They are called Coronovirus because under
TEM (transmission electron microscopy) the virus has club shaped spikes
all around the virus that make it look like an image of the solar corona (AKA the SUN). These spikes (peplomeres) are used to help penetrate the targeted cell (especially cells in the lungs) by the virus. Once inside, the virus uses the cells RNA to replicate itself and infect other cells. Coronovirus
