No, an asteroid cannot destroy earth, but a large enough asteroid can have devastating effects on the life on Earth
No, if the Earth was destroyed by an asteroid we would not be living today.
Yes, the asteroid belt starts properly after the orbit of Mars.
Not without a telescope and detailed knowledge of where to look. They're tiny and not close to Earth.
Yes, if the asteroid is captured by the Earth's gravitational pull.
Probably not. I haven't seen any news about an asteroid about to strike Earth.
Theory suggests that it is a remnant of a large asteroid that struck the Earth
The asteroid belt is shaped like a donut. The earth and moon, mars, venus, mercury and sun are all in the hole in the middle.
No.
Technically, if it hits the Earth it's not an "asteroid", it's a "meteorite". And yes, meteorites hit the Earth all the time.
Which asteroid? depending on its size, an asteroid impact could be devastating for life on Earth, though life would recover somehow eventually.
Not just like that, it'll prefer to keep moving in its established track. It'd pretty much have to bump into another asteroid to change orbit radically.
