is 1 astronomical unit = the distance of the earth form the sun? I seem to remember this from way back
OpenStudy (welshfella):
but i might be completely wrong ..
OpenStudy (elonasushchik):
so im understanding that my answer was wrong
OpenStudy (elonasushchik):
1 astronomical unit 1 AU = 1.4960 * 10^11 meters
it is the average distance between earth and sun
mercury to sun distance is = 46,000,000 * 1000 meters
= 4.6 * 10^9 meters = 4.6 * 10^9 / 1.4960 * 10^11 AU
= 3.0.74 / 100 = 0.0374 AU
OpenStudy (welshfella):
if thats the case the its 46 / 149.8 am
