Asteroid 2003 SD220 Sleighs by Earth on Christmas Eve
Arecibo Puerto Rico (SPX) Dec 28, 2015
During the month of December, the Planetary Radar Group at Arecibo Observatory has observed near-Earth asteroid (NEA) 2003 SD220, which will have its closest approach to Earth on December 24. Although designated as "potentially hazardous," this asteroid will be 28 times further away than our Moon and therefore poses no present danger to Earth. There is neither chance of impact nor any other effects due to its flyby despite unfounded predictions from online media. The NASA-funded planetary ra ... read more
