Let us say that at their **closest approach**, Mars is about **54.6 million kilometers** from the Earth. Mars has a diameter of about **6,779 km**. On the same evening let's say our Moon is about **384,400 km** away and has diameter of about **3,478 km**
**If we suddenly swapped the position of the Moon and Mars, roughly how many times larger would Mars appear relative to the Moon? **
(round to one decimal place)
Here is a picture *before the swap occurs:*
