A "standard candle" in astronomy is an object whose luminosity (its true
brightness, not just how bright it seems to us) can be estimated,
based on characteristics of that type of object. Then its distance can be
estimated from its "apparent magnitude".
The stars called "Cepheid variables" are a good example. The rate at which
their brightness varies is closely linked to their luminosity.

∙ 11y agoA "standard candle" is any object - such specific types of stars, star clusters, or galaxies - whose real brightness is known, and can thus be used for distance calculations by comparing its real brightness with its apparent brightness (the farther it is away from us, the less bright it looks).
