Candela (cd) is the unit of luminous intensity of a light source in a specific direction. It is also called candle.
distance
light years
One Light-year is 63,024 Astronomical units.
To measure the distance of stars you have to measure by light years.
The unit that measures the greatest distance is a light-year, which represents the distance that light travels in one year. This unit is frequently used in astronomy to measure vast distances between celestial objects.
The most commonly used unit to measure distances beyond our solar system is the light-year. This unit is the distance that light travels in one year in a vacuum, equivalent to about 9.46 trillion kilometers.
A candela is a unit of measurement for light sources and light emissions. Light beams projects different color at different wavelengths, and a candela is used to measure the intensity of the light.

You cannot 'measure' light. However, there is the light-year, a measurement of the distance light can travel in one year. there are many. Lumens, cadlepower, foot candles and candelas. There are probably a few more.
Light years: the distance that light travels in a year.
