A parallax is a change in apparent position, when YOU move. In astronomy, it usually refers to the change in the apparent position of a star, due to Earth's orbit around the Sun. It's there, whether you "use" it or not, but it is quite useful to determine distances of stars that are relatively close to us - since the farther a star is, the smaller will the parallax be. Even for the nearest star after the Sun, the parallax is smaller than one second (1/3600 of a degree).

A light-year is the distance light travels in a year - equivalent to almos 10 million million (or 1013) kilometers. In popular astronomy, distances to stars or galaxies are often stated in light-years; although astronomers often prefer another measure, the parsec, equivalent to about 3.26 light-years.A light-year is the distance light travels in a year - equivalent to almos 10 million million (or 1013) kilometers.

The distribution of metals (In astronomy, that is any element other that hydrogen and helium) is reliant of the population stars. (See related question) Metal rich stars, population I stars, are the latest "breed" of stars, whereas population III stars are the oldest and are classed as metal free stars. So the furthest galaxies are likely to be formed from the initial gases from the big bang and will be metal free stars,
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 most accurate way to determine the distance to a nearby star is through parallax measurement. This method involves observing the star's apparent shift in position against background stars as the Earth orbits the Sun. By measuring this shift, astronomers can calculate the star's distance based on trigonometry.
Astronomers use the method of parallax to determine the distance to relatively close stars like Sirius. By measuring the apparent shift in position of the star as the Earth moves around the Sun, astronomers can calculate the star's distance based on trigonometry.
The distance to nearby stars can be measured using the parallax effect. Astronomers observe the apparent shift in position of a star against the background of more distant stars as the Earth orbits the Sun, allowing them to calculate the star's distance based on the angle of the shift.
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.
You can measure it by using absolute magnitude.

Distance to nearby stars can be determined using the method of trigonometric parallax, which involves measuring the apparent shift in position of a star relative to more distant stars as the Earth orbits the Sun. This shift allows astronomers to calculate the distance to the star based on the angle subtended by the Earth's orbit.
That is one of the things scientists use to help them measure a stars distance but it isn't just based on the color.
