The asteroid, named Florence, is an almost 3-mile-wide rock that passed about 4.4 million miles from Earth

Was there really no available Russian satellites to help put this on a collision course with Earth? Surely there's some sort of spacelaservoodoothingymajig that could pull a rock like that towards us.

Based on research 800 trillion terajoules of energy implanted internally in the Asteroid wood destroy it. It wood take a small team of deep-sea oil drillers. Trained as Astronauts and in return we all wood end up watching a terrific meteor shower.

So... basically the premise for 'Armaggedon', but our heroes help destroy the earth instead. I like it. Now that we know what we need, when's the next one coming around?

Actually a team of Grad students wrote a paper discounting a nuke device as probable.
Next as KNOWN as often Asteroids are discovered by the pros and amateurs so not all are known but for what is known

On Oct. 12, 2017, the asteroid 2012 TC4 is slated to whizz by Earth dangerously close. The exact distance of its closest approach is uncertain, as well as its size. Based on observations in October 2012 when the space rock missed our planet, astronomers estimate that its size could vary from 12 to 40 meters. The meteor that exploded over the Russian city of Chelyabinsk in February 2013, injuring 1,500 people and damaging over 7,000 buildings, was about 20 meters wide. Thus, the impact of 2012 TC4 could be even more devastating. "It is something to keep an eye on," Judit Györgyey-Ries, astronomer at the University of Texas' McDonald Observatory, told astrowatch.net. "We could see an airburst maybe broken windows, depending on where it hits."
The house-sized asteroid was discovered on Oct. 4, 2012 by the Pan-STARRS observatory in Hawaii. Week later, it gave Earth a close shave when it passed the planet at the distance of 0.247 LD (lunar distance), or 94,800 km. 2012 TC4 is an elongated and rapidly rotating object and has been known to make many close approaches to Earth in the past. Now, the scientists try to determine the exact path of 2017 fly-by and the probability of a possible impact.
"It has a 0.00055% cumulative chance that it will hit," Györgyey-Ries said. "The fact that the MOID [minimum orbit intersection distance] is only 0.079 LD flags it as a possible impactor. However it is just the smallest possible distance between the orbits."
"There is one in a million chance that it could hit us," Detlef Koschny, head of the Near-Earth Object (NEO) Segment in the Space Situational Awareness (SSA) programme office at ESA, told astrowatch.net. He also tried to estimate the exact size of the celestial body. "The size was estimated from the brightness, but we don't know the reflectivity. So it could be smaller or larger, assume from 10 m to 40 m. A 40 m iron object would go through the atmosphere and make a crater; a 10 m rocky object would be hardly noticed."
Makoto Yoshikawa of the Japanese Aerospace Exploration Agency (JAXA), member of NEOs Division at the International Astronomical Union (IAU) is convinced that the asteroid poses no danger to Earth. "The distance is very small. But this distance does not mean the collision," he said.
NASA's Asteroid Watch has assured there is no chance this asteroid will hit our planet, but Györgyey-Ries admits more observations are needed to mitigate the uncertainties.

Do you think we'll be ready in time to move TC4 as it nears? It's only fitting that TC ends the world.
