Neptune of the sea, identified with the Greek Poseidon. The demand for a mythological name seemed to be in keeping with the nomenclature of the other planets, all of which, except for Earth, were named for deities in Greek and Roman mythology. Most languages today, even in countries that have no direct link to Greco-Roman culture, use some variant of the name "Neptune" for the planet. However, in Chinese, Vietnamese, Japanese, and Korean, the planet's name was translated as "sea king star" (), because Neptune was the god of the sea.

Neptune trojan side of the Trojans against the Greeks. As of 2018, the only named Neptune trojan is 385571 Otrera, after Otrera, the first Amazonian queen in Greek mythology. The amount of high-inclination objects in such a small sample, in which relatively fewer high-inclination Neptune trojans are known due to observational biases, implies that high-inclination trojans may significantly outnumber low-inclination trojans. The ratio of high- to low-inclination Neptune trojans is estimated to be about 4:1. Assuming albedos of 0.05, there are an expected Neptune trojans with radii above 40 km in Neptune's . This would indicate that large Neptune trojans are 5
