In the field of astrophysics, the study of neutron stars is often conducted to improve nuclear models. This work evaluates the composition of the outer crust of a cold non-accreting neutron star. The standard approach to the outer crust is considered: nuclei are fixed in a Coulomb lattice surrounded by a Fermi gas of free and degenerate electrons. It is shown that considering electrons as ultra-relativistic is a reasonably accurate approach for our purposes (99.98%). The nuclear composition of the lattice is studied by minimizing the Gibbs energy per baryon using a custom Python program. Additionally, the effect of the variations of the Liquid Drop Mass formula parameters on the crust composition is explored by: 1) calibrating the parameters to different
experimental masses; and 2) systematically changing the asymmetry parameter
