The distance between planets varies as they move in their orbits. The minimum distance from the Earth to Mars is about 0.35 AU.

Alina [70]

Answer:

52,360,000km

Explanation:

To solve this problem you use a conversion factor.

By taking into account that 1UA = 1.496*10^{8}km you obtain:

$0.35UA*\frac{1.496*10^{8}km}{1UA}=52,360,000km$

hence, 0.35UA is about 52,360,000km. This is the least distance between Mars and Earth
