How do you measure the distance to a cepheid?
Cepheids have a certain relationship between their period, and their absolute luminosity. Thus, their absolute luminosity can be determined. Comparing this with their apparent luminosity allows us to calculate their distance.Cepheids have a certain relationship between their period, and their absolute luminosity.

Why is the suns luminosity 1?
A solar luminosity is equal to the current luminosity of the Sun, which is 3.839 × 1026 W, or 3.839 × 1033 erg/s.So dividing one solar luminosity with the Suns luminosity gives 1.Also it is a lot easier talking about a luminosity of 1 rather than 3.838 x 1026 W, the same way astronomers use 1 AU to mean 150,000,000km.
How do astronomers use luminosity?
Astronomers use luminosity to measure the total amount of energy a star emits in all directions. By knowing a star's luminosity, astronomers can calculate its distance, size, and temperature. Luminosity helps astronomers understand the life cycle of stars and their evolution.
How does the luminosity of a blackbody vary with its surface temperature?
Both the absorption and the luminosity of a blackbody in equilibrium increase in magnitude with increasing temperature, and the spectral distribution of the luminosity increases in frequency (decreases in wavelength).
