A new research has provided insights into tiny moons of Mars-Phobos and Deimos — with respect to their origin and the expected ring-like structure of Mars similar to Saturn.
According to the recent study by Purdue University says that Mars will retrieve the rings when one of the moons incorporates.
As per the new study by Purdue scholar Andrew Hesselbrock said that debris was released into space due to asteroid collision with Mars. The collision has taken place around 4.3 billion years ago and was the starting point of moon formation in the Red Planet.
Big Moon Splinters into ring
The gigantic impact has led to the formation of the big moon and its impact was experienced by Mars some billions of year ago. Although it has formed a giant moon, it was unstable and slivered into a larger ring.
It also resulted in the cycle of spatial residue alternating between two structures — a planetary ring and a moon form resulting from the clustering.
The study was published in the journal Nature.
Ring formation and after
The new model also says that small moon formation from the ring was also accompanied by the drifting of the planet to the formation of the moon. When rings blend to form smaller moons, the remaining residue is released into Mars surface or pushed into space.
This process is recurring one as the small moons break into rings and later on they clump together to form the moon.
Phobos facing disintegration
The model reveals that Phobos is now going closer to Mars and it may break apart when it reaches the nadir of Roche limit. New rings will be due in a span of millions of years.
What is amazing is that the moon, when it takes rebirth from a ring, would decrease in size at least five times the former size.
Deimos is Harmless
In contrast to the disintegration threat faced by Phobos, the other moon Deimos is safe. Because it is very far to be a part of the regenerative cycle.
By being far the effects of Martian tidal forces will not affect its orbit and it will keep widening the distance from Mars.
The model proposed by Purdue is good at the simulation stage and is not yet proven, though it can become a big possibility.
