Asteroid TX68 is coming! OK, it's probably gonna miss... but maybe not! Asteroid TX68, from it's name 2013 TX68 was discovered in 2013. It is supposed to approach closer than anything else recently, at .044 times the Lunar distance, or about 11,000 miles. Not sure why they use LD as a measurement because LD changes all the time, but so it goes... Comments or thoughts are always appreciated!
