NEO Made a Close Flyby on Halloween Wow it was ~ 4.60 (Metaphorical) inches From a Basketball Size Earth

A 1  to 7 meters NEO made a close approache  on Halloween  it was ~ 4.60 (Metaphorical) Inches from a Basketball Size Earth. This asteroid discovered by the Catalina Sky Survey  and given the observer-assigned temporary designation. C0PPEV1(Now  2019 UN13) So far there is 18 observations from four observing stations over 3.7 hours. This object has gone out of range telescopes so new observations  runs will have wait until  2019 UN13 comes back in range(if ever).

If  the Earth was the size of a basketball  how far would the Moon [and the NEO Earth Close Approaches  be]? 

  Given the fact it was  the 2nd closest approache it is making buzz online ---by the way  it is too small to do anything.

In about 45 minutes from now (now = 10/31/19 7:00 am PDT), newly-discovered #asteroid C0PPEV1 will pass only 6200 km above Earth's surface. 45 minutes ago it was passing through Earth's shadow.
This is much closer than our geostationary satellites. https://t.co/q4qKuaUHjb pic.twitter.com/jsG2kaBY4O

From Bill Gray: C0PPEV1 = near-miss
this object is about to come _very_ close to us, perigee at 12520 +/- 70 km from the geocenter :https://t.co/5EoksMRcsg

People in Asia and Australia might be able to get
some astrometry on it over the next hour or two.

A near-Earth asteroid, identified as C0PPEV1, was spotted early Thursday by the Catalina Sky Survey, based in Arizona. It extremely close, 6,200 km above Africa at 15:45 UTC.https://t.co/Vrqjx6T3QX
