COMETAS, PLANETAS e GALÁXIAS A incrível história do planeta descoberto matematicamente. John Adams, outro astrônomo azarado. Newton, no final, estava muito certo. Desde que Urano foi descoberto por Herschel, sua órbita foi calculada levando em conta a atração gravitacional do Sol e a influência dos demais planetas, principalmente Saturno e Júpiter. Após algumas décadas notou-se que a órbita calculada com as leis de Newton desviava-se ligeiramente da órbita observada pelos astrônomos. A confiança na teoria newtoneana era tão grande que a maioria dos cientistas começou a suspeitar que outro planeta, ainda desconhecido e mais distante, estava perturbando um pouco a trajetória de Urano. Vários cientistas se dedicaram à tarefa de tentar localizar esse novo planeta. Usando as Leis de Newton e os valores da órbita desviada de Urano, talvez fosse possível, matematicamente , calcular a posição do planeta desconhecido. Só que este tipo de cálculo é extremamente elaborado e, naquele tempo, tinha de ser feito à mão. Só dois heróis conseguiram ir até o fim sem desanimar e terminaram seus cálculos quase ao mesmo tempo. Um deles, o inglês John Adams, chegou primeiro ao resultado e enviou uma carta aos astrônomos do observatório de Londres. Mas, Adams era um estudante de apenas 25 anos e os medalhões ingleses deixaram as previsões do jovem calculista na gaveta. Já o outro era o francês Urbain Le Verrier, astrônomo de prestígio. Ele enviou sua carta ao observatório de Berlim e seu pedido foi atendido imediatamente. Na mesma noite, 23 de Setembro de 1846, o astrônomo alemão Johann Galle apontou seu telescópio para o local do céu indicado por Le Verrier, e de fato, lá estava um ponto luminoso que não constava nos mapas celestes: um novo planeta. Com a notícia do grande feito os ingleses resolveram olhar para o céu na posição indicada por Adams e também viram o planeta previsto matematicamente pelo jovem calculista.

Adams, Airy and the Discovery of Neptune in 1846 by Allan Chapman Soon after Neptune was discovered in Berlin, in September 1846, using Le Verrier's Computed position, a furore broke out in Britain about the priority of John Couch Adams. Though Adams's claim had not been advanced until October 1846, when even the English astronomers were still speaking of "Le Verrier's Planet", it came to be realised that Adams had already arrived at a computed position for the Uranus-disturbing planet by the autumn of 1845. Adams, via a letter of introduction from Professor Challis in Cambridge, had applied to Professor George Biddell Airy, the Astronomer Royal for some kind of assistance, though he failed to secure an interview with Airy, and nothing further happened - until the New Planet was discovered in Berlin, nearly a year later. Popular interpretations of this incident place a great deal of responsibility upon Airy, for not having taken the initiative to secure a British discovery. Yet this is unjust, and several key factors must be born in mind: It was not the job of the Astronomer Royal to undertake searches.

The Neptune File: Planet Detectives and the Discovery of Worlds Unseen. Tom Standage. Penguin Books Ltd. 2000. ISBN 0-713-99472-X.  pp200.  £12.99. ISBN 0-713-99472-X John Couch Adams “a lot has been written about the Neptune affair but until now nothing so even-handed as Tom Standage’s new book” Tom Standage is science correspondent for the Economist. He is the author of The Victorian Internet and has written for Wired, the Guardian, the Indipendent and the Daily Telegraph. He is married and lives in Greenwich. Penguin Books: The Neptune File As said, a lot has been written about the Neptune affair but until now nothing so even-handed as Tom Standage’s new book. There is something to be said for a well-informed science journalist writing an unbiased account of a rather specialized subject for what I assume is a general readership.  His Neptune story is well presented and the scientific-political intricacies of the time easily followed. Tom Standage hits the nail squarely on the head in describing an unfortunate episode that could have gone in favour of UK astronomy, but didn’t.  It was, nevertheless, a supreme example of computational dexterity on both sides of the Channel and Standage describes the situation with paramount skill.  Couch Adams wouldn’t say ‘boo’ to a goose but Le Verrier didn’t hide his light behind anybody’s bushel. Both calculated the position of the unseen planet with remarkable accuracy but were beholden to the telescopists to find it for them.

