61 Cygni
61 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.

How is the distance measured of stars less than 1000 light years away?
The parallax method is usually used in this case. Earth's movement in its orbit cause an apparent shift in position in such a star.
What compares the brightness of stars as if they were the same distance from earth?
midorz
What is the units used to measure the distance of stars to the earth?
light years
The brightness of stars as they appear from Earth is measured by magnitude?
Stars are measured in brilliance called magnitude. The faintest stars visible to the naked eye are mag.6. Brighter ones are mag. 1 or 2, the even brighter stars have negative magnitude. So its like a number line in math: Brighter Fainter -6_-5_-4_-3_-2_-1__0__1_2_3_4_5_6
Is it true that two stars that have the same brightness are the same distance from earth?
false
Is the distance between stars and earth measured in kilometres or light-years?
Light Years.
In distance in space between stars and earth measured in kilometres or light years?
in light years
Are the stars measured in light years?
Stars are not measured in light years. The distance between them is.
The distance to nearby stars can be measured by using?
Parallax
If a star's parallax angle is too small to measure what can you conclude about the stars distance from earth?
You can conclude that it is farther than a certain distance. How much this distance is depends, of course, on how accurately the parallax angle can be measured.
How is the distance of stars in being measured?
Light years or Parsecs
What is the Distance between the Leo stars?
The stars in Leo the Lion (and all the other constellations) are not next to each other. They are all very different distances from Earth and therefor can't be measured in those terms.
What is the stars in bootes distance from earth?
Each star has a different distance.
What is it called when you measure distance between stars?
usually the space is measured in light years
Do all-stars have measurable parallax angles?
No, only the closer ones have a parallax that is large enough to be measured. The first star to have its parallax measured was 61 Cygni, measured by Bessel in 1838 and found to be at a distance of 10.3 light years, later corrected to 11.4. The closest star Proxima Centauri has a parallax of only about 0.7 seconds of arc. Before then the absence of parallax for the stars was considered an important part of the case that the Earth cannot be revolving round the Sun.
Stars appear as small points of light in the sky because?
Mainly because of the rotation of the Earth.
How many miles does Rigel is away from Earth?
Distances between stars are not measured in miles: that is like measuring the distance from the Earth to the Sun in thousandths of an inch! However, since you asked, Rigel is approx 5 quadrillion miles away.
