The space rocks just keep a comin’. This time, newly discovered 2014 DX110 will pass just 216,000 miles from the Earth today around 3 p.m. CST. Break out those stopwatches – this 98-foot-wide bugger will be speeding by at 32,076 mph.
Bear in mind that close flybys of Earth are fairly routine with an average of one or two asteroids a month passing within the moon’s distance of our planet. 2014 DX 110 is no exception and poses no harm to Earth. What makes the flyby of interest is the very thing that makes it so routine. We now see so many of these lively asteroidal sprites thanks to better equipment and multiple sky surveys. This one was captured by the Pan-STARRS1 survey from Maui, Hawaii on Feb. 28.
You can also watch the flyby on live webcast with commentary courtesy of the fine folks at the Virtual Telescope Project. The show starts at 3:30 p.m. CST (4:30 Eastern, 1:30 Pacific). If you miss it, the group plans another live Webcast when 2014 CU13 zips by on March 10. While that asteroid’s larger at 590 feet (180 meters), it will be considerably farther at 1.86 million miles.
2014 DX110 belongs to the same class of near-Earth asteroids from whence came the mighty meteorite that exploded over Russia last February 15. These Earth-crossings bodies are named for asteroid 1862 Apollo, discovered in 1932. Apollos have orbits that take them very near the Earth with the potential for a future collision.
Don’t worry too much about DX110. According to NASA’s Earth Impact Risk Summary site, it has a 1 in 10,000,00 chance of hitting the planet on March 4, 2046. But since this estimate is based only on 28 observations spanning just under 4 days, future observations will probably lessen that barely significant probability even more.
Too bad a close approach won’t mean a bright point of light. The asteroid isn’t expected to get any brighter than magnitude 15, putting it well beyond the reach of beginners and even many amateurs. Why? It’s just too small. You’ll need at a 12.5-inch telescope and a darn good map to track it, since DX110 will be dashing across the sky.
Most likely you’ll be pouring another cup of coffee or trying not to yawn too loudly at a meeting when 2014 DX110 goes whizzing by later today. Or maybe you’ll get fired up and dial up a live view at the link above. Know this. Despite over 4.5 billion years of time to clean up its act, the solar system still has enough leftover rocks and snowballs to rattle the nerves. Just a little.
UPDATE March 5: Another just-discovered asteroid, 2014 EC, will pass considerably closer to Earth tomorrow at 3 p.m. – hey, how about that, same as today’s flyby. Predictions call for it to miss us by 48,000 miles. Again, there’s no threat of a strike. Asteroids can pass very close to the planet without concern about being “sucked in” by gravity because they’re moving forward in their orbits far too fast. The Virtual Telescope Project will also be featuring a live webcast of 2014 EC’s flyby.
(Note: The webcast link for 2014 EC is correct but I’ve noticed it doesn’t connect on occasion. I’ll update again if the link changes. You can also check out SLOOH’s live-cast HERE.)
