A light year is 9.4607 x 1012 kilometres, so 63 times that would be almost 600 x 1012 kilometres
1012 = 1,000,000,000,000
1,3,7,9,21,63 Answer: 6
SIXTYTHREE FT. (63ft.)are in 21 yards.
50,000 light years (thats long)
Assuming that "hundth" means a hundredth, the answer is 1.63
8.7 light-years is 51,144,039,300,000 miles.
The Milky Way's diameter is about 100,000 light-years.
14 Billion years
light years
5 years in light years
That means that M31 (the Andromeda Galaxy) is at a distance of about 2.5 million light-years, and that it takes the light 2.5 million years to get here. Light moves quickly, but not instantaneously.
It's exactly 7 light years away.One light year is the distance that light travels through space in one year.7 of those is a distance of something like 41,150,289,900,000 miles.
4.25 years, because it is 4.25 light years away.
