Light years or Parsecs
Stars are not measured in light years. The distance between them is.
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.
usually the space is measured in light years
Light Years.
The answer will depend on where the distance to the polygon is being measured from.
in light years
That is one of the things scientists use to help them measure a stars distance but it isn't just based on the color.
The distance to stars is typically measured in light-years, which is the distance light travels in one year. Light-years are used because the distances to stars are vast and measuring in kilometers or miles would be impractical. For closer stars, distances can sometimes be measured in parsecs, which is another unit of distance based on trigonometric parallax.
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.
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.
The Orion constellation is approximately 1,344 light-years away from Earth. This distance can vary slightly depending on the specific stars or objects within Orion that are being 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.
