Potentially Hazardous Asteroid (199145) 2005 YY128 close encounter: a image – 09 Feb. 2023
Next 16 Feb. 2023, the large (diameter between 580 and 1300 meters) potentially hazardous asteroid (199145) 2005 YY128 will have a relatively close and obviously safe encounter with our planet. It will come as close as 4.6 millions of km, about 12 times the average lunar distance. Here it is our recent image.
The image above comes from a single 120-second exposure, remotely taken with the “Elena” (PlaneWave 17″+Paramount ME+SBIG STL-6303E) robotic unit available at Virtual Telescope. The telescope tracked the apparent motion of the asteroid, which was relatively slow at the moment.
At the imaging time, asteroid (199145) 2005 YY128 was at about 14 millions of km from the Earth and it was slowly approaching us. Weather conditions were poor, mainly hazy and cloudy, with a bright Moon rising. The asteroid was discovered by the Spacewatch survey, from Kitt Peak Observatory, on 30 Dec. 2005.
This 580m – 1300m large asteroid will reach its minimum distance (about 4.6 millions of km, almost 12 times the average lunar distance) from us on 16 Feb. 2023, at 00:46 UTC (source: Nasa/JPL). Of course, there are no risks at all for our planet.
