Depending on their speed relative to earth's own speed, their impact energy may be stronger than nukes!

Will an asteroid collide with Earth this year? Nasa reveals the FIVE space rocks that will come 'close' to our planet
Ron Baalke tweeted about 5 asteroids expected to come within 5 lunar distances
The first will be come on July 23, and will fly 3.15 lunar distances from Earth
The closest encounter will be on October 12 when an asteroid will fly within 0.15 lunar distances from our planet

It is a scene we all dread – an enormous space rock colliding with Earth, causing widespread chaos and destruction.
And experts have warned that the dreaded scenario could become a reality this year.
A leading astronomer from Nasa has tweeted a list of five known asteroids expected to fly scarily close to Earth within the coming year.

CLOSE ENCOUNTERS WITH EARTH Asteroid Date of encounter Distance from Earth (lunar distances) Estimated diameter (metres)
2017 BS5 23 July 2017 3.15 40-90
2012 TC4 12 October 2017 0.15 12-27
2008 WM61 03 December 2017 3.82 12-27
2017 DR109 24 February 2018 3.69 8-18
2004 FG29 02 April 2018 4.00 17-38
Ron Baalke, a space explorer at Nasa's Jet Propulsion Laboratory in Pasadena, California tweeted the worrying predictions.
He said: 'A list of known asteroid close approaches to Earth - less than five Lunar Distance - within the coming year', along with a table detailing the five asteroids.
According to Mr Baalke, the first close encounter will come on July 23, when Object 2017 BS5, which is predicted to have a diameter of 40-90 metres will come within 3.15 lunar distances (752,937 miles) with Earth.
The most worryingly close encounter is predicted to come on October 12, when Object 2012 TC4 will come within just 0.15 lunar distances (35,828 miles) with Earth, although thankfully the asteroid will only be 12-27 metres in diameter.
