The answer should be A. A controlled nuclear chain reaction produces heat, driving steam turbines to produce energy.
The distance of Earth from the Sun is 94.5 million miles.
A light year is 6 trillion miles so it would be less.*
1 AU means 1 astronomical unit or the aproximate distance from the earth to the sun
1AU=<span>149597870.7 kiometers
1 billion=1,000,000,000
600 billion=600,000,000,000
</span>
<span>x times 1AU=600,000,000,000
x times </span>149597870.7=<span>600,000,000,000
solve for x
divide both sides by </span><span>149597870.7
</span>x=4010.75
so aprox 4011 AU's
