|ARE THEY IRREGULAR MOONS OR IRREGULAR SATELLITES?|
In astro-speak, they are satellites. There is only one Moon and it is the Earth's satellite.
However, in everyday useage, the word "satellite" has come to be associated with man-made orbiting devices, while "moon" refers to any natural satellite of a planet. So, they are strictly irregular satellites but everyone will know what you mean by irregular moons.
Is this a big deal?
Not at all. As long as we know what we're talking about, both names are fine. Increasingly, they are used interchangably by planetary astronomers (who should know better!).
