Eclipse on Mars: See the mesmerising DOUBLE ECLIPSE snapped by NASA’s Curiosity rover

When Phobos passed in front of the Sun, the eclipse was much more discernible and exciting to observe.

Phobos is estimated to measure roughly seven miles across (11.5km), making it about three times bigger than Earth’s Moon.

But unlike our round Moon, Phobos is an irregular satellite and orbits Mars from an incredibly close distance of about 3,700 miles (6,000km).

The moon’s orbit is also gradually shrinking at a rate of about 6.5ft (two metres) every century.
