The distance of closest approach of two objects is **the distance between their centers when they are externally tangent**. The objects may be geometric shapes or physical particles with well-defined boundaries. The distance of closest approach is sometimes referred to as the contact distance.

The distance of the closest approach is given by, `**d =(2Zze^(2))/(4pi epsilon_(0)k)`** where k is kinetic energy of `alpha`-particle.
