There is no "impact asteroid". An asteroid impact however is when an asteroid hits a planet or moon.
An asteroid is a type of a outer space rock/boulder. It can range in size from a grain of sand to Seattle to Portland 3 times. There are some so big they are considered "dwarf planets".
It is when an astriod impacts something or hits it
7.28 is the mathmatical term. Or 9.287.581
Jupiter :P
its a fifty fifty chance we just dont know It depends on how fast the asteroid is moving and the size of the asteroid. Then you have to consider the size of the planet (diameter, etc.), and its orbital speed, etc.
Billions of years ago a giant asteroid hit Saturn and got tangled up in the planet, when slowy Saturn spun around. The rings are the remain of the asteroid, ice and rock .
What happened when an asteroid hit the Earth is debatable but many scientists believe that this is what may have wiped out the dinosaurs. Some people believe that the asteroid created a dust cloud that covered the planet and caused a winter that froze most life.
Thousands of years ago, Uranus was hit by a massive asteroid.
An impact crater. The size depends on the mass and speed of the object and where it strikes
Impact, as in hit, sure.
Jupiter :P
It was not an asteroid. It was a planet. The name starts with an 'M'.
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.
2012 you will know first hand

An asteroid, being primarily composed of metals of vaious kinds, would melt and be vaporized long before making contact with the surface of the sun.

Yes, scientists have studied hundreds of 'nearby' asteroids and are quite confident that there are no asteroids capable of causing a major catastrophic impact currently on a collision course with our planet, at least in our lifetime.

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.
