Approaching minimums is called out by an on board computer when the plane is on approach to land. It means that the pilots are approaching the minimum altitude that they can safely fly to without the runway in sight (ie, through clouds and rain etc). If they reach that minimum altitude and the runway is still not in sight the pilots must call off the landing "go around" and attempt the landing again.
The minimum distance of Jupiter from Earth (i.e. the closest approach) is equal to about 588.5x10^6 km.
Using average distances from the Sun the minimum distance is 1.0 - 0.7233 astronomical units, 0.2767 AU or 41.39 million km.But using the eccentricity of the orbits as well, the Earth's distance is 1.0±0.01672 AU, while Venus's distance is 0.7233x(1±0.00679) AU.Therefore the Earth's minimum distance is 0.9833 AU and Venus's maximum distance is 0.7282 AU. The difference is 0.2551 AU so the minimum distance from the Earth to Venus is 38.16 million km.
