Neptune XIV away from Larissa since then because the former two are outside Neptune-synchronous orbit (Neptune's rotational period is 0.6713 day) and are thus being tidally accelerated, while Larissa is within and is being tidally decelerated.

The discovery team plans to submit a name proposal to the International Astronomical Union based on a figure from Greco-Roman mythology with a relationship to Poseidon or Neptune, the god of the sea, consistent with the naming of other moons of Neptune.
