When an asteroid hits the ocean, it's more likely to produce storm-surge-sized waves than giant walls of watery death. … "For coastal communities, at the moment we think these impact tsunami waves would not be much more hazardous than storm surges if the impact happens far off shore in the deep ocean," Robertson says.Nov 15, 2018
What if an asteroid hits the ocean?
Is it better for an asteroid to hit the ocean?
The larger the asteroid, the less it matters if it hits land or water. That said… other than nearby islands, the distance from major population centers would be greater if it hit in the middle of the ocean. Either way, a hit that large would cause an incredible catastrophic change to the atmosphere, globally.
Would an asteroid hit the bottom of the ocean?
If an asteroid were to slam into Earth, there's a strong chance it would end up at sea, with oceans covering roughly 70 percent of our planet's surface.
What if the asteroid that killed the dinosaurs hit deep water?
If the K-Pg 10km wide asteroid hit the deep oceanic floor instead, it would generated at least an enormous Tsunami ranging from dozens to hundreds meter high that would devastate all coastal zones but overall it should be still less threatening for biosphere than the collision with Yucatán Peninsula bedrocks.
What would happen if an asteroid hit the earth?
The more energy is released, the more damage is likely to occur on the ground due to the environmental effects triggered by the impact. Such effects can be shock waves, heat radiation, the formation of craters with associated earthquakes, and tsunamis if water bodies are hit.
What would happen if the moon was hit by an asteroid?
The Moon is very big, and any small object hitting it would have very little effect on its motion around the Earth, because the Moon's own momentum would overwhelm that of the impact. Most asteroid collisions would result in large craters and little else; even the largest asteroid known, Ceres, wouldn't budge the Moon.
What happens if an asteroid hits the sun?
Nothing will happen. The mass and the heat of the Sun are of such magnitude that even the biggest object in the solar system, Jupiter, hitting the Sun would cause just a momentary hiccup, and comets are actually tiny objects in the scale of the solar system.

How long did it take for Earth to recover from the asteroid?
The productivity of marine ecosystems in the North Atlantic took about 300,000 years to be restored. In the immediate area of the crater, however, life returned more quickly. Within the crater itself, marine organisms rebounded in less than 6 years.
