41: 314: 4437: 289:(pictured right), is unknown and remains controversial. One theory is that the moons are captured asteroids. However, the moons' near circular orbits and low inclination relative to the Martian equator are not in agreement with the capture hypothesis. The detection of minerals on Phobos similar to those in the Martian 305:
remaining close to Mars. This figure lies within the estimated mass range necessary to form the two moons, as other data suggests that only 1% of the mass of an accretion disk successfully forms moons. There are several other large impact basins on Mars that could have ejected enough debris to form the moons.

While estimates of the mass ejected by a large, Borealis-size impact vary, simulations suggest that a body approximately 0.02 Mars masses (~0.002 Earth Masses) in size is capable of producing a sizable debris disk in Martian orbit, on the order of 5×10 kg, with a significant fraction of the material

However, some authors have instead argued that the inverse is more likely to be true, and that rather than the North Polar Basin being an impact basin, the Southern Hemisphere of Mars may have actually the site of the impact instead, and the thickness of the Southern Hemisphere crust was as a result

One possible explanation for the basin's low, flat and relatively crater-free topography is that the basin was formed by a single large impact. Two simulations of a possible impact sketched a profile for the collision: low velocity—6 to 10 km (3.7 to 6.2 mi) per second—oblique angle and a

and causing upwellings which further increase the amount of melting at the impact site. Overall, such an event would actually increase the rate of cooling of the Martian interior. The lack of magnetic anomalies observed in the northern hemisphere could be explained by such an impact, as the shock

This impact would have resulted in significant crustal melting and a general increase in the rate of crustal formation for a period of 40 million years following the impact. Such a large impact would have disturbed the

The moons of Mars: Phobos and Deimos. Phobos is the larger of the two moons, and is the closer of the two to Mars. Phobos has an average radius of 11 km, while Deimos has an average radius of 6 km.

Lomonosov crater, the most likely candidate for the impact that produced the tsunami. It is 150 km in diameter, and is a prominent feature of the Borealis basin.

Because the Borealis basin covers 40% of the surface of Mars, and much of the Northern Hemisphere, many currently recognized regions of Mars lie within it:
