MORE INFORMATION AND FACTS ABOUT NEPTUNE

When scientific discoveries are made there is often a debate (sometimes heated) as to who deserves credit. The discovery of Neptune is one such example. Shortly after the discovery of the planet Uranus in 1781, scientists noticed that its orbit had significant fluctuations that were not expected. To solve this mystery, they proposed the existence of another planet whose gravitational field would account for such orbital variances.

In 1845, the English astronomer John Couch Adams completed his calculations as to the position of this unknown planet. Although he submitted his findings to the Royal Society (the leading English scientific organization), his work was met with little interest. However, a year later the French astronomer Jean Joseph Le Verrier made known his calculations that were strikingly similar to those of Adams. As a result of the two men’s independent estimates being so close, the scientific community took notice and began its search for the planet in the region of the sky Adams and Le Verrier had predicted. On September 23, 1846, the German astronomer Johann Gall observed the new planet near to where Adam’s calculations had forecasted and even closer to those of Le Verrier.

Le Verrier was initially given credit for the discovery. As a result, an international dispute arose, with one faction championing Adams and the other Le Verrier. This conflict, however, was not shared between the two men themselves. Eventually, the campaign for each side cooled, and both men were given credit.

Until the Voyager 2 spacecraft fly-by in 1989, little was known about Neptune. This mission provided new information about Neptune’s rings, number of moons, atmosphere and rotation. Additionally, Voyager 2 discovered significant features of the moon Triton. There are no official planetary missions scheduled to Neptune in the near future.
