usually the space is measured in light years
light years
Light Years.
Light year or astronomical units
you use light years, and other units
Astronomers use the unit of measure "Light Years" to calculate the distance between pretty much anything in the Universe.
Astronomers use a method called parallax to measure the distance to nearby stars. Astronomers can measure parallax by measuring the position of a nearby star with respect to the distant stars behind it. Then, they measure the same stars again six months later when the Earth is on the opposite side of its orbit.
Answer #1:no=================Answer #2:Yes.Another answer: The primary use of triangulation may not be to measure the distance of stars, but the method which is used to measure the distance of close stars is primarily triangulation.
To measure the distance of stars you have to measure by light years.
light year the DISTANCE light travels in a year so 'light year' is not a measure of time.
light years
the time between eclipses and the average distance between the stars
