Halloween 2016 Brings Our Planet Another Close Encounter
Not another closer call from our asteroid friends, but that’s what it looks like.
This time we have news about asteroid 2015 TB145 which is a sizable asteroid that is hurtling through space at speeds of over 78,293 mph , and it’s heading this way. Discovered only 10 days ago, the asteroid has caught the attention of scientists at NASA because on October 31 (Halloween night – you can’t make this stuff up), it is expected to draw closer to Earth than anything this size has since July 2006.
Don’t panic friends and tech blog readers. When NASA says “close”, they are talking “relatively close”, which in this case means 1.3 lunar distances, or about 310,000 miles from our comfy little planet.
“This is the closest approach by a known object this large until 1999 AN10 approaches within 1 lunar distance in August 2027,” a NASA report states. “The last approach closer than this … was by 2004 XP14 in July 2006 at 1.1 lunar distances.”
Detected on October 10 by the Pan-STARRS I survey in Hawaii, which employs several astronomical cameras and telescopes from around the world to identify potentially threatening near-Earth objects, asteroid 2015 TB145 is estimated to be between 918 to 2,034 feet in diameter.
NASA reports that we have had closer encounters recently, but not by something on this scale. In 2013, Russian motorists filmed a very large meteorite as it burn up in Earth’s atmosphere back in 1908, and crashed into a Russian forest.
According to NASA’s Near-Earth Object Observations Program, as of October 16 2015, 13,251 near-Earth objects have been discovered, 877 of which are asteroids with a diameter of approximately 1 kilometre or larger. Some 1,635 of these have been classified as Potentially Hazardous Asteroids (PHAs).
If all of this makes you a little nervous, don’t worry. NASA suggests that none of the asteroids or comets that they have identified will come close enough to impact Earth anytime in the foreseeable future. “All known Potentially Hazardous Asteroids have less than a 0.01 percent chance of impacting Earth in the next 100 years,” they reported back in August.
For me, the scarier part is that NASA did not spot 2015 TB145 until less than two weeks ago!
