The smallest moon in the Solar System is called the Prometheus Moon. The oxygen in Earths atmosphere is biological in nature, whereas Europas is not. . Both moons have a lot of craters, but Deimos is the smoother of the two. From deep below the soil at Earths polar regions to Plutos frozen heart, ice exists all over the solar systemand beyond. Following the completion of this phase, they will begin the next phases, which include detailed mission planning, preparation, and crew selection, as well as the launch and arrival of the mission. The formation of Deimos is highly disputed and controversial. Phobos and Deimos bear more resemblance to asteroids than to Earth's moon. Deimos ("DEE mos") is the smaller and outermost of Mars' two moons. The inner part of the ring formed a large moon.
