How big?
KA1J says the ball is Ø4.77mm/Ø0.185" which implies he measured the thing with a metric caliper but rounded out too much because 4.77 x 25.4 = 0.1878 which in turn says it's most likely a Ø3/16" ball.
Mind you, that's either a horkin' great key in the photo or a different ball. Admittedly my size estimation powers have faded since I started to wear bi-focals but the ball next to the key looks to be Ø1/8" or smaller.
And while I doubt it fell out of a rear wheel bearing I do hope KA1J discovers where it did come from so he can sleep at nights again.
