Answer 1

To find the difference between the distances from Earth to Mars and Earth to Neptune, we subtract the distance from Earth to Mars from the distance from Earth to Neptune.

4.3514×10^9 km - 2.25×10^8 km = 4.3514×10^9 km - 0.225×10^9 km = 4.1264×10^9 km

Therefore, Neptune is 4.1264×10^9 km farther from Earth than Mars.
