Venus orbits 0.72 AU from the sun. What is that distance in kilometers?

Answer 1

If you don't know what an AU is, you can Google it. Then multiply.

Answer 2

1 AU is about 93 million miles (92,955,808 miles to be exact)
100km is 62.14 miles
This should help a little.

Answer 3

One AU is the Earth's average distance from the sun, which is

149,598,000 kilometers

Multiply that by 0.72
