'Phobos' looks like potato NASA shares a picture of Mars Moon

The official Instagram handle of NASA has shared the picture of Mars moon ‘Phobos’ that looks like a potato with a caption ‘you say potato, we say Mars Moon’.

“This is an image of Phobos, the largest of Mars’ two raggedy moons, as seen by the @UAHiRISE camera abroad our Mars Reconnaissance Orbiter spacecraft ,” wrote NASA.

The picture has been taken from 6,800 kilometres (4,225 miles) above the surface, the image shows a pockmarked celestial; body with a large impact basin called Stickney crater. The grooves seen along its side could be the result of tidal forces – the mutual gravitational pull of the planet and the moon. Scientists have calculated that tiny Phobos is nearing Mars at a rate of 1.8 metres (6 feet) every century, meaning it will either crash into planet in 50 million years or break up into a ring of debris.

Phobos was discovered in 1877 by American astronomer Asaph Hall, and one popular theory is that it might be a captured asteroid. In Greek mythology, Phobos and Deimos are the twin sons of Ares, wrote NASA.
