One already has. 2012 DA14 passed about 17,000 miles from earth on February 13, 2013.
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.
No. The asteroid has passed, having missed Earth by about 17,000 miles. That's fairly close, but scientists new it would miss by about that much.
No, an asteroid cannot destroy earth, but a large enough asteroid can have devastating effects on the life on Earth
An asteroid is space debris made up of rock and metal and can range drastically in size. When an asteroid makes a collision course for Earth, it is called a meteor. A meteor that manages to hit the Earth is called a meteorite.
August 2027 has no particular significance for that asteroid. In August 2027 an object called 1999 AN10 will pass close to Earth and be the biggest since 2015 TB145.
It was in February 2012 about a year before its close approach to Earth in February 2013.
The old saying "a miss is as good as a mile", although if an asteroid were to pass within about 300 miles of the Earth, it would definitely be "too close for comfort"! A "safe" distance might be anything greater than about 25,000 miles, which would prevent it from colliding with our geosynchronous satellites as well.
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.
It does not have an actual name, but it has the designation 2012 DA14
Apophis is an 885 foot diameter asteroid that will pass by Earth on April 13, 2036. The odds of it hitting the Earth are calculated to be 1 in 48,000. Keep in mind that the asteroid that crashed into Chicxulub, Mexico wiping out the dinosaurs was 6 miles wide,nearly 36 times larger.
Yes, if the asteroid is captured by the Earth's gravitational pull.
