The satellite, which has a diameter of only 25 km, orbits very close to Mars, about 9 thousand km away. In terms of your comparison; The distance of the moon to the Earth is around 380 thousand km on average.
If the satellite were Moon's distance from Mars, it would hardly be spotted as a very faint spot in the sky. The first reason for this is that the satellite is very small, and the second reason is that it reflects the sunlight very badly due to its very low albedo. However, since it is close to the planet, it can be seen in Mars skies even during the day.

This little satellite, named after Phobos (Fear), the child of Ares, the god of war in Greek mythology, is like his brother Deimos (Terror); Mars is known to be a gravitational meteor. This unfortunate satellite, which gets closer to the surface every day (2 meters every 100 years) due to the tides, is estimated to be destroyed by the strong gravity of the planet and fall to the surface of Mars within 50 million years.
