It has been around 20 days after ISRO has successfully made Mangalyaan enter the orbit of the Red Planet Mars. ISRO’s Mars Orbiter sent pictures of Phobos on Tuesday — which is the largest of the two natural satellites that orbits around the Mars.
ISRO, the national space agency, has shared a tiny footage of the Moon in its social networking site followed by a caption, “The larger of the two Martian moons, Phobos, is seen travelling west to east over Mars in its typical orbit.”
The images of the moon is taken from an hieght of 66,275 km above the surface of the Red Planet. It is said Phobos along with the Mars’ another natural satellite called Deimos was discovered in 1877 by the mankind. According to NASA, Phobos is 27 by 22 by 18 km in diameter orbits the red planet thrice a day.

Also the study in US national space agency, it suggests that Phobos is nearing Mars at a rate of 1.8 m every hundred years and with this rate, it would either crash into the red planet in around 50 million years from now or break up into a ring.
