	Tempel 1 - Wikipedia, the free encyclopedia
		It was subsequently observed in 1873 and in 1879.
		Tempel 1 was re-discovered in the 1960s after American astronomer Brian G. Marsden performed precise calculations of the comet's orbit, taking into account Jupiter's perturbations.
		On July 4, 2005 at 05:52 UTC (01:52 EDT), Tempel 1 was impacted by the NASA Deep Impact probe.

	Ernst Wilhelm Leberecht Tempel - Wikipedia, the free encyclopedia
		Ernst Wilhelm Leberecht Tempel (December 4, 1821 – March 16, 1889) was a German astronomer who worked in Marseille until the outbreak of the Franco-Prussian War in 1870, then later moved to Italy.
		He was a prolific discoverer of comets, discovering or co-discovering 21 in all, including Comet 55P/Tempel-Tuttle, now known to be the parent body of the Leonid meteor shower, and 9P/Tempel, the target of the NASA probe Deep Impact in 2005.
		The asteroid 3808 Tempel is named in his honour.

		Ernst Wilhelm Leberecht Tempel was born on December 4, 1821, in Nieder-Kunersdorf, in the kingdom of Saxony.
		In March of 1860 Tempel relocated to Marseilles and obtained employment at the Observatory that was then under the direction of Valz.
		In 1874 Tempel left Milan to accept the post of Assistant in charge of the Arcetri Observatory, which was connected with the Reale Instituto di studi superiori of Florence.

		An artistic free spirit, Ernst Tempel was born on December 4, 1821 in Saxony, one of 12 children.
		However, after Donati's death in 1873, support for the Observatory declined and Tempel was forced to subsist on a meager salary with no funds to complete or maintain the observatory's two refracting telescopes.
		Ernst identified with Tempel's difficult life and sympathized with the troubles he encountered in finding suitable work in Germany because he lacked a formal education.

	Artists interpret nature in new Ackland show
		German-born Ernst (1891-1976) was a pioneer of the surrealist movement in early 20th century art; Phillippine-born Ossorio (1916-1990) reflected surrealism’s influence in his work.
		Ernst’s vehicle was called frottage: rubbing pieces of wood, seashells, leaves or other natural material on paper or canvas to obtain images.
		Researching the collection, Matilsky identified parallels between Ernst and Ossorio, and the idea for the exhibition was born.

	Wilhelm Tempel
		But Tempel continued to show himself an indefatigable observer, and as he had only his 4-inch refractor he was naturally induced to remain faithful to the field of work in which he had first been successful – that of comet-seeking.
		Among the eight comets which he found while at Marseilles, [1] the first one of 1866 attracted great attention from its connection with the November meteors, while the second one of 1867 was found to belong to the interesting class of periodic comets of short period.
		The years which Tempel had spent in comet-seeking had caused him to take a great interest in nebulae, and, notwithstanding all the obstacles with which he had to contend at Arcetri, he resolved to apply himself to observations of these objects.

		Tempel 1 is named for Ernst Wilhelm Leberecht Tempel, who first spotted it in 1867 while searching for comets in the sky over Marseilles, France.
		Tempel 1 is surrounded by a coma, the 50,000-mile-wide gas cloud generated by the comet as the solar wind blasts its surface.
		Tempel 1 is moving at 66,880 mph, faster than the spacecraft, which is just poking along at 48,990 mph.

	Comet Tempel 1
		The comet was then 9th magnitude and described by Tempel as having an apparent diameter of 4 to 5 arcmin across.
		Gautier's predictions enabled Tempel to recover the comet on April 25, 1879.
		With an orbital eccentricity of 0.5, Tempel 1's orbit lies between the orbits of Mars and Jupiter.

		The images are a reminder that Tempel 1's icy nucleus, roughly the size of central Paris, is dynamic and volatile.
		In 1881, comet Tempel 1 passed 0.55 AU from Jupiter.
		Tempel 1 has been moving closer to the Sun, and perhaps the increasing heat opened up a crack in the comet's dark, crusty surface.

