Phobos, one of Mars' moons, is significantly smaller than Earth. Phobos has a diameter of about 22.4 kilometers, while Earth's diameter is approximately 12,742 kilometers. This means that Phobos is roughly 570 times smaller than Earth in terms of diameter.

What is the atmospheric air pressure of Phobos?

it is either zero or very, VERY near zero. A zero air pressure implies there is no atmosphere. Phobos is merely a captured asteroid, these objects are too small, not enough mass, to be capable of a large enough gravitational field to maintain an atmosphere.

How far away is Phobos from Earth?

Phobos, one of the moons of Mars, has an average distance of about 9,378 kilometers (5,827 miles) from the center of Mars. Since Earth is, on average, about 225 million kilometers (140 million miles) away from Mars, we can estimate that Phobos is approximately 225 million kilometers plus 9,378 kilometers away from Earth. This puts Phobos at a distance of roughly 225,009,378 kilometers (140,009,378 miles) from Earth.
