Phobos is one of the moons of Mars. Mars averages 1.52 AU from the Sun, while the Earth averages 1 AU from the Sun.
So at conjunction (when Mars is closest to Earth), Mars is about .5 AU away, and at opposition (Mars on the other side of the Sun from us) Mars is about 2.5 AU away.
This is an over-simplification; Mars' orbit is more eccentric than Earth's, by about 9%. Sometimes Mars is a little closer than .52 AU at conjunction, and sometimes it is a little further away. But not by much.

A year on Phobos, which is the closest moon to Mars, is approximately 7 hours and 39 minutes. This short duration is because Phobos orbits Mars at a close distance and at a rapid pace compared to Earth's moon.
If you define a 'year' as the time required for a solar-system object to complete one revolution around the sun, then Phobos' year is identical to Mars' year, since Phobos is gravitationally bound to Mars. That period is 687 earth days.
Phobos is one of the two moons of Mars. It isn't very big. Using the Hohmann Ellipse Transfer Data, it should take around six months for a one way trip from Earth to Mars. You depart earth at such time as Mars conveniently swings by to encounter your outbound ship. You may have to wait a few years for such favorable conditions, or you could play tricks with gravity assists, building up speed by passing close to the moon, etc. The orbital transfer described above uses minimal fuel.
On the other hand, with big engines and laser canon, you could simply boost hard towards Mars, and impact the surface of Phobos without slowing at all. It would get you there in a hurry, but you would end up as an ionized plasma upon arrival. You could reduce your trip time to just a few weeks if you had enough fuel.
Mars has two moons: Phobos and Deimos. Both moons are irregularly shaped and are thought to be captured asteroids from the asteroid belt.
The name Phobos means "fear" or "panic" in Greek. In Greek mythology, Phobos was the god of fear and a companion to Ares, the god of war. Phobos is also the name of one of the moons of Mars.
No, Phobos is larger than Deimos. Phobos has a larger diameter of about 22.4 kilometers, while Deimos has a diameter of about 12.4 kilometers.
Prince Phobos was created in 2001.
The moon of Mars is called Phobos.
