What size asteroid would burn up in the atmosphere?
Space rocks smaller than about 25 meters (about 82 feet) will most likely burn up as they enter the Earth’s atmosphere and cause little or no damage.
How fast would an asteroid hit the earth?
What Happened During the Impact? Asteroids hit Earth typically at high speeds of 16 to 32 km/sec (10-20 miles/sec).
What would happen if a meteorite will hit the earth?
With an asteroid hitting the Earth; dust and smoke rising in the atmosphere prevents sunlight from reaching our world and causes the total temperature to drop. This event can lead to the death of many living things. If an asteroid the size of an apartment hits Earth, this blow could possibly destroy a small city.
What would happen if a comet hit Venus?
If it were to hit Venus, at its current velocity and mass, the impact could very well ignite the atmosphere especially considering that at day it is approximately 400°C and the impact would be around 500,000 megatons. So the surface of the planet would be vaporized.
What is the fastest comet ever recorded?
Comet Encke

| Earth MOID | 0.17 AU (25 million km) |
What if a comet hit the ocean?
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.

What would happen if a comet hit Mars?
According to NASA, the comet is likely 1-3 kilometers (0.6-1.9 miles) wide and traveling at 56 kilometers per second (125,000 mph). “It if does hit Mars, it would deliver as much energy as 35 million megatons of TNT,” added Yeomans. The result could be a warmer, wetter Mars than we’re accustomed to today.”
