The two moons in question are Naiad and Thalassa, both around 100 kilometres or 62 miles wide, which race around their planet in what NASA researchers are calling a "dance of avoidance".. Their strange orbit was first detected by NASA researchers in November 2019. Naiad, the last satellite discovered, is about 54 kilometers (33 miles) in diameter and orbits Neptune every 7 hours and 6 minutes about 23,200 kilometers (14,400 miles) above the clouds. "An animation showing how the two moons' orbits compliment each other, ensuring the two do not collide when they cross paths. Neptune Moon Dance: This animation illustrates how the odd orbits of Neptune’s inner moons Naiad and Thalassa enable them to avoid each other as they race around the planet.
The team say the observations also offer clues to the composition of these inner moons by calculating their mass and their densities. The value is the radius in km of the said object at the Equator.The Escape Velocity of the object is 101 km/h. They maintain the peace by never getting too close. According to the researchers, these calculations suggest the moons could consist of water ice. Thalassa, in contrast, takes 7.5 hours. Its density has been calculated at being 1.3.

More importantly, however, the pair are incredibly close together, celestially-speaking, with orbits that are only 1,150 miles apart. Naiad is a moon of planet Neptune and is likely a rubble pile that has re-accreted from fragments of the original moons of Neptune that collided after the moon Triton was captured.
