document.write( "Question 971718: The speed of light, often denoted by the variable c, is 2.998x10^8 meters per second. Because the distance light travels in one year is so large, in 1838 the German astronomer Bessel coined the term \"light year\" to represent this distance. Bessel first used this term when he announced that the distance to the star 61 Cygni was 10.3 light years. \r

You can put this solution on YOUR website!
1 light year= distance travelled by light in 1 year
\n" ); document.write( "So, distance to Cygni is 10.3 light years
\n" ); document.write( "= 10.3 * light's speed * no. of seconds in a year
\n" ); document.write( "=\"10.3%2A%282.998x10%5E8%29%2A%28365.24%2A24%2A3600%29\"\r
\n" ); document.write( "\n" ); document.write( "So, yes, you are right. Go ahead.
