London, Oct 25 : A new study has suggested that an unusual pair of craters on Mars formed when a moon broke apart before crashing into the planet’s surface about a billion years ago.
According to a report in New Scientist, the alignment of two oval-shaped craters on Mars – one spanning 10 km and the other, 3 km – hints they might have been gouged out by a fallen moon that broke apart in the Red Planet’s atmosphere.
The two craters, which lie about 12.5 kilometers apart, share the same oval shape and nearly the same west-east alignment.
