Neptune facts

While investigating facts about Neptune, I found out little known, but curios details like:

The D-Day(June 6) Crossword Panic of 1944 in which, in the 35 days before the invasion, 5 obscure, top-secret code words appeared in the Daily Telegraph puzzles..The words 'Utah, Omaha, Overlord, Mulberry and Neptune' triggered a MI5 investigation.

The planet Neptune may have a liquid diamond ocean with solid floating diamond-bergs.

In my opinion, it is useful to put together a list of the most interesting details from trusted sources that I've come across. Here are 50 of the best facts about Neptune I managed to collect.

  1. The fade-out at the end of Holst's Neptune was achieved by slowly closing the door on a female choir as they sang in another room.

  2. Uranus and Neptune are not "Gas Giants" as is commonly believed, but belong to a separate category of giant planets called "Ice Giants." This is because less than 20% of their mass is made up of hydrogen and helium. True gas giants like Jupiter and Saturn are over 90% hydrogen and helium.

  3. Neptune has the strongest winds in the Solar System: 2,100 km/hour (1,304 mph).

  4. Due to incredibly high pressure on Uranus and Neptune, it is theorized that oceans of liquid diamond exist on the surface of the planet, with solid "diamond-bergs" floating on the surface

  5. It might rain liquid neon on Jupiter and snow diamonds on Neptune

  6. The Voyager missions were launched when they did to take advantage of a unique planetary arrangement that allowed flight time to Neptune to be reduced from 30 years to 12. This alignment occurs every 175 years.

  7. On July 11th, 2011, Neptune completed its first full orbit around the sun since its discovery in 1846

  8. Triton, the largest moon of Neptune, is the only moon in our solar system with a retrograde orbit - an orbit in the opposite direction its planet, and is thus thought to be a dwarf planet that Neptune caught from the Kuiper belt.

  9. Since it was discovered 170 years ago, Neptune has completed just 1.04 orbits of the sun.

You can easily fact check it by examining the linked well-known sources.

Caltech researchers found evidence of a ninth planet which orbits the Sun 20 times farther than Neptune where one full orbit takes between 10,000 to 20,000 years to complete.

Because Pluto’s orbit is so elliptical, it is actually closer to the sun than Neptune for 20 years every 248 years - source

The Neptunes Cup sponge grew so big that they were commonly harvested to be used as baths for infants. Overharvesting for this use contributed largely to their extinction until they were rediscovered in 2010.

Neptune was the first planet to get its existence predicted by calculations before it was actually seen by a telescope.

The surface gravity of Venus, Saturn, Uranus, and Neptune are very similar to Earth's, whilst Mars' is only about 1/3.

When sailors in the Navy pass over the equator for the first time, there is a "Crossing the Line" ceremony and the sailors receive the title "Shellbacks" and "Sons of Neptune." They get a certificate and its "signed" by Davy Jones and Neptune.

Neptune emits more light than it receives from the Sun.

Neso (moon of Neptune) is the farthest moon from its planet in the Solar System. It takes 26 Earth years to orbit Neptune planet once and it is as far away from the planet as the Earth is to Venus.

Interesting facts about neptune

Neptune was discovered through mathematical predictions instead of monitoring the night sky.

Neptune has its own heat source, which is a good thing because it only receives 1/900 of the sun's energy that the Earth receives.

The two other fountains in Piazza Navona include Fontana del Moro, and Fountain of Neptune.

The wind on Neptune can reach speeds of 1,240 miles per hour. This is equal to three times the speed of Earth's worst hurricanes.

Neptune has at least 14 moons, with the largest being Triton, discovered by William Lassell in 1846 one day after the discovery of Neptune. The most distant moon of Neptune is Neso which takes 26 years to make one trip around the planet.

Winkler decided to name this new element after the newly discovered planet Neptune, but the name was already taken.

Neptune has 14 known moons including Nereid, Proteus, Triton, Thalassa, Despina and Galatea. Neso is so far from Neptune it takes it 26 years to orbit the planet only once.

Because of the methane gas in Neptune's atmosphere, the planet appears to be blue. This actually occurs partly because of the ability of atmospheric methane gas to absorb red light.

Neptune is NOWHERE NEAR the edge of the solar system. It is roughly 1/3,333rd the distance.

Gas giants have been found around more than a thousand stars by the Kepler mission and are often referred to by such names as Hot Jupiters, Super Jupiters and Giant Neptunes.

(coincidentally) just as humanity's space technology was emerging, Jupiter, Saturn, Uranus, Neptune, and Pluto were all aligning, something that only occurs every 175 years enabling the humble Voyager spaceships to visit all but Pluto.

Neptune has a mass 17 times greater than that of Earth's, but its mass is only 1/19th of Jupiter's.

Triton, is Neptune's largest moon. It has ice volcanoes but it is so cold that the mixture instantly freezes and falls back to the surface as snow. Triton is considered to be one of the coldest of all objects in our solar system because it is gets so little sunlight and reflects what it does get. It is about -400 degrees Fahrenheit.

Jupiter, Saturn, Uranus and Neptune are made up of mostly hydrogen and helium and are considered to be gas giants.

Pluto's year, which is the time taken to complete one orbit around the Sun, is 248 Earth years. For 20 years of its orbit Pluto is closer to the Sun than Neptune.

There are demonyms for beings from each planet: Venus - Venusian, Earth - Earthling or Terran, Mars - Martian Jupiter - Jovian, Saturn - Saturnian, Uranus - Uranian, Neptune - Neptunian, Pluto - Plutonian, Sun - Solarian, Earth's Moon - Lunarian or Selenite, and so on..

Even though Neptune has a greater mass than Uranus, it has a smaller diameter.

The words Utah,Omaha,Overlord,Mulberry,Neptune,Gold and Sword all appeared in The Daily Telegraph's crossword in 1944. Every one of these word's were codenames used in preparation for the D-Day invasion of Normandy. The crossword creator was interrogated (spy?) but was found innocent.
