L LAGRANGE POINTS Lagrange points (named for Josef Lagrange, the Italian-French mathematician who discovered them) are a set of five special points that occur between two large objects. At these points, a small orbiting object can orbit at a constant distance from both of the larger masses. This happens because at those five points, the gravitational force of the large objects is exactly equal to the centripetal force required to rotate with the objects. Three of the points are unstable (L , L , and L ) and two are stable(L and L ). Each of the stable Lagrange points forms an equilateral triangle with the two large masses. LAIKA Laika (meaning "barker" in Russian) was the first dog sent into orbit around the Earth. She rode on Sputnik 2, a Russian mission that blasted off on November 3, 1957 (Sputnik 2 was a metal sphere that weighed about 250 pounds = 113 kg). Laika was originally thought to have survived in Earth orbit for four days, dying in space when the batteries to the cabin over-heated. In 2002, it was revealed that Laika died roughly 5 to 7 hours into the flight, from overheating and stress. After orbiting the Earth 2,570 times, Sputnik 2 fell back to Earth on April 14, 1958, burning up during re-entry. Laika was a female mutt who was part Siberian Husky.

Neptune is discovered by Urbain Jean Joseph Le Verrier. Urbain Le Verrier was appointed to teach astronomy at the Ecole Polytechnique in 1837 and abandoned his first subject of chemistry. He worked at the Paris Observatory for most of his life where his drive for efficiency was to made him very unpopular. His main work was in celestial mechanics. 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. Le Verrier was better served by the German astronomer Galle (who found the planet in 1 hour) than Adams was by Airy who gave the task to Challis, the director of the Cambridge Observatory. He observed the planet first but did not recognise it. Arago, who had first suggested that Le Verrier work on this problem, said

LA DECOUVERTE DE NEPTUNE Depuis le début du dix-neuvième siècle, la position des planètes du Système Solaire est connue avec une grande précision. Cependant, l'orbite d' Uranus était imprévisible à long terme. En 1845 en France, l'Académie des Sciences propose deux hypothèses : soit la loi de gravitation n'est pas universelle car elle ne fonctionne pas sur Uranus. soit un corps massif se trouvant relativement près d'Uranus bouleverse l'orbite de cette dernière. Le directeur de l'Observatoire de Paris de l'époque François Arago, demande à Urbain le Verrier d'étudier l'orbite d'Uranus. Ce dernier accepte et émet l'hypothèse d'une huitième planète en se servant de la loi de Titius-Bode. Ainsi le 31 août 1846, Urbain le Verrier explique à l'Académie la position possible de la planète. Etant donné que seul les allemands possèdent des cartes précises du ciel, Le Verrier leur demande de rechercher cette planète. Après 5 jours de recherche, Johann Galle repère la nouvelle planète qui est baptisée Neptune par le Bureau des longitudes de Paris.

Vulcan, 1860-1916, 1971 Francoski matematik Urbain Le Verrier , ki je skupaj z J.C. Adamsom napovedal polo¾aj Neptuna , ¹e preden ga je lahko videl, je na predavanju 2. januarja 1860 naznanil, da je problem opazovanih sprememb pri gibanju Merkurja mo¾no re¹iti z mo¾nostjo obstoja planeta znotraj Merkurja ali pa mogoèe drugega asteroidnega pasu znotraj Merkurjeve orbite. Edini mo¾en naèin opazovanja tega planeta ali asteroidov bi bil, ko/èe bi ti objekti pre¹li Sonèevo ploskev ali pa pri popolnih Sonèevih mrkih. Prof. Wolf na centru za Sonèeve pege v Zurichu je na¹el precej sumljivih "pik" na Soncu , ¹e en astronom pa jih je na¹el ¹e nekaj veè. Skupno dva ducata peg je kazalo, da spadajo v vzorec dveh orbit znotraj Merkurja, ena s periodo 26 dni in druga s periodo 38 dni. Leta 1859 je Le Verrier prejel pismo amaterskega astronoma Lescarbaulta, ki je poroèal, da je 26. marca 1859 videl okroglo èrno pego na Soncu, ki je izgledala, kot da bi planet pre¹el Sonèevo ploskev. Pego je videl eno uro in èetrt, ko se je premaknila za èetrt Sonèevega premera. Lescarbault je ocenil orbitalno inklinacijo med 5,3 in 7,3 stopinjami, dol¾ino seèi¹èa 183 stopinj, njegovo ekscentriènost "ogromno" in njegov prehod èez Sonèevo ploskev 4 ure in 30 minut. Le Verrier je preuèil njegova opazovanja in iz njih izraèunal orbito: perioda 19 dni 7 ur, srednja oddaljenost od Sonca 0,1427 a.e., inklinacijo 12° 10', zahajajoèe seèi¹èe pri 12° 59'. Premer naj bi bil obèutno manj¹i od Merkurja in njegova masa je bila ocenjena na 1/17 Merkurjeve. To je bilo premalo, da bi vplivalo na odstopanja Merkurjeve orbite, toda mogoèe je bil ta najveèji èlan asteroidnega pasu znotraj Merkurja? Le Verrier se je zaljubil v ta planet in ga imenoval

56. Lescarbault The French mathematician urbain le verrier, copredictor with JC Adams of the positionof Neptune before it was seen, in a lecture at 2 Jan 1860 announced that http://www.nexusdomain.org/paranormal/l/lescar.html

Lescarbault - Vulcan , the intra-Mercurial planet, 1860-1916, 1971 T he French mathematician Urbain Le Verrier , co-predictor with J.C. Adams of the position of Neptune before it was seen, in a lecture at 2 Jan 1860 announced that the problem of observed deviations of the motion of Mercury could be solved by assuming an intra-Mercurial planet, or possibly a second asteroid belt inside Mercury's orbit. The only possible way to observe this intra-Mercurial planet or asteroids was if/when they transited the Sun, or during total solar eclipses. Prof. Wolf at the Zurich sunspot data center, found a number of suspicious "dots" on the Sun , and another astronomer found some more. A total of two dozen spots seemed to fit the pattern of two intra-Mercurial orbits, one with a period of 26 days and the other of 38 days. I n 1859, Le Verrier received a letter from the amateur astronomer Lescarbault, who reported having seen a round black spot on the Sun on March 26 1859, looking like a planet transiting the Sun. He had seen the spot one hour and a quarter, when it moved a quarter of the solar diameter. Lescarbault estimated the orbital inclination to between 5.3 and 7.3 degrees, its longitude of node about 183 deg, its eccentricity "enormous", and its transit time across the solar disk 4 hours 30 minutes. Le Verrier investigated this observation, and computed an orbit from it: period 19 days 7 hours, mean distance from Sun 0.1427 a.u., inclination 12# 10', ascending node at 12# 59' The diameter was considerably smaller than Mercury's and its mass was estimated at 1/17 of Mercury's mass. This was too small to account for the deviations of Mercury's orbit, but perhaps this was the largest member of that intra-Mercurial asteroid belt? Le Verrier fell in love with the planet, and named it
