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.

Explanation:

Phobos minimum distance might be about 0.524 - 0.0000627 = 0.524 AU, rounded to 3 decimals.. Maximum is 2.524 + 0.0000627 = 2.524 AU, rounded to 3 decimals.
