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
50,000 light years (thats long)
SIXTYTHREE FT. (63ft.)are in 21 yards.
8.7 light-years is 51,144,039,300,000 miles.
Assuming that "hundth" means a hundredth, the answer is 1.63
The Milky Way's diameter is about 100,000 light-years.
Traveling 39 light years would take 39 years at the speed of light.
Traveling 40 light years would take 40 years at the speed of light.
light years
14 Billion 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.
