None. A light year is a measure of distance, not of time.
3.262 light years.
...one?
1,000,000,000 light-years (one billion light-years) are in one Gly
Years are a measurement of time; light years are a measurement of distance. A light year is the distance light travels in one year (in a vacuum).
"How many light years does Dschubba have?" "How many light years does Dschubba have?"
One meter is about 0.000,000,000,000,000,105,7 light-years.Calculation: As a light-year is 9,460,730,472,580,800 meters, one meter equals 1/9,460,528,400,000,000 light-years = 1.057,000,834,024,615,4 × 10-16 light-years - or about 105.7 atto-light-years.
9,460,730,472,581 kilometers in one light year.
one billion light years = 5.87849981 × 1021 miles
2,100 light years = 6.51808059 × 1019 feet
Much less than one light year. 5 billion miles is "only" about 0.000850557142 light years.
One parsec is equivalent to 3.3 light years. 150 parsecs = 150 x 3.3 = 495 light years
Callisto, one of Jupiter's moons, is about 481 million miles away from the sun. In terms of light-years, it is roughly 0.000005 light-years from the sun.
