Procyon is not hotter than Rigel. Procyon, a main-sequence star, has an effective temperature of about 6,500 Kelvin, whereas Rigel, a blue supergiant, has an effective temperature of approximately 11,000 Kelvin. This makes Rigel significantly hotter than Procyon. Additionally, Rigel's higher temperature contributes to its blue color, while Procyon has a yellowish hue.
