Impact, as in hit, sure.
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.
There is no "impact asteroid". An asteroid impact however is when an asteroid hits a planet or moon.
Depending on how you define "asteroid", it could have been last night.But there was an impact in Africa last October that probably qualifies as an "asteroid"; it was a space rock big enough to be seen through a telescope, and it was detected 18 hours BEFORE it hit. It was the first time scientists had ever observed a space rock before impact.
An impact crater. The size depends on the mass and speed of the object and where it strikes
if its bigger than isle of man it would do a very big impact and damage
Perhaps in the event of a very large asteroid impact, but other than that, no.
That depends on which asteroid impact you are referring to, there have been several.The most recent, 65 million years ago, eliminated dinosaurs and several other species.
