How long will Procyon last?
10 to 100 million years
Procyon A is bright for its spectral class, suggesting that it is a subgiant that has nearly fused its core hydrogen into helium. It will eventually expand as “burning” moves outside the core and the star swells 80 to 150 times its current diameter. This should happen within 10 to 100 million years.
