The Stefan-Boltzmann law estimates the total amount of emission, per unit area, leaving the surface of a blackbody. This is termed the total emittance. The Stefan-Boltzman law is described by the formula Eq (1): E=SB - T4 Eq (1) Where E is the total emittance in W/m2,SB is the Stefan-Boltzmann constant with a value of 5.67108W/m2K4 and T is the blackbody temperature in K. The nearby sunlike star Tau Ceti has a surface temperature of approximately 5344K. What is the total emittance from Tau Ceti
