It is usually calculated through the parallax. The apparent position of the star, against the background of stars much further away, is observed at two opposite points in the earth's orbit around the sun. The apparent angular shift is recorded. Then, knowing the distance between the two positions of the earth, and a bit of trigonometry, the distance to the star can be calculated. An apparent displacement of 1/3600 degree (or 1 second) is called a parsec, and is equal to 3.086*10^13 kilometres

Light year distance to the stars?
The closest star is the Sun - about 8 light-minutes away. The closest star after that is at a distance of 4.3 light-years; the farthest observable galaxies (galaxies are made up of stars) are at a distance of over 40 billion light-years.The closest star is the Sun - about 8 light-minutes away.

Are other stars the same as the sun?
One of the closest - in type and distance - is Alpha Centauri A
What stars are closest to us?
The closest star is the Sun. The distance is a little over 8 light-minutes. That is, it takes light from the Sun that long to reach us.The next-closest star is Proxima Centauri. The distance is about 4.2 light-years.
What is the stars in bootes distance from earth?
The stars in the constellation Boötes are at varying distances from Earth, with the closest star being around 37 light-years away and the farthest stars in the constellation being thousands of light-years distant.
Which of these stars is closest to the earth Polaris Antares or Betelgeuse?
Polaris is the closest of the three stars.
What is the distance in light years of Cenaturus constellation from earth?
A constellation is basically a general direction in space. It doesn't have a definite distance. Different stars in a constellation are at different distances. The closest star from Earth happens to be in the Centaurus constellation, at a distance of about 4.2 light-years. But please note that other stars in the same constellation are much, much farther from us.A constellation is basically a general direction in space. It doesn't have a definite distance.

What stars are near in the earth?
The Sun is the closest star. Next closest are the three stars of the Alpha Centauri system, of which the closest is Proxima Centauri.
What is the closest system to your sun?
The closest star system to our Sun is Alpha Centauri, which consists of three stars: Alpha Centauri A, Alpha Centauri B, and Proxima Centauri. Proxima Centauri is the closest to the Sun at a distance of about 4.24 light-years.
How does the distance of planets from Earth compare to the distance to the stars?
Planets are tremendously closer than the stars are. Even the closest star (other than the sun, which is also a star) is tens of thousands of times farther away than the most distant planet in our solar system.
Why do the closest stars appear to move across and back against the more distant stars?
That's the result of Earth moving around the Sun, in its orbit. The distance Earth moves (a total of about 300 million kilometers) is rather puny compared to the distance to the stars, so the corresponding apparent movement (known as "parallax") of even the closest star will be less than one arc-second, i.e., less than 1/3600 of a degree.
Why are Light Years used to measure distance of stars from the Earth?
Because no other unit of distance is large enough. The closest star system to us is 4.2 light years away, which is about 25,000,000,000,000 miles.
Which is the closest distance of the earth from the sun?
it is about 92 million miles from the earth to the sun at its closest distance.
