Ceres is a dwarf planet composed mainly of ice and rock with evidence of melting water, which is important because liquid water is a key ingredient for habitability. Many of the signs of water on Ceres are linked to craters, where projectiles impacted the surface, delivering enough kinetic energy to melt the surface. In this study, we focused on estimating the diameter and velocity of projectiles that could have impacted Ceres. We implemented analytic impact scaling laws into Python with the dwarf planet's gravity, density, and other physical parameters to generate a lookup table of possible transient crater sizes and matched them with corresponding impact velocities and projectile diameters. The results can provide insight into past projectiles that have impacted the surface of Ceres and the extent to which it underwent melting. In addition, this can be used for planning future space exploration.
