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.
A stellar unit refers to a unit of distance used in astronomy to measure the distance between stars. It is typically equivalent to the mean distance between stars within a galaxy, which can vary depending on the galaxy being observed.
Astronomers use a method called parallax to measure the distance to nearby stars. By observing how a star's position changes when viewed from different points in Earth's orbit around the Sun, astronomers can calculate the star's distance based on the angle of this apparent shift.
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
Astronomers use parallax to measure the distance to other stars by observing how a star appears to shift its position against the background of more distant stars as the Earth orbits the Sun. By measuring this apparent shift, astronomers can calculate the distance to the star based on the angle of the shift and the known distance between the Earth and the Sun.
