If the mass of all the moons around the planet were added up, it probably would not match the mass of Neptune’s largest moon, Triton. However they are small, even with the combined masses of all five they would still be less than half of Triton – the largest moon of Neptune. The possibilities for life may be more limited because the moon is that much more distant from the sun, but it is hard to say for sure without doing detailed examination of the moons.
