Mars could get Saturn-like rings in 2-7 crore years: Study
An analysis of data from a Mars-orbiting satellite suggests that Mars is building Saturn-like rings from interplanetary dust and fragments from its disfigured moons, Phobos and Deimos. Researchers claim that the ring formation could take around 2-7 crore years owing to the two moons being gradually chipped away as they are drawn closer to the red planet by its gravity.
