What is the angular size (in arc seconds) of Phobos observed from Earth when Mars and Appendix tables. For the size of Phobos, use the maximum dimension given in the text. Assume that the orbits of Earth axes.) angular diameter (in arc seconds) linear diameter 2.06 x 10 distance X erc seconds Compare that with the resolution limit of about 1 arc second for ground-based telescopes. O This is much less than 1 arc second, so Phobos cannot be resolved from Earth using ground-based telescopes, O This is much less than 1 arc second, so Phobos can be resolved from Earth using ground-based telescopes. O This is much greater than 1 arc second, so Phobos cannot be resolved from Earth using ground-based telescopes This is much greater than 1 arc second, so Phobos can be resolved from Earth using ground-based telescopes.
