Abstract
Recent observations of interstellar objects (ISO) crossing the solar system suggest the possible existence of ISO-generated craters on the Moon. We explore how different crater properties such as age, size, melt, and position can be used to search for ISO-generated craters on the lunar surface. We find that selecting young, small craters with a high volume of melt located away from the lunar poles increases the likelihood of association with a high-speed ISO by 100 fold as compared to selecting randomly, assuming high-speed ISO impacts generate melt. We note that craters from other sources however still massively outnumber ISO-generated craters.
