Name of the nearest satellite to Neptune

Triton for short, with the names triton 1 to triton 9. Their diameters are 2720km, 340km, 58km, 80km,142km,150km,188km, 416km and 28km respectively. Triton is a very special satellite. Its diameter is slightly smaller than that of the moon. It is one of the four satellites with an atmosphere in the solar system. It is close to Neptune, but retrograde. 1989 Voyager 2 found that it has almost all the characteristics of a planet: not only all the weather phenomena of a planet, but also the landform and internal structure similar to a planet. Its polar cap is bigger than Mars, and the volcano on it is also very active. Surprisingly, it also has a magnetic field that only planets have. Triton is also remarkable among Neptune's satellites, because it is the largest irregular satellite in the solar system, with a diameter of 4 16KM and an irregular shape.

Neptune has at least nine known satellites: eight small satellites and Triton. Triton is the largest satellite in the solar system. Satellite Distance Radius Discovery Date (km) (km) Triton 48000 29 Voyager 21989 Triton 40 Voyager 21989 Neptune Satellite

Edit paragraph 3. triton (shell)

Voyager 2 21August 24, 989 was shot at a distance of 530,000 kilometers from Triton, a satellite orbiting Neptune. It is the largest satellite of Neptune. It is one of the coldest celestial bodies in the solar system, with complex geological history and relatively young surface. 1846 65438+1October 10 Triton was discovered in william russell (this is17th day after Neptune was discovered). Russell thinks he also discovered Neptune's ring. Although it was later discovered that Neptune did have a ring, Russell's discovery was still doubtful, because in fact Neptune's ring was too dark for Russell to find with his instrument.

Edit paragraph 4. triton (shell)

Triton is the third largest satellite of Neptune, and its eccentricity is the largest among the satellites found so far, reaching 0.75438+02. The nearest distance to Neptune is 65,438+0,300,000 kilometers, and the farthest distance is 9,700,000 kilometers. Therefore, it is considered to be a Cooper belt object attracted by Neptune's gravity.

5. 1 Triton III (Naiad)

Triton is the latest known satellite of Neptune. It is the last Neptune satellite discovered by Voyager 2 in 1989. Triton III, Triton IV, Triton V and Triton VI all have irregular shapes. Triton is 470 kilometers in diameter, with a rotation time of 7.066 hours and a distance of 237 1 10 kilometers from Neptune.

5.2 Thalassemia

Triton is the second closest satellite to Neptune and was discovered by Voyager 2 on 1989. The diameter of Triton is 540 kilometers, which is a little longer than Triton. Its rotation time is 7.476 hours and it is 255890 kilometers away from Neptune.

5.3 Triton V (Despina)

Triton is the third closest satellite to Neptune and was discovered by Voyager 2 on 1989. Like the diameter of Triton, Triton has a diameter of 470 kilometers and a rotation time of 7.066 hours. It is 282040 kilometers away from Neptune.

5.4 Galatia

Triton is the fourth closest satellite to Neptune and was discovered by Voyager 2 on 1989. Triton is 900 kilometers in diameter, with a rotation time of 8.032 hours and a distance of 376,950 kilometers from Neptune.

5.5 triton seven (Larissa)

Triton is the fifth closest satellite to Neptune and was discovered by Voyager 2 on 1989. The diameter of Triton is 1000 km, the rotation time is 13 5438+02 hours, and it is 49 1800 km away from Neptune.

5.6 Transformers (Proteus)

Triton is the sixth closest satellite to Neptune and was discovered by Voyager 2 on 1989. The diameter of Triton is 2 190 km, and its rotation time is 1. 122 days, which is slightly longer than the rotation time of the earth. It is 939440 kilometers away from Neptune.

Edit paragraph 6. Other small satellites

Halimede, Psamathe, Sao, Laomedeia and Neso are the first external small satellites. Halimid was discovered in 2002. Psamathe is the second small external satellite, which was discovered in 2003. Sao is the fourth external small satellite, which was discovered in 2002. Lao Media is the last small external satellite, which was discovered in 2002. Neso is the fourth small external satellite, which was discovered in 2002.
