Asteroid 2013 TV135 – A Reality Check
http://www.nasa.gov/mission_pages/asteroids/news/asteroid20131017.html
Newly discovered asteroid 2013 TV135 made a close approach to Earth on Sept. 16, when it came within about 4.2 million miles (6.7 million kilometers). The asteroid is initially estimated to be about 1,300 feet (400 meters) in size and its orbit carries it as far out as about three quarters of the distance to Jupiter’s orbit and as close to the sun as Earth’s orbit. It was discovered on Oct. 8, 2013, by astronomers working at the Crimean Astrophysical Observatory in Ukraine. As of Oct. 14, asteroid 2013 TV135 is one of 10,332 near-Earth objects that have been discovered.
That’s why I want to see the asteroid miners out there getting to work. When an asteroid does pose a threat, they’ll likely get the contract to move it to a safer orbit.
On a side note, think of the possibilities of asteroid mining combined with the printing of large scale structures in space.
