1 AU is the distance from the center of the earth to the center of the sun 1AU = 1.496 * 10^11 meters 1 Parsec = 1 pc = 3.086 * 10^16 meters and 1 light year is = to 9.46 x 10^15 meters

3. anonymous

So 1 AU is = to 4.84814 * 10^-6 Parsecs

4. anonymous

What equations do I make to get those answers?

5. anonymous

I don't quite understand...

6. anonymous

To convert parsecs to light years its ly = pc * 3.2616 to convert ly to parsec it's gonna be $\frac{ ly }{ 3.2616 } = parsec$ and Au to ly its 63239.7263 * ly = au so for example if you have 147 light years and want it in AU it would be 147* 63239.7239 = 9 296 239.7661 AU and you can convert it to sig figs

7. anonymous

Oh, where do you get the 3.2616 and the 63239.7 from the question?

8. anonymous

1 light year over 3.2616 you'll get 0.307 (rounded) which is in your table "for one light year equals"

9. anonymous

Ohh, ok thank you!

10. anonymous

do you understand? I'm not sure if I explained it clearly or not hehe.

11. anonymous

This one was hard lol

12. anonymous

I think I made it harder than it should have been...
