That's still excessive by any reasonable standards. Names should be
descriptive, but no more verbose than necessary. How about:

force_N = -G * mass1_kg * mass2_kg / distance_m ** 2

I'm fine with "G" as is because it's the standard name for the value
in physics contexts, and it's presumably defined in the code as a
constant. It's every bit as clear as "pi".
