The Hubble Space Telescope was able to take a clear picture of the
little moon of Mars and Phobos during its orbital journey around Mars,
and because the planet was small and faint, it appeared like stars on
Mars.In just 22 minutes the Hubble telescope picked up 13 separate images of the Phobos moon,
The
images allowed astronomers to produce a video of the lunar movement
that appeared dimly, although the aim behind the imagery was Mars
itself, but the shooting of the moon Phobos was a coincidence as a
reward for astronomers' efforts to study the Red Planet. Fobos appeared in the pictures in an irregular rock shape of 27x22x18
kilometers, one of the smallest satellites in the solar system, and so
small that if laid on the ground, Washington DC would easily accommodate
him.The
Moon circulates around Mars every 7 hours 39 minutes, which is faster
than the rotation of Mars around itself. The Moon completes three cycles
around Mars while Mars orbits itself only once. Mars completes one
cycle around its axis in 24 hours 40 minutes ,
Thus Phobos is the only moon in the solar system that revolves around
the planet more quickly than the rotation of the planet around itself. About two weeks after the landing of the Apollo Apollo 11 manned on the moon

Moon On July 20, 1969, the US Mariner 7 circled the Red Planet and took
the first close-up of the rough Phobos. On July 20, 1976, the US Viking
Viking landed on Mars. A year later, the Viking 1 picked up the first detailed picture of the surface of Phobos, revealing a nozzle on its surface.Vobos
was discovered by the American astrologer Asaph Hall on August 17, 1877
at the US Naval Observatory in Washington, DC. Six days after finding
the small outer moon, Hull discovered another moon orbiting Mars called
Deimos. The
two names were named Mars Mars Phobos and Demus relative to the sons of
the god of war in the Greek mythology of Ares, which was known as Mars
in Roman mythology. Phobos (panic or fear) and Demos (terror or terror) who accompanied their father in battle. The images from the spacecraft orbiting Mars show that Fobos is apparently torn by gravitational pull from Mars. On the moon there are long, shallow grooves that may be caused by the tidal interactions with its mother galaxy. Phobos
approaches Mars about 6.5 feet every 100 years, so scientists predict
that within 30 to 50 million years, it will either collide with the red
planet or be torn into pieces and spread in space in the form of a ring
around Mars like the rings of Saturn's famous planet. Phobos
orbits the planet at a distance of about 5,954 kilometers above Mars,
and is the nearest satellite to the mother planet of any other moon in
the solar system. Despite
its proximity, Mars observers will see Phobos covering an area of the
sky estimated at one-third of the width of the full moon as seen from
Earth. On the contrary, the person standing on Phobos will see Mars dominating the horizon and covering a quarter of the sky. That the person standing on Mars, can see the solar eclipse due to the moon Phobos. However,
because the moon appears in the Martian sky so small that it does not
completely cover the sun any eclipse will be partially and simply. The crossing of Phobos across the Sun disk was photographed by several Mars spacecraft.
