[bkgfixxf] Great Conjunction in radians

the angular separation between Jupiter and Saturn at closest approach in 2020 was 0.001776 radians.

1/(2*tan(angle/2)) = 563.06

small angle approximation: 1/angle = 563.06

(small angle approximation is why radians are nice.)

object of linear size x, at distance 563*x.

if you missed it, perhaps easy to simulate with two point light sources, perhaps car headlights.  is it easy to simulate the brightnesses?  the Conjunction took place during twilight; there was still light in the sky.

or separation between fingers with outstretched arm (depends on how long your arm is).
