOL CHANNEL: Life Noggin: What Would Happen If The Earth Stopped Spinning? Have you ever wondered how long it would take to fall through the Earth to get to the other side? And not by taking some special driller vehicle like in the movie ‘The Core’, we’re taking about jumping into a hole that goes from one side of the Earth to the other. And while this entire experiment might sound like a waste of time, this scenario is often presented to introductory physics classes using a "gravity tunnel" model, which is a tube drilled from one side of the Earth to the other right through the center. The answer that’s been taught for nearly a half-century for how long the fall would take is an estimated 42 minutes and 12 seconds. But this answer has turned out to be wrong because previous calculations in the experiment assumed the planet was uniform. That was until someone by the name of Alexander Klotz, a graduate student in physics at McGill University in Montreal, Canada, predicted that an object should fall through Earth in 38 minutes and 11 seconds, instead of the 42 minutes and 12 seconds that was previously predicted. The difference is that his planetary reference model is based on seismic data. Speaking of seismic data, a lot of the data we have on the inner structure of the Earth comes from seismology, which is data collected from Earthquakes traveling through the ground. Even if there was such a hole you could jump through to get to the other side of the planet, you might not be able to get there for a couple of reasons. In fact, you might be trapped in the hole forever after you jumped in, and we’ll explain why.
We know what would happen if a meteor collided with the Earth, but what about the sun? Can it even be hit?

The Solar and Heliospheric Observatory (SOHO) is a joint NASA ESA mission to probe the corona, or outer layer of the sun's atmosphere. " What Would Happen If a Massive Comet Crashed into the Sun? "Most comets that brush past the sun end their lives in a whimper. But according to new calculations, a big enough comet that plunges into the sun should go out with a bang.