	Tempel, (Ernst) Wilhelm (Leberecht) (1821-1889)
		In 1860 he went to Marseilles to work at the Observatory, in 1871 he joined Schiaparelli at Brera Observatory in Milan, and in 1874 he went to Arcetri Observatory.
		Tempel discovered the Merope Nebula (NGC 1435) in the Pleiades in October 1859.
		Later he discovered many more nebulous objects: 156 NGC entries were credited to him, of which at least 123 belong to real deep sky objects.

		Tempel 1's nucleus, half the size of Manhattan but obscured by dust and gas streaming from it, did not come into clear view until about 9 p.m.
		Comet 9P, better known as Tempel 1, was discovered April 3, 1867, by German astronomer Ernst Wilhelm Leberecht Tempel while he was searching for comets from an observatory in Marseilles, France.
		Tempel 1 is called a short-period comet because it circles the sun in a much smaller orbit than other comets whose orbits take them to the far edge of the solar system.

		Comet Tempel 1, moving at the Deep Impact spacecraft at 23,000 miles per hour, collided with the impactor probe as successfully planned.
		Comet Tempel 1 was discovered in France in 1867 by Ernst Wilhelm Leberecht Tempel, who discovered several comets in his lifetime, some of which are associated with meteor showers.
		Due to the faintness of Comet Tempel 1, and its low altitude in the Arizona sky on Sunday night at 11PM (when the probe will impact), the comet, even brightened, may continue to be impossible to find visually in amateur telescopes from light polluted city locations.

	Spaceflight Now \| Delta Launch Report \| Comets and Deep Impact's encounter with Tempel 1
		A comet or asteroid is credited as the likely source of the impact that changed Earth's climate, wiped out the dinosaurs and gave rise to the age of mammals 65 million years ago.
		Tempel 1 is a short-period comet - meaning that it moves about the Sun in an elliptic orbit between the planets Mars and Jupiter.
		In other words, the changes in the motion of comet Tempel 1 caused by Deep Impact are completely negligible when compared to the comet's orbital changes as it passes by Jupiter.

	NASA set for a crash with comet - The Boston Globe - Boston.com - Nation - News
		Tempel 1 hasn't caused any mass hysteria, although it has prompted a lawsuit against NASA from a Russian astrologer who claims the crash will disrupt the balance of the universe -- and destroy some of her personal memories.
		NASA officials say the comet, half the size of Manhattan, won't budge from its orbit because of the hit, equating the force of the probe's impact to a mosquito running into a 767 airliner.
		Tempel 1, named for Ernst Wilhelm Leberecht Tempel, the astronomer who discovered it in 1867, doesn't have any special properties that make it a particularly good target.

	Amazing Space: Starwitness news
		Amateur astronomer Ernst Wilhelm Leberecht Tempel of Marseilles, France, discovered comet 9P/Tempel 1 in 1867 while using a telescope to search for comets.
		It is named "Tempel 1" because it was the first comet spotted by Tempel.
		Astronomers are eager to learn whether Tempel 1, which has depleted much of its outer layers of gas and ice, has kept some gas and ice in its interior.

		The larger "flyby" spacecraft carries a smaller "impactor" spacecraft to Tempel 1 and releases it into the comet's path for a planned collision.
		In January 2005, a Delta II rocket launches the combined Deep Impact spacecraft which leaves Earth's orbit and is directed toward the comet.
		While the flyby spacecraft and impactor do their jobs, pro-fessional and amateur astronomers at large and small telescopes on Earth observe the impact and its aftermath, and results are broadcast over the Internet.

		Tempel 1 was just above the southwestern horizion for observers in the extreme western United States, but it was not immediately known how many amateurs might have been able to detect the sudden brightening that signaled the impactor's crash.
		Tempel 1 originated in the Kuiper Belt, a broad flattened disk of icy debris extending from the orbit of Neptune to well beyond Pluto.
		Tempel 1 was chosen for the Deep Impact mission because it is reachable in the mission timeframe, the nucleus is fairly large and thus relatively easy to hit and its orbit allows the impact to occur on the sunlit side.
