		To be launched in January from Kourou, a space port nestled between the Amazon and the Atlantic in South America's French Guiana, Rosetta's target is a 1.2km-wide ball of ice and dust called Wirtanen, discovered in 1948 by an American astronomer, Carl Wirtanen.
		Wirtanen, he explains, was chosen as Rosetta's target because its relatively small orbit, taking it no further from the sun than the planet Jupiter, makes it one of the few comets within reach of even the world's most-powerful rockets.
		To land gently on Wirtanen, Rosetta will have to gradually sneak up from behind, like the horse-riding outlaws who robbed trains in so many westerns.

	Wirtanen, Comet
		A Jupiter-type comet discovered in 1948 at the Lick Observatory by Carl A. Wirtanen.
		Comet Wirtanen was to have been the target for the Rosetta probe; however, the target comet was changed following a delay in the spacecraft's launch.
		Its orbit takes almost to as close to the Sun as Earth, and almost as far away as Jupiter.

	ALICE: 46P/Wirtanen
		Periodic comet Wirtanen was discovered in 1948 by Carl Wirtanen of Lick Observatory in the course of a stellar proper motion survey.
		Charles Morris (JPL) has compiled individual light curves for each of comet Wirtanen's 1986 and 1991 apparitions, and has also generated a combined light curve for both apparitions.
		The plate on which the discovery was made was taken on 1948 January 15, about a month and a half after the comet had passed perihelion, at which time it was about 16th magnitude.

	Phenomena and Curiosities - To Catch a Comet
		Astronomers targeted Wirtanen, a smallish comet less than a mile in diameter (named after the late Carl Wirtanen, who discovered it in 1948), because it will be in the right place at the right time; eight years from now, it will be nearly as far from the Sun as it gets during its five-and-a-half-year orbit.
		With Wirtanen cruising out by Jupiter’s orbit, scientists predict the detached Rosetta lander, slightly smaller than a washing machine, will have the smoothest possible descent through the coma to the nucleus, where it will conduct analyses for days or longer.
		Thus scientists’ excitement over Rosetta, which aims to catch up with a comet called Wirtanen in November 2011 and land on it within a year—providing the first direct chemical analysis of a comet’s terra firma.

		Wirtanen, for example, was named after Carl Wirtanen of the Lick Observatory in California.
		The most distinctive part of a comet is its dust tail - a trail, up to 10 million km long, of tiny dust particles driven off the nucleus by escaping gases.

	BBC NEWS Science/Nature Where now for Rosetta?
		Comet Wirtanen is off the cards but a handful of similar bodies are being considered as targets.
		By this, he means the wealth of detailed astronomical observations that have been carried out for Wirtanen over the past few years.
		To get to Wirtanen, Rosetta would have had to weave around the inner Solar System, getting a boost from the gravity of Mars and the Earth.

	46P/Wirtanen
		The comet was recovered in 1954 by Carl Wirtanen himself at Lick, very close to the predicted position, although a rather fainter object than in 1948.
		Due to the small number of observations made and the short arc covered the orbit was initially very uncertain and it was a full year before it was recognised as being of short period.
		From then the comet was observed at each return until 1974.

	Imperial College - The Rosetta Mission
		Comet 46 P/Wirtanen was discovered on 15 January 1948 at Lick Observatory by Carl A. Wirtanen.
		Studies will be made of the nucleus of comet Wirtanen and its environment in great detail for a period of nearly two years, the near-nucleus phase starting at a heliocentric distance of about 3.25 AU, with far-observation activities leading ultimately to close observation (from about one km distance).
		The above figure shows the several fly-bys required for Rosetta to achieve its rendezvous with Comet Wirtanen.

	There's A Rock Headed Our Way
		Carl Wirtanen, an astronomer at the Lick Observatory in central California, first spotted this object in May of 1950.
		Conrad Bardwell at the Minor Planet Center quickly determined that the new object and Wirtanen's object, 1950 DA, were one and the same.
		From that conclusion it was possible to find other photos of the asteroid taken during the 1980s.

	The International Rosetta Mission
		Comet 46 P/Wirtanen was discovered on 15 January 1948 by Carl A. Wirtanen.
		As the spacecraft closes with Wirtanen the data it collects will help it to gain a much better picture of the comet’s inherent characteristics, such as position, attitude, size, shape, nucleus angular velocity, gravitational constant and the location of surface landmarks.
		Although Wirtanen is quite small its nucleus is known to be fairly active.

		Its journey to the comet Wirtanen -- named for the man who discovered it, astronomer Carl Wirtanen -- will take eight years, and the craft will swing by planets to pick up gravitational boost to propel it along, the ESA says.
		Eight-year voyage to Comet Wirtanen is to begin with January 2003 liftoff aboard Ariane 5 rocket.
		Officials postponed the launch, originally scheduled for Sunday, after a larger, newer version of the same Ariane-5 rocket veered off course carrying a satellite into orbit in December and had to be destroyed.

	Rosetta
		The comet was discovered by chance by Carl Wirtanen in 1948 on photographic plates at the Lick Observatory in California.
		Although too faint to be seen with the naked eye, Comet Wirtanen made its closest approach to the Sun on 14 March and a fairly close approach to the Earth on 24 March.
		In 1972 and 1984 encounters with the planet Jupiter reduced the size of Comet Wirtanen's orbit, and shortened the interval between its visits to the Sun from 6.65 to 5.5 years.

		Comet Wirtanen is now approaching its farthest point in the orbit, the aphelion, and the coma is therefore expected to be thin, perhaps completely absent.
		Additional technical information: The images of Comet Wirtanen were taken on May 17, 1999, between 06:50 and 09:50 UT with the VLT Test Camera at the KUEYEN telescope (VLT UT2) at the Paranal Observatory (Chile).

		Its journey to Wirtanen - named after its discoverer, astronomer Carl Wirtanen - will take eight years, as the craft needs to swing by planets to pick up gravitational "kicks" to propel it along.
		In 2011, Rosetta will go into orbit around Wirtanen - a ball of ice, matter and dust about one kilometer in width that orbits around the sun every five and a half years.
		The plan at the moment is for an Ariane-5 rocket to catapult the three-ton craft into space from a base in Kourou, French Guiana.

		Until the 1980s, the best map of the universe at large was based on a vast catalog of galaxy counts, around 1 million, published in 1967 by Donald Shane and Carl Wirtanen from the Lick Observatory in California.
		Shane and Wirtanen spent 12 years counting each and every galaxy on the plates, and from their catalog P. James E. Peebles and his colleagues at Princeton University later derived the first major map of the universe, albeit a two-dimensional one.
		Peebles' 1-million-galaxy map was striking: The universe appeared to be filled with a network of knotlike galaxy clusters, filamentary superclusters, and vast regions devoid of galaxies.
