What is the distance between Mars's moon, Phobos, and the earth?

Answer 1

Mars-Earth distance varies from 0..524 AU to 2.524 AU, using average distances from the Sun. Phobos mean distance from Mars is 9376 km = 6.27 E-05 AU, nearly - negligible against Mars distance.

The maximum distance to Phobos is 2.524 + 0.0000627 = 2.524 AU, rounded to three decimals, while the minimum distance may be roughly 0.524 - 0.0000627 = 0.524 AU.

The average distance between Mars's moon Phobos and Earth is approximately 77.8 million kilometers (48.3 million miles). However, this distance can vary due to the elliptical orbits of both Earth and Mars around the Sun, ranging from around 54.6 million kilometers (33.9 million miles) at their closest approach to about 401 million kilometers (249 million miles) at their farthest distance.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
