Final answer:
The distance to Mars is about 125 times greater than the distance to the Moon. The distances are 400,000 km to the Moon and 50,000,000 km to Mars. As an analogy, if Earth were a grain of sand, Mars could be 15 to 100 feet away.
Step-by-step explanation:
The distance from Earth to the Moon is about 4 times 105 kilometers (400,000 km), while the distance from Earth to Mars is estimated at 5 times 107 kilometers (50,000,000 km). To complete the sentence: The distance from Earth to Mars is about 125 times greater than the distance from Earth to the Moon. This comparison can be calculated by dividing the distance to Mars by the distance to the Moon (50,000,000 km รท 400,000 km = 125).
To visualize these astronomical distances, it helps to use analogies. If Earth were the size of a grain of sand, the Moon would be a speck, and their separation would span the distance about as wide as the separation of your eyes. In this analogy, Mars would be a variable distance away, anywhere from 15 to 100 feet. Illustrating these distances shows just how vast the space between celestial bodies can be compared to terrestrial scales.
