Neptune the planet facts - Dryers

Neptune the planet, is made of ice, rock, gases and liquids. The atmosphere is 85% hydrogen, 13% helium, 2% methane. The methane absorbs red light making the atmosphere appear blue. There are trace amounts of ammonia and water ice in the atmosphere. The core is made of iron,nickle and silicates and is very hot, thousands of degrees, in fact. Beneath the atmosphere is a mantle made of liquid. That liquid is ammonia, methane and water. It is dense. The planet actually radiates twice as much heat as it receives from the sun due to the temperature at its core. Temperature of the atmosphere may be minus 218 degrees C. Thus you have atronomers referring to it as an icy planet.

Any professional astronomer or astro club.

Nibiru is a mythical planet, sometimes called planet X, based on the old idea that irregularities in the orbits of the outer known planets could only be explained by the existence of a further, large, undiscovered planet.

However this idea, which started in the 19th Century, lost credence when it was found that the supposed irregularities were simply due to miscalculation of the real mass of Neptune.

Then when small objects began to be discovered in the Kuiper Belt beyond Neptune, the idea of Planet X reappeared. One of these objects was Eris, a bit smaller than Pluto, and too small to be a Planet X.

Modern telescopes and techniques have now all but ruled out the idea that Planet X exists.

Edit:Update: Using the latest sensitive observations NASA has discussed the possible existence of a "super-earth" very very far out in an extreme orbit. They have not found it, but say that the orbits of objects beyond the Kuiper Belt seem to suggest its existence.

However the idea of a Planet X, or Nibiru, crashing into Earth, has again been dismissed.

according to current discovery (Neptune, Pluto & Uranus) are not planet but let me know according to indian astrology there are 9 planet but the planet which has been discovered as non planet by nasa is there anything writen anywhere that astrologers are talking about the planet among 9 planet is that the same planet which the nasa is talking about and also would like to make you aware that space craft known as puspak viman has been discovered where in india more that 5000 b.c that simply mean that we indian are more advance as per current technologies so definitely our ancient scientist who were called (Rissi) were aware of this discovery before and even though if they have describe about 9 planet that means 9 planet do exist and our current scientist and nasa had not yeat discovered it.

It's behind you

Currntly there is no way to go to planet Neptune, so I wouldn't really worry about the possibility

On July 15, a 14th moon of Neptune, provisionally called S/2004 N 1, was announced.
Outwards from Neptune, the inner moons are Naiad, Thalassa, Despina, Galatea, Larissa, S/2004 N 1 and Proteus.Next outward from Neptune, Triton is one of four moons in the solar system known to have an atmosphere. The thin nitrogen haze is thought to have evaporated off of the frozen surface.After Triton comes Nereid. Much further out than Nereid orbit five outer moons, Halimede, Sao, Laomedeia, Neso and Psmathe.

Never. It will always be the eighth planet (unless an impact by a large celestial body, possibly from the Kuiper Belt, knocks it closer to the Sun) as Pluto is not a planet.

No. Neptune is a planet. Pluto is a separate body, classified as a dwarf planet.

The atmospheric components of Planet Neptune is 74% hydrogen, 25% helium, 1% methane.

Hope this helps.
