Is aerospace engineering too niche for a college major?

I???m interested in aerospace engineering, but I???m scared to go straight into it because it is a niche subject. Would going into mechanical or electrical first be better? If so, which one?

I am a high school student passionate about mathematics and physics! I???ve always loved space but I want to keep my options open. I???m having a hard time deciding which path to take as I start applying to post secondary schools. I???m a good academic student, however I???m afraid I wouldn???t be able to compete in the aerospace industry with so many other bright applicants and minds. Any advice is appreciated! :)
