Small cool star of low luminosity
WebbA star with four times the radiative power of the Sun has a luminosity of 4 L⊙. Luminosityis an absolute measure of radiated electromagnetic power(light), the radiant poweremitted by a light-emitting object over time. WebbOn the modern magnitude scale, Sirius, the star with the brightest apparent magnitude, has been assigned a magnitude of −1.5. Other objects in the sky can appear even brighter. Venus at its brightest is of magnitude −4.4, while the Sun has a magnitude of −26.8.
