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.
For nearby stars, the parallax method gives the most accurate measure of distances.For nearby stars, the parallax method gives the most accurate measure of distances.For nearby stars, the parallax method gives the most accurate measure of distances.For nearby stars, the parallax method gives the most accurate measure of distances.
You can measure it by using absolute magnitude.
Astronomers measure it by predicting with the stars and using scientific tools
Measure the distance from Earth to nearby stars.
That is one of the things scientists use to help them measure a stars distance but it isn't just based on the color.
What must be known is the distance. And the most accurate method to measure the distance of nearby stars is the parallax - but this method won't work for stars that are far away.
Parallax
They use trigonometry to determine the distance to nearby stars. They measure the star's positions at one point in time, and again six months later, calibrating against the backdrop of the far distant stars. The nearby stars will show a parallax shift in position, so they calculate a triangle, with the Earth at two points, and the base 186 million miles long. The star is the third point on the triangle, and it is simple trigonometry from there to figure out the distance.
The surface temperature and the absolute magnitude, which is the brightness of the star when viewed from a standard distance of 10 parsecs.
parallax
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.
