Mars is not like some other planet in our photo voltaic system because of its distinct ellipsoidal form, having completely different sizes alongside all three axes. Whereas it has two tiny moons at the moment, the Pink Planet might need as soon as hosted a a lot bigger moon, based on a principle proposed by Michael Efroimsky, an astronomer on the U.S. Naval Observatory in Washington, D.C. This moon, probably named Nerio, might have performed a major position in shaping the planet’s present topography, together with its huge highlands and deep valleys.
Mars distinctive panorama
Mars is residence to a number of the most excessive options within the photo voltaic system, together with the Tharsis bulge, a area about 5,000 kilometres extensive and as much as 7 kilometres excessive. On the other facet of the planet lies Terra Sabaea, one other highland space, together with Syrtis Main, a large defend volcano.
These distinctive options may very well be remnants of Mars’ historical moon elevating tides within the planet’s magma oceans, very like how Earth’s moon raises tides in our seas, based on a research printed within the on-line journal arXiv.
The thriller of Nerio’s disappearance
In accordance with Efroimsky, the moon Nerio might have been destroyed by a collision or scattered out of the photo voltaic system because of gravitational interactions. Whereas such occasions had been widespread within the early photo voltaic system, no clear proof, equivalent to crater strings, factors to this occurring on Mars. It is doable geological actions might have erased any indicators of Nerio’s existence.
Whereas the speculation stays speculative, it means that Mars’ dramatic panorama might have been formed by each Nerio and subsequent geological processes. Efroimsky encourages additional analysis to discover the potential proof for this misplaced moon and its impression on Mars’ distinctive options.
