Light year or astronomical units
Answer #1:no=================Answer #2:Yes.Another answer: The primary use of triangulation may not be to measure the distance of stars, but the method which is used to measure the distance of close stars is primarily triangulation.
light years
The appliance of science
. . they are a convenient unit. Another convenient unit is the parsec.
light years
it is so far that kilometers wont work
Meters can be used; however, in practice, such distance are usually measured in parsecs, or (in popular astronomical literature) in light-years.
Light years, parsecs, and kiloparsecs. Light years and parsecs are used to measure distances between neighbouring star system's, kiloparsecs are used to measure distances within a galaxy.
Angstroms
Kilometres or miles are used to measure distances between cities.
The unit of measurement typically used to measure the distance between buildings is feet or meters.
If I remember all of my astronomy classes correctly, the unit of measurement between Earth and the Sun is 1 A.U., or Astronomical Unit, which is equal to 93 million miles. 1 light year is equal to 5,865,696,000,000 miles (9,460,800,000,000 km). Astronimical Units are used to measure distance within our own galaxy. To measure the distance between stars and galaxies, the unit is called a parsec (PC). 1 PC = 3.26 light years. Hope this helps!
