1990 it created a very big crater
The last meteor to enter Earth's atmosphere was probably sand to pebble sized and burned up in the atmosphere within a second or two, producing a streak of light across the sky that a lucky person might have seen if they looked up at the right time.
No, the meteorite that caused the Barringer Crater in Arizona landed about 50,000 years ago had nothing to do with the ice age. The present ice age started about 2.6 million years ago and the crater was formed mid-way during the last glaciation.
No. A meteor cannot hit the earth: meteors burn up in the earth's atmosphere. A meteorite, indeed slots of them, hit the earth last night. Astronomers estimate between 36 and 166 meteorites larger than 10grams fall to Earth per million square kilometres each year. Over the whole surface area of Earth, that translates to 18,000to 84,000meteorites bigger than 10grams per year. That is a minimum of at nearly 50 a day.
Small meteors hit the Earth every minute of each day. Larger meteors, big enough to be visible, hit the Earth several times each hour. In a "meteor shower", you may see over a hundred meteors an hour. Big meteors, big enough to hit the Earth, happen a few times every day. There are dozens of meteorite museums all over the country. Really big meteors, enough to cause a lot of damage, are fairly rare, fortunately. The last REALLY big meteor landed in Siberia, 100 years ago; it caused as much damage as an atomic bomb! Fortunately, very few people lived in Siberia back then.
A meteor cannot hit the earth: meteors burn up in the atmosphere. The last meteorite to hit the earth was too insignificant to be named. Astronomers estimate between 36 and 166 meteorites larger than 10grams fall to Earth per million square kilometres each year. Over the whole surface area of Earth, that translates to 18,000to 84,000meteorites bigger than 10grams per year. These are simply too insignificant to merit a name!
No person has ever landed on Mars. The only body outside of earth on which people ever landed is the moon. The last time that happened was 38 years ago. Mars is 180 times farther away. No manned missions to Mars are planned yet.
We call the fireball caused by friction and compressive heating a "meteor" as it passes through the atmosphere. The fragments that last long enough to strike the ground are called "meteorites".
No astronaut has ever landed on Saturn.
There was one significant asteroid impact in 1908 - the Tunguska event. It is possible that smaller asteroids hit Earth after that. There was a smaller asteroid/meteor impact more recently - the Chelyabinsk event in 2013.
The most recent confirmed meteorite fall in Ohio was in 1994 when a meteorite landed near the town of Morristown. However, there have been reports of smaller meteorites or meteorite fragments found more recently in Ohio.
Many things can happen if an asteroid hit the earth. Here is a list of a few consequences. There could be an explosion when the asteroid hits the earth. There could also be a tsunami if the asteroid landed in the water. Another possible consequence is a global firestorm. Another possible problem is Acid Rain. The last and final problem from this small list is temperature effects.
Well, as of the time of this writing, it is now 2016, and Earth hasn't been destroyed yet - so no.
