what you do is set up a conversion factor problem and then solve.its easy!
it is kind of obvious that 1 light year is 9,460,730,472,580 km so 4.3 times
9,460,730,472,580 that's 40781141032094 km also the alpha centauri
system is 4.3 light years away
Answer: 4.3 ly = 40,653,296,308,598.4 km
4.2 light year = 3.97342193 × 1013 kilometers
4.22 light years is about 39.95 trillion kilometers.
1 light-year is 9,460,700,000,000 kilometers.
Incredibly far. 640 light years equates to 3.76223988 × 1015 miles.
125 light years!!!!! Remember light years is the meausre of how far light travels in one year.
167 light years
The distance to the moon is about 1.3 light seconds or about 0.000000032 light years.
The Pleadies star cluster is about 400 light years from Earth.
As far as light can travel
Incredibly far. 640 light years equates to 3.76223988 × 1015 miles.
125 light years!!!!! Remember light years is the meausre of how far light travels in one year.
167 light years
Algieba is about 90 light years away from us
I think 2 light years. (1 light year=9.5 trillion km.)
The distance to the moon is about 1.3 light seconds or about 0.000000032 light years.
Not light years, 107 milllion km.
Two light years is a distance of about 11.72 trillion miles.
The Pleadies star cluster is about 400 light years from Earth.
Approximately 4.2 light-years.
260 light-years
