Asteroid 2016 XW20 to flyby Earth on December 13

Newly discovered asteroid 2016 XW20 will flyby Earth on December 13, 2016, passing just 1.8 LD (691 200 km / 429 491 miles) from the surface of our planet at a relative velocity of 8.42 km/s. The closest approach is expected at 00:18 UTC.

This asteroid was discovered on December 8, 2016 by Mt. Lemmon Survey. 2016 XW20 is an Apollo-class near-Earth object with an estimated size of 13 - 29 m (42.6 - 95 feet). For comparison, estimated size of Chelyabinsk object of February 2013 was 20 - 40 m (65 - 131 feet). Pieces of that one survived the entry and the explosion it produced as it raced toward the surface injured over 1 000 people.

I saw a fireball strike close to or on the Ohio State University main campus in Columbus, Ohio at 3:23 AM on December 13, 2016. It had short bright red flames coming out its trail. Somewhere from the OSU main 'Oval' to Neil and King Avenues there is an astroid. I could not tell the size of the ball other than it was larger than a basketball and smaller than half a Volkwagon Beetle. A close vector of its landing site can be drawn from 2519 N High St Columbus, Ohio through the intersection of Neil and W Norwood Avenues. Its landing spot would be somewhere beyong that intersection, probably on the OSU campus up to the King Av area.
