ISRO, the national space agency, has shared a tiny footage on its social networking site with a caption, "The larger of the two Martian moons, Phobos, is seen travelling West to East over Mars in its typical orbit."
The images were taken from an altitude of 66,275 km above the surface of the Red Planet, it said. Phobos along with the Mars' another natural satellite Deimos was discovered by mankind in 1877.
Did you see that? It moved! Oh, it's just Phobos. https://t.co/vaY7w5JjW0— ISRO's Mars Orbiter (@MarsOrbiter) October 14, 2014
According to NASA, Phobos, which is 27 by 22 by 18 km in diameter orbits the red planet three times a day. Phobos was nearing Mars at a rate of 1.8 m every hundred years and at that rate, it would either crash into the red planet in 50 million years or break up into a ring, according to the US national space agency.
