Neptune's mass of 1.0243 × 10 26 kg [8] is intermediate between Earth and the larger gas giants: it is 17 times that of Earth but just 1/19th that of Jupiter. [g] Its gravity at 1 bar is 11.15 m/s 2, 1.14 times the surface gravity of Earth, [71] and surpassed only by Jupiter. [72] Neptune's equatorial radius of 24,764 km [11] is nearly four ...

Neptune is 17 times the mass of Earth and is slightly more massive than its near-twin Uranus, which is 15 times the mass of Earth and slightly larger than Neptune. [a] Neptune orbits the Sun once every 164.8 years at an average distance of 30.1 astronomical units (4.50 × 10 9 km).
All but the outer two are within Neptune-synchronous orbit (Neptune's rotational period is 0.6713 day or 16 hours [20]) and thus are being tidally decelerated. Naiad, the closest regular moon, is also the second smallest among the inner moons (following the discovery of Hippocamp), whereas Proteus is the largest regular moon and the second ...
Galatea / ɡ æ l ə ˈ t iː ə /, also known as Neptune VI, is the fourth-closest inner moon of Neptune, and fifth-largest moon of Neptune. It is named after Galatea , one of the fifty Nereids of Greek legend , with whom Cyclops Polyphemus was vainly in love.
The ice giants Uranus and Neptune live up to their name. Although humans have only ever sent one spacecraft (Voyager 2) toward these far-flung worlds, scientists have a pretty good idea that these ...
Laomedeia / ˌ l eɪ ə m ə ˈ d iː ə /, also known as Neptune XII, is a prograde irregular satellite of Neptune. It was discovered by Matthew J. Holman , et al. on August 13, 2002. [ 6 ] Before the announcement of its name on February 3, 2007 (IAUC 8802), it was known as S/2002 N 3 .
Naiad / ˈ n eɪ ə d /, (also known as Neptune III and previously designated as S/1989 N 6) named after the naiads of Greek legend, [10] is the innermost satellite of Neptune and the nearest to the center of any gas giant with moons with a distance of 48,224 km from the planet's center. Its orbital period is less than a Neptunian day ...
