Known under the names of Phobos and Deimos, Mars` moons are the only two satellites orbiting around this planet. However, some experts argue that these moons were not the only ones orbiting around the Red Planet. According to a new study, Mars may have had more than two moons, but Phobos and Deimos managed to outlive the other satellites.
A survey published in “Nature Geoscience” indicates that Mars may have had more than two satellites in the past. This theory is widely contested as it fails to explain certain facts.
According to the official narrative, Phobos and Deimos are two asteroids caught by the gravitational field of Mars. However, this story fails to explain the regular orbit of these planets. Scientists have looked for a viable narrative that will allow them to understand the origin of Mars` moons, but so far they didn`t manage to find any story that can solve the puzzle.
However, researchers from Royal Observatory in Belgium developed an evolutional model, suggesting that Phobos and Deimos were formed after a violent collision between a big asteroid and Mars. Nonetheless, this hypothesis is widely discredited because it fails to explain why Mars` two moons are so small. In our planet`s situation, scientists know for sure that Earth` moon was formed after an impact, but Phobos and Deimos should have been bigger in case they were born following a violent collision.
As wide as 14 and 8 miles, Mars` satellites are too small, and their size remains the primary reason to reject this theory. However, the new study argues that the impact formed another moon, about 125 miles wide, but this planet managed to escape Mars` gravitational field.
According to Pascal Rosenblatt, the lead researcher of the study, this big moon was created after the impact of a 1.250 mile-wide asteroid with planet Mars. The debris ejected into space was caught by the gravitational field of some big pieces of asteroid, forming at least three moons: Phobos, Deimos, and a third moon which managed to escape Mars` gravitational field.
The fact that Mars may have had more than two moons remains to be verified through further research. Japanese scientists plan to launch a mission to collect sediments from Phobos to see if this moon is made of the same rocks as Mars.
