In Greek mythology, Proteus ( Πρωτεύς ) is an early sea-god, one of several deities whom Homer calls the " Old Man of the Sea ".

Proteus ' name suggests the " first " ( from Greek " πρῶτος "-protos, " first "), as protogonos ( πρωτόγονος ) is the " primordial " or the " firstborn ".

Proteus of Egypt is mentioned in an alternate version of the story of Helen of Troy in the tragedy Helen of Euripides ( produced in 412 BC ).

The play's king ( never seen ) is only marginally related to the " Old Man of the Sea " and should not be confused with the sea god Proteus.

Proteus is the name of the submarine in the original story by Otto Klement and Jay Lewis Bixby, which became the basis for the 1966 film Fantastic Voyage and Issac Asimov's novelization.

John Barth's novelette " Menelaiad " in Lost in the Funhouse is built around a battle between Proteus and Menelaus.

Because of the great diversity of forms found in this group, the Proteobacteria are named after Proteus, a Greek god of the sea, capable of assuming many different shapes, and it is therefore not named after the genus Proteus.

Silver-footed Thetis ( Ancient Greek: ), disposer or " placer " ( the one who places ), is encountered in Greek mythology mostly as a sea nymph or known as the goddess of water, one of the fifty Nereids, daughters of the ancient one of the seas with shape-shifting abilities who survives in the historical vestiges of most later Greek myths as Proteus ( whose name suggests the " first ", the " primordial " or the " firstborn ").

Proteus is the largest irregularly shaped moon.

It is likely, however, that Merrick suffered from the very rare Proteus syndrome.

The father of Phrygian Dymas is given as one Eioneus, son of Proteus, by some ancient mythographers ( scholiasts on Euripides ).

Mr. Boyer works for Proteus and is a member of Kiwanis.

Haydon-Baillie is the owner of the super yacht Brave Challenger and uses the same Rolls-Royce Proteus Marine engines as the SRN4s.

Unlike neurofibromatosis, Proteus syndrome affects tissue other than nerves, and it is a sporadic disorder rather than a genetically transmitted disease.

Proteus (; Greek: Πρωτεύς ), also known as Neptune VIII, is the second largest Neptunian moon, and Neptune's largest inner satellite.

Discovered by Voyager 2 spacecraft in 1989, it is named after Proteus, the shape-changing sea god of Greek mythology.

Proteus is probably not an original body that formed with Neptune ; it may have accreted later from the debris created when the largest Neptunian satellite Triton was captured.

Proteus is the largest of the regular prograde satellites of Neptune.

The surface of Proteus is dark — its geometrical albedo is about 10 %.

The second landform found on Proteus is linear features such as scarps, valleys and grooves.

The largest of them is Proteus.

Naiad, the closest regular moon, is also the smallest among the inner moons, while Proteus is the largest regular moon.

Throughout the 1990s, the team of Dark Horse and Studio Proteus was one of the two largest manga publishers in the U. S., competing with Viz.

Saturn's moon Mimas has a more spherical shape despite being slightly less massive than Proteus, perhaps due to the higher temperature near Saturn or tidal heating.

Pharos is the only named surface feature on this moon: the name is Greek and refers to the island where Proteus reigned.

In order of distance from Neptune, the regular moons are Naiad ( moon ), Thalassa ( moon ), Despina, Galatea, Larissa and Proteus.

Proteus ( moon ) | Proteus, a moon of Neptune, is irregular, despite being larger than the spheroidal Mimas ( moon ) | Mimas.

Heat energy, from gravitational collapse, impacts, tidal forces, or radioactive decay, also factors into whether an object will be spherical or not ; Saturn's icy moon Mimas is spheroidal, but Neptune's larger moon Proteus, which is similarly composed but colder because of its greater distance from the Sun, is irregular.

Proteus circles Neptune in a nearly equatorial orbit at the distance of about 4. 75 equatorial radii of the planet.

Proteus was discovered from the images taken by Voyager 2 space probe two months before its Neptune flyby in August 1989.

Proteus orbits Neptune at the distance approximately equal to 4. 75 equatorial radii of the planet.

Proteus is slightly elongated in the direction of Neptune, although its overall the shape is closer to an irregular polyhedron than to a triaxial ellipsoid.

Proteus, like the other inner satellites of Neptune, is unlikely to be an original body that formed with it, more probably having accreted from the wreak rubble that remained after Triton's capture.

Other moons of Neptune are also named for Greek and Roman water gods, in keeping with Neptune's position as god of the sea: either from Greek mythology, usually children of Poseidon, the Greek Neptune ( Triton, Proteus, Despina, Thalassa ); classes of minor Greek water deity ( Naiad, Nereid ); or specific Nereids ( Halimede, Galatea, Neso, Sao, Laomedeia, Psamathe ).
