15 light years = 8.81774972 × 1013 miles
The distance light will travel in 15 years. Or about 1.42 x 1014 kilometers.
Because you might have seen it in a telescope years ago idkAnother AnswerA light year is a measure of distance. If an object is 15 million light years away, the light you are looking at in this moment was produced 15 million years ago. If a star that far away went supernova at this moment, we wouldn't know it for another 15 million years.The light we see on the surface of our planet from the Sun is a little over 8 minutes old, because it took that light about 8 minutes to travel from the Sun to Earth.
Light year, the Distance travelled by light in a year. .. The general unit for distance is meters... so light travels at 300 000 000 m/s. 60 seconds in 1 minute. 60 minutes in 1 hour. 24 hours in 1 day. 365 days in a year. So 300000000 x 60 x 60 x 24 x 365 = 9.46x10^15 m.
The SI unit of length is the meter. Multiply the number of light-years by 9.5 x 1015.
Light years and parsecs. A light year is approximately 9,470,000,000,000,000 meters (9.47x10^15) and a parsec is roughly 3.26 light years

15 million in standard form is 1.5 × 107
15 hundreds (1,500) in standard form is 1.5 × 103
15 and 1 tenth is standard form is 1.51 × 101
15/15 = 1
15 cubed (or 153) in standard form is 15 x 15 x 15 which equates to 3,375.
15 light years = 1.42x10^14km
It is: 3,375
