	Asteroid Toutatis
		Toutatis is one of the strangest objects in the solar system, with a highly irregular shape and an extraordinarily complex "tumbling" rotation.
		This means that the rotation of Toutatis is a remarkable, well-preserved relic of the collision-related evolution of an asteroid.
		The red, green, and blue axes are the principal axes of inertia; the magenta axis is the angular momentum vector; the yellow axis is the spin vector.

	4179 Toutatis - Wikipedia, the free encyclopedia
		The asteroid 4179 Toutatis (too-ta'-tis) is an Apollo, an Alinda and a Mars-crosser asteroid with a chaotic orbit produced by a 3:1 resonance with the planet Jupiter.
		Radar imagery has shown that Toutatis is a highly irregular body consisting of two distinct "lobes", with maximum widths of about 4.6 km and 2.4 km respectively.
		It is hypothesized that Toutatis formed from two originally separate bodies which coalesced at some point, with the resultant asteroid being compared to a "rubble pile".

	4179 Toutatis
		4179 Toutatis (asteroid 4179) is an Earth-crossing asteroid whose orbit, strongly influenced by Earth's gravity, is chaotic.
		Furthermore, its rotation combines two separate periodic motions that combine to produce a nonperiodic rotation; to someone on the surface of Toutatis the Sun would seem to rise and set in apparently random locations and times at the asteroid's horizon.
		On September 29, 2004 Toutatis will pass within 4 lunar distances of Earth, presenting a good opportunity for observation.

	Toutatis: Almost Too Close for Comfort :: Astrobiology Magazine ::
		Toutatis has a strange rotation --instead of the spinning on a single axis, like the planets and most other asteroids do, Toutatis tumbles so erratically that its orientation with respect to the solar system never repeats.
		Although Toutatis will be in the far southern sky when it is closest to Earth, the asteroid is expected to brighten a few days prior to a 10th magnitude point of light visible from the Northern Hemisphere.
		Toutatis won't be visible to the naked eye, but binoculars should suffice for spotting it in the night sky.

		Toutatis can also refer to the asteroid, 4179 Toutatis.
		He is best known, under the name Toutatis (not recorded in Antiquity), through the Gaulish catchphrase "By Toutatis!", invented for the Asterix comics by Goscinni and Uderzo.
		Teutates was worshipped especially in Gaul and in Roman Britain, altar-stones raised to him having been recovered in the United Kingdom, such as at Cumberland Quarries (1017 [IOM et Mars Toutatis]).

	4179 Toutatis
		Toutatis doesn't have anything that could be called a 'day.' Its rotation is the result of two different types of motion with periods of 5.4 and 7.3 Earth days, that combine in such a way that Toutatis's orientation with respect to the solar system never repeats.
		Radar was used to obtain images in 1992, when Toutatis passed to within 3.6 million kilometers from the Earth.
		On September 29, 2004, Toutatis will pass by Earth at a range of four times the distance between the Earth and the Moon, the closest approach of any known asteroid or cometbetween now and 2027.

	Asteroid 4179 Toutatis
		Asteroid 4179 Toutatis (formerly 1989 AC) was discovered by C. Pollas on January 4, 1989, at Caussols, France, on photographic plates taken on the 0.9-m Schmidt telescope by Alain Maury and Derral Mulholland during astrometric observations of Jupiter's faint satellites.
		Toutatis may have the most chaotic orbit studied to date, a consequence of the asteroid's frequent close approaches to Earth.
		Using the physical model of Toutatis derived from 1992 radar observations (Hudson and Ostro 1995, Science 270, 84-86) to analyze the new data, we obtain refined estimates of the asteroid's orbit, spin state, and surface properties.

		In December 1992, Toutatis came within about 4 million km of Earth enabling radar images to be acquired using the Goldstone Deep Space Communications Complex in California's Mojave desert.
		Numerous surface features on Toutatis, including a pair of large craters, side by side, and a series of three prominent ridges – a type of asteroid mountain range - are presumed to result from a complex history of impacts.
		Whereas the vast majority of asteroids, and all the planets, spin about a single axis, Toutatis tumbles around two axes with different periods, of 5.4 and 7.3 Earth days, that combine in such a way that Toutatis’s orientation with respect to the Solar System never repeats.
