The Planet Neptune

Neptune was discovered on September 23, 1846 by Johann Gottfried Galle and Louis d'Arrest, an astronomy student, through mathmetical predictions made by Urbain Jean Joseph le Verrier. Neptune is the outermost planet, and has eight moons. Also, Neptune has an equilatorial diameter of 49,500 kilometers meaning that it could hold 60 Earths. In addition, on Neptune one day is 16 hours and 6.7 minutes and it makes a complete orbit around the Sun every 165 years.

Two-thirds of Neptune is composed of molten rock, water, liquid ammonia, and methane. Nonetheless methane is the gas that gives Neptune its blue color.

Also, common to Juipter, Neptune has several dark spots. Neptune's largest spot is called the Great Dark Spot and is approximately the size of the Earth. This spot is a pinwheel shape with feather-like clouds filling the separation between the light and dark blue regions. There is also a small spot idealized to be a storm in the atmosphere. In addition, in 1994 a new dark spot was discovered, and no more have been discovered recently. These dark spots, however, at times seem to disappear.

Neptune also has long bright clouds in the upper atmosphere. These clouds resemble Earth's cirrus clouds. Also, these clouds cast a shadow on cloud deeks underneath.

Out of all the planets Neptune has been found to have the strongest winds. These winds tend to move westward, antagonistically to the planets rotation. Interestingly enough, these winds seem to be the strongest around the Great Darkshot.

The plane Neptune also consists of rings. It has four rings that are diminutive and faint. The rings are composed of dust particles supposed to have been created by minute meteroites smashing into the moons of Neptune. Also, these rings appear to be arcs from ground based telescopes. However, from satellite Voyger2 they turn out to be bright clumps in the rings.

Also, Neptune has a magnetic field similar to Uranus'and is highly tilted from its rotation axis. This tilt off sets approximately, .55 radii from Neptune physical center. Scientists think the dramatic orientation of the two planets magnetic field distinctive of flows in the inner area of the planet and not resulting from its tilt.

Neptune, in conclusion, is a unique planet. It has dark spots similar to Juipter, rings that are unique, and a magnetic field that is somewhat like Uranus'. Also, Neptune has a mystifying blue color, and a strnage tilt. Although Neptune is not as commonly well known, such as Juipter, it still has a difference that makes it just as important.
