and 
which are separated by a distance <em>d</em> will be given by the formula:
So in our case, we have 
The technique which is the most useful for measuring the distance to a galaxy located 10 million light-years away is Cepheids
A Cepheid variable is a particular kind of star that pulses radially, varying in diameter and temperature while causing changes in brightness with a clearly discernible steady time and amplitude.
A light-year is defined as the total amount of distance covered by light in a year. It is usually a unit to measure very large distances which usually concerns the Outerspace
A galaxy is a system made up of stars, stellar debris, interstellar gas, dust, and other matter that is gravitationally bound. The name "galaxy" is derived from the Greek word "galaxies," which is an allusion to the Milky Way and literally means "milky."
