Potentially Hazardous Asteroid (52768) 1998 OR2: new image and movie – 10 Apr. 2020
Here it is a new image of the Potentially Hazardous Asteroid (52768) 1998 OR2, slowly brightening and safely approaching us. On 28 Apr., we will show it live, online.
The image above comes from a single 300-seconds exposure, remotely taken with the “Elena” (PlaneWave 17″+Paramount ME+SBIG STL-6303E) robotic unit available at Virtual Telescope. The asteroid is in the center of the image, visible as a sharp dot of light, marked with an arrow. The telescope tracked the apparent motion of 1998 OR2.
Using 89 images collected back to back, we made this animation: the asteroid seems to move across the stars
When we imaged it, asteroid 1998 OR2 was at about 15 millions of km from us. This 1.8 – 4.1 km large asteroid will come as close as 6.3 millions of km from us next 29 Apr., – more than 16 times the average lunar distance: it will NOT hit us! – becoming bright enough to be seen with modest optical equipment, if you know where to look. We will show it live, online.
