Question

A light-year is defined as the distance traveled by light in a vacuum during one tropical year. How many light-years are in a parsec?

Answer 1

Answer #1

One parsec is the distance at which one astronomical unit subtends an angle of one arcsecond

1 parsec = 3.26 light years.

f) in vacuum, light travels at about 186,282 miles per second. One mile is about 161 kilometers (km). Astronomers prefer to use units of distance that are reasonable in describing how far objects are from Earth. For example, for distances in the solar system we use the astronomical unit (AU), which is equal to the average distance of Earth from the Sun; 1 AU is about 150 million km. For distances to stars and galaxies, astronomers use the light-year (1...
