2020 CD3: Characters & Art

2020 CD3, or CD3 for short, is a tiny near-Earth asteroid (or minimoon) that ordinarily orbits the Sun and makes close approaches to the Earth–Moon system, in which it can temporarily enter Earth orbit through temporary satellite capture (TSC). It was discovered at the Mount Lemmon Observatory by astronomers Theodore Pruyne and Kacper Wierzchoś on 15…
