depends who's measuring and which star. it is a matter of preference.
1. kilometers/miles - relatively nearby star like our sun
2. lightyears - near-medium star like the nearest star except the sun
3. parsecs - medium-far star
4. megaparsecs - very far star
there are some others but they are not the usual ones
Star brightness is defined in terms of apparent magnitude, which is how bright the star appears from Earth. Star brightness is also defined by absolute magnitude, which is how bright a star appears at the standard distance of 36.2 light years. Luminosity is also a way that a star's light is measured.

Interplanetary distances are measured in either kilometers or in miles. For the distant planets, some measures are measured in Astronomical Units, where one AU is the distance between the Sun and the Earth. So, 1 AU = 93,000,000 miles.

According to me, there are many units of distance given by S.I units .The longest unit of distance is light years and after that it is miles.
That's the star's "azimuth".

The distance to a star.
The distance of a star on the horizon, measured in degrees, is called its azimuth. Azimuth is the angle measured clockwise from true north to the star's position in the sky. It can range from 0° (north) to 360° (back to north).
No, the color of a star does not directly indicate its absolute distance. Star color is related to its surface temperature, and stars of different temperatures can be located at varying distances from Earth. The brightness of a star, as measured by its apparent magnitude, is more indicative of its distance.
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.
It's measured in light-years (or parsecs) which is trillions of miles.

Declination, which is measured as an angle, north is positive and south is negative. The declination of a star etc. is also the latitude at which the star passes overhead.
61 Cygni61 Cygni first attracted the attention of astronomers because of its large proper motion. In 1838, Friedrich Wilhelm Bessel measured its distance from Earth at about 10.4 light years, very close to the actual value of about 11.4 light years.
