Near-Earth asteroid 2015 GA1 close to its minimum distance: an image (15 Apr. 2015)
A few hours from its closest distance from us, at Virtual Telescope we imaged near-Earth asteroid 2015 GA1 again.
The image above is a single 180-seconds exposures, remotely taken with the PlaneWave 17 + Paramount ME + SBIG STL-6303E robotic unit part of the Virtual Telescope. The robotic mount tracked the fast 155″/minute apparent motion of the asteroid, so stars are trailing, while the asteroid is perfectly tracked and visible as a sharp dot of light at the center of the image. It was brighter and much more faster than two nights ago.
At the imaging time, this ~20 meters large rock was at about 1.1 millions of km from the Earth and getting closer for its safe fly-by.
