Verona, a public place:

Romeo is standing 1 meter from Juliet at
a time when Venus happens to be about
41*10^9 meter from Earth.

Assume spherical bodies with masses
Romeo: 60 kg
Juliet: 50 kg
Venus: 4.87*10^24 kg

Estimate the gravitational forces of Juliet
and Venus on Romeo ...

.... and you will find that Venus attracts
Romeo a lot more than Juliet does.
