On Christmas Eve, a gargantuan asteroid is on track to be visible from our planet via telescope.
But not to worry: There’s no danger of a Christmas Day apocalypse. The 3-kilometer-long asteroid (named 163899, or 2003 SD220) will be sailing by at a safe distance of 6.7 million miles.
The director of Northern Ireland’s Armagh Observatory, Mark Bailey, told AFP that while it’s not necessarily an “Earth-grazer,” it’s near enough that “you could expect several such encounters with objects of that sort of size every year—so maybe every couple of months you would get one coming that close, and of the same size.” He also noted that large-body collisions with Earth are rare, only occurring about once every 100,000 years.
If you miss this asteroid’s celestial dance this time around, you can catch it again in 2018, and again in December, according to a NASA report. Popular Science notes that the data researchers gather from the holiday asteroid is critical, as preliminary plans are in place to land aircraft on asteroids in the near future.
However, the next time an asteroid is expected to get somewhat uncomfortably close to Earth is 14 years from now, in April 2029, when the asteroid Aphophis is scheduled to pass about as close as the Moon and to be visible sans telescope.
