Potentially Hazardous Asteroid 2015 TB145: an image (22 Oct. 2015)
While waiting for its minimum distance from the Earth, at Virtual Telescope we imaged potentially hazardous asteroid 2015 TB145 safely approaching us. This 500-meters large asteroid will be at about 500.000 km (1.3 lunar distances from us) next 31 Oct., this making it the closest approach by an asteroid that big since 2006 (and the first known similar size asteroid to come that close will be 1999 AN10 in 2027.
The image is the average of two, 120-seconds exposure, remotely taken with PlaneWave 17″+Paramount ME+SBIG STL-6303E robotic unit part of the Virtual Telescope. The asteroid is the little dot in the center, marked with two white lines. At the imaging time, the object was at about mag. 17.8 and at about 26 millions km from our planet.
On 31 Oct., at 00:00 UT, the Virtual Telescope will show the asteroid live, online: learn more here!
