No. A crater is a circular depression in the ground made by an impact or explosion. The moons of Mars are captured asteroids.
Multi-ring basin craters are the largest type of crater found in the solar system. They are caused by the asteroid hitting a hard, rigid surface and causing ripples in the layer under the surface.
because the objects hitting it would hit then the impact would create a circular shape
The South Pole-Aitken basin (not "Aitken crater") on the far side of the moon, at 1,600 miles across, is not only the largest known impact crater on the moon but one of the largest in the solar system. It is also believed to be the moon's oldest and deepest (over 8 miles deep).
The greater the crater density, the older the surface must be old.
The largest known crater in North America is located in Sudbury, Ontario, Canada. It has a diameter of 250 km, the second-largest known crater on Earth, and was formed by a meteorite impact 1.849 billion years ago.

All moons are susceptible to impacts from asteroids or meteoroids, they've most likely all been hit several times. Mimas is the one with a huge crater, from an impact that almost ripped it apart. Mimas now looks like the Star Wars 'death star'.
Mimas and Tethys, both moons of Saturn, have spectacularly large craters which dominate certain views, and rival the Death Star (and maybe inspired it!). Some astronomers have questioned how an impact crater such a large fraction of the moons' diameters did not completely break them apart. Odysseus crater on Tethys is 450km in diameter; Herschel crater on Mimas is about 139km across.
The Daily Orbit - 2012 Australia Is Home to the Third Largest Impact Crater 1-119 was released on: USA: 18 February 2013
The Bailly crater on the Moon was most likely formed by the impact of a large asteroid or comet colliding with the lunar surface. The impact would have created a crater with a central peak and terraced walls, features commonly seen in larger impact craters. Bailly crater is one of the largest craters on the Moon and is estimated to have formed billions of years ago.
