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

Today[2019-10-29] NASA-JPL released Episode 4 [Deflecting Disaster] of  Season Two of 'On a Mission' Podcast Targets Asteroids. "Unlike the dinosaurs, we have a space program. There are many ways we could steer an asteroid off its path towards Earth.? " This is the 4th of a 10-episode podcast host by Leslie Mullen. New episodes will be released weekly. For more information, see "Season Two of 'On a Mission' Podcast Targets Asteroids"[NASA JPL press release].

The 2019 UB8 2019-10-29 Flyby! How Close? Is Close?

Tonight(2019-Oct-28/29) the NEO 2019 UB8 (4.4 m - 9.7 m) will do a flyby(A.K.A NEO Earth Close Approaches) of a Nominal Distance of 0.50 LD (0.00127 AU) ~191,000 KM (~ 119,000 miles). Sorting by nominal distance, this close approach is listed in the top 270 of 22,500+ entries in JPL's close approach database. (As of 2019-Oct-28) Flybys within one LD are quite common from what we "know" NEOs flybys within one LD a few times every week or so.

If  the Earth was the size of a basketball  how far would the Moon be?

What is Close

Close is a relative term. "Close" to a major sports venue is not the same as "close" to the ER. If one were to think of a basketball-size Earth, it may in understanding what is "close" and what is "far." In this, basketball-size Earth system, the ISS would be at ~0.76 CM (0.3 inches); we had NEO Flybys at 10.35 CM (4.1 inches) [ 2011 CQ1 on 2011-Feb-04] before. The Moon would range from ~673.41 CM (~22.0 Ft) to ~753.81 CM (~24.7 Ft). 2019 UB8 will be ~347.62 CM (~11.4 Ft) from the basketball. To see 2019 UB8 tonight, check out the Virtual Telescope Project.
