The density of Neptune is more or less 1.64 gr/cm[math]^3[/math].

There is no identifiable surface on Neptune, as is the case on Earth, Mars and other terrestrial planets. Answer to: The average density of the planet Uranus is 1.27 times 10^3 kg / m^3. Neptune Observational Parameters Discoverer: Johann Gottfried Galle (based on predictions by John Couch Adams and Urbain Leverrier) Discovery Date: 23 September 1846 Distance from Earth Minimum (10 6 km) 4305.9 Maximum (10 6 km) 4687.3 Apparent diameter from Earth Maximum (seconds of arc) 2.4 Minimum (seconds of arc) 2.2 Mean values at opposition from Earth Distance from Earth (10 6 km) … Neptune has been the subject of one space-probe fly-by as of 2019: NASA's Voyager II in 1989. The atmosphere, composed mostly of hydrogen and helium with trace amounts of methane and ammonia, increases in density toward the planet’s interior. © 2020 SmartConversion. It is the windiest planet, with surface wind speeds reaching up to 1,300 miles per hour.

Examples: Neptune has almost the density of Pluto, which is astounding, because Neptune is a gas giant and Pluto is solid. decimal places. The ratio of the mass of Neptune to that of Uranus is 1.19. For comparison, the density of water is 1 gr/cm[math]^3[/math]. Uranus has a density of 1.27 g/cm³ Neptune has a density of 1.638 g/cm³ Earth for comparison has a density of 5.515 g/cm3 Interesting Neptune facts include that it is the eighth and farthest planet from the sun, and much more. Like the other outer planets, Neptune has a low density—only about 1.6 times the density of water. The rings of Neptune were discovered in 1989 by the Voyager 2 spacecraft and are tenuous, faint and dusty, and resemble the rings of Jupiter more closely than those of Saturn or Uranus. All Rights Reserved. Neptune is the most dense. It is the third most massive planet in the solar system, after Jupiter and Saturn.

Version 4.0 - Last updated: Sunday, August 16, 2015. Please enter one value, the other values will be calculated. Neptune’s mass is about 1.2 times greater than Uranus’s, however, and more than 17 times greater than Earth’s.

In other words, if you put Neptune in a huge bathtub, it will sink.

Neptune possesses five known rings, each named for an astronomer who contributed important work on the planet: the Galle, Le Verrier, Lassell, Arago and Adams rings.