TSE Current Issue The Soapbox Archive Submission Guidelines ... Contact Us The Phantom Planet Vulcan Tony Sakalauskas On March 26, 1859, a French medical doctor and amateur astronomer named Lescarbault claimed to have observed a planet closer to the sun than Mercury. He called it Vulcan, after the Roman god of fire. He calculated the planet’s movements and sent the information onto Urbain Le Verrier, France’s most famous astronomer. Le Verrier had already noticed that Mercury deviated from its orbit. A gravitational pull from Vulcan would fit in nicely with what he was looking for. Le Verrier checked out other reports and found out that other astronomers had also seen a small black disk against the background of the sun. They all knew that it couldn’t be a sunspot, because sunspots travel more slowly. Le Verrier decided to pay the doctor a visit. When Le Verrier examined Lescarbault’s telescope, he found that it was of very poor quality and that it gave distorted images. Yet, the astronomer still believed that the doctor discovered a new addition to the solar system. From calculations made with this inferior equipment Le Verrier came to the conclusion that Vulcan was 13 million miles (21 million kilometers) from the sun and that it took twenty days to complete its orbit. Most astronomers couldn’t find the planet, so most astronomers didn’t believe it existed. Le Verrier said that it would be seen crossing the sun in March or April of 1860; it wasn’t. The emminent astronomer concluded that the transit happened at night when the sun was not visible. But the sun was visible on the other side of the Earth.

71. THE SURMISE OF VULCAN In 1845 a French astronomer by the name of urbain le verrier (18111877), attemptedto resolve this problem by proposing the existence of a planet lying inside http://www.ldolphin.org/unruh/vulcan.html

PLANETARY PAPERS, NO. 1 THE SURMISE OF VULCAN The Story of the Hypothetical Intra-Mercurian Planet by J. Timothy Unruh Since the invention of the telescope in the early 1600's several major planets have been discovered in the remote regions of interplanetary space beyond the realm of Saturn, namely Uranus, Neptune, and Pluto. The search for more such planets has continued to some extent even to this day. In the last century, although, a flurry of serious speculations were circulating among world class astronomers about the possible existence of a planet not at the outer reaches of the Solar system but at the inner region of the planetary family, inside the orbit of Mercury. This suspected planet precipitated the exploration of the Sun's immediate neighborhood resulting in a number of cases where observers have reported such a body. At one time it was believed that there was a planet even closer to the Sun than Mercury based on unexplained orbital perturbances observed in the latter caused by the gravitational influence of a supposed heretofore undiscovered object hidden in the Solar glare. It was already known that the point of planet Mercury's orbit closest to the Sun was progressively 38 seconds per century greater than would be predicted on the basis of Newtonian mechanics. In 1845 a French astronomer by the name of Urbain Le Verrier (1811-1877), attempted to resolve this problem by proposing the existence of a planet lying inside the orbit of Mercury which he named Vulcan, after the Roman god of fire and the blacksmith of the gods. Subsequently he began to look for it. Previously he had made extensive mathematical studies on the motions and variations in planetary orbits and became an expert on the subject in his own

Urbain Jean Joseph Le Verrier: Le Verrier was a very successful man. On October 1846, Times carried the headlines " Le Verrier's planet found ". Working independently of Adams, Le Verrier calculated the position of Neptune from irregularities in Uranus's orbit. As one of his colleagues said "He discovered a star with the tip of his pen, without any instruments other than the strength of his calculations alone". In the eyes of all impartial men, this discovery will remain one of the most magnificent triumphs of theoretical astronomy, one of the glories of the Academie and one of the most beautiful distinctions of our country. Le Verrier discovered something in the motion of Mercury in 1855. He spent much effort searching for asteroids inside the orbit of Mercury in an attempt to prove his theory. But he died before he got the chance
