Planet Neptune

Neptune's great dark spot is a giant storm, similar to Jupiter's Great Red Spot. It is a large area of high pressure that causes gases to circulate rapidly, creating the appearance of a dark spot on the planet's surface.

Its mainly hydrogen (80%) and helium (19%). There is also around 1% methane in the atmosphere, which absorbs the red light and gives it its blue colour and there are some traces of Hydrogen deuteride and Ethane.

There are also various ices present, such as ammonia, water and ammonium hydrosulfide.

Neptune is a gas giant composed mainly of hydrogen and helium, so it doesn't have a surface to land on. Additionally, the gases present in its atmosphere are not conducive to human life, so it would be impossible to smell anything on Neptune.

Neptune's surface temperature is extremely cold, averaging around -353°F (-214°C). However, its core can reach temperatures of around 7,200°F (4,000°C) due to the intense pressure and heat generated from gravitational forces.

Neptune, the planet, was not "founded" by anyone as it is a natural astronomical body. It was discovered by German astronomer Johann Galle, British mathematician John Couch Adams, and French mathematician Urbain Le Verrier in 1846 through mathematical predictions based on perturbations observed in the orbit of Uranus.

Yes, Neptune has powerful and persistent storms, such as the Great Dark Spot and the Scooter. These storms are driven by high-speed winds that can reach up to 1,500 miles per hour, making them some of the fastest winds in the solar system.

Average distance from the sun is 4,488,000,000 km

The distance from the Sun to Neptune is 4,504,300,000 kms

Light travels 9,460,730,472,580,800 kms a year

So light would take just over four hours to get from the Sun to Neptune.

Most of us have taken a 4-hour road trip. So imagine driving solidly for over four years. That's how long you'd have to travel for (at the speed of light) to get to the next star (Proxima Centauri).

Some interesting facts about the planet Neptune are: * It was named after the Roman sea god * Neptune is the stormiest planet with 1,240 miles per hour winds * Neptune is a sea blue color due to the methane gas in its atmosphere * Neptune goes around the Sun every 165 Earth Years * Neptune has 8 known moons * Neptune is known as the Ice Giant

It isn't even 1 light year. Its 243 light minutes.

Neptune has a mass of 1.0243×1026 kilograms, or about 17.147 times that of Earth. Wikipedia has additional information, and a link is provided below to their post on this, the new "last planet" now that Pluto has been "demoted" to a planetary body. Neptune's density is 1.638 g/cm³. That means that in every cm cubed it weighs 1.638 grams.

Neptune is the eighth planet from the Sun in the Solar System, and was named for the Roman god of the sea (equivalent to the Greek Poseidon). The name was originally proposed by Urbain Le Verrier, a French mathematician who specialized in celestial mechanics who was one of those who first identified Neptune as a planet.

Neptune is the fourth-largest planet in our solar system, with a diameter of about 30,775 miles. It is composed mainly of gas, primarily hydrogen and helium, with a small rocky core. Its atmosphere contains traces of methane and other gases that give it a blue tint.

Neptunes features are:

. Gassy

. Blue

. Neptune has one storm system know as the Great Dark Spot. The storm system is thought to be rotating counter clockwise due to a spiral shape of both the dark boundary and the white cirrus surrounding the spot.

.Neptune has a set of four rings which are very narrow and faint. They are made up of dust particles made by tiny meteorites that have crashed into Neptune's moons.

Astronomers predicted the existence and orbit of Neptune based on discrepancies in the orbit of Uranus. These discrepancies suggested the gravitational influence of another planet beyond Uranus, leading to the discovery of Neptune in 1846.

Neptune is believed to have a rocky core made of silicate and metal, surrounded by a mantle of water, ammonia, and methane ices. Above the mantle is a thick atmosphere of hydrogen, helium, and traces of methane, giving Neptune its blue color.

The gravity on Neptune is higher than on Earth. Neptune is a larger and more massive planet, so its gravitational force is stronger. If you were on Neptune, you would weigh more than you do on Earth.

When Neptune was discovered by Johann Galle in 1846 , there were several competing names including Janus, Oceanus and Le Verrier's Planet (for the French astronomer who accurately predicted its position in 1845). Using a Roman name matched the European tradition (only Uranus has a Greek name). The name Neptune, for the Roman god of the sea, was finally adopted later in 1846.

The bright blue color was only later verified.

Life as traditional Earth biochemistry knows it? No. Life based on alternative theories of biochemistry, yes. Beneath its icy surface Triton is teeming with volcanic and tectonic activity. There are ample amounts of ammonia, water, and nitrogen flowing below the surface, in much the same way lava flows below the surface of the earth. Triton also possesses a thin nitrogen atmosphere. Alternative theories of biochemistry suggest that it is possible that life could form on Triton using ammonia (which has a low freezing point), in much the same way early life forms on earth used water. Yes, it is possible. However given the harsh, gelid conditions, and our current understanding of life in general and its rarity, it is still unlikely.

The calculation for weight is universal gravity times the mass of the person times the mass of the planet divided by the radius of the planet squared. This means that 154 lbs. on Earth equals 175.95 lbs. on Neptune.

Neptune was named after a Roman god, but than name was proposed by a German astronomer.

Uranus takes 84 Earth years to complete one orbit around the Sun.

The planets Saturn and Neptune are orbiting the sun. Therefore the distance between them is changing a lot.
