	Enceladus (Site not responding. Last check: 2007-10-21)
		Enceladus is much too small to be heated by the decay of radioactive material in its interior at present (the heat would have all dissipated long ago).
		Enceladus is locked in a 1:2 resonance with Dione (similar to the situation between Io and Europa).
		Enceladus may be the source of the material in Saturn's tenuous E ring.

	Saturn's Moon Enceladus
		Enceladus [en-SELL-ah-dus] is one of the innermost moons of Saturn.
		It is postulated that Enceladus is heated by a tidal mechanism similar to Jupiter's moon Io.
		Enceladus is one of the coldest places in the Saturn system because its extremely bright surface reflects 80 percent of the sunlight that hits it, so only 20 percent is available to heat the surface.

		Also known as Saturn II (or S2), Enceladus is 310 mi (500 km) in diameter, orbits Saturn at a mean distance of 147,900 mi (238,020 km), and has equal orbital and rotational periods of 1.37 earth days.
		Enceladus has the highest reflectivity (almost 100%) of any body in the solar system.
		The fresh surface suggests relatively recent volcanism, caused perhaps by tidal forces exerted by Saturn and the moon Dione, with which Enceladus forms a satellite pair (that is, they interact gravitationally).

	enceladus
		Enceladus is the eighth of Saturn's known satellites.
		Enceladus is considered by some as the source of the E ring (which can be very faintly seen along Saturn's equatorial plane); icy geysers may be responsible for sustaining the E ring's supply of micrometer-sized particles.
		Enceladus is about 500 kilometers (310 miles) in diameter and has the brightest and whitest surface of any of Saturn's satellites.

		The surface of Enceladus is coated in a thin layer of ice that reflects back nearly all of the sunlight striking it, making it the brightest object in the solar system apart from the Sun.
		Enceladus was thought to be geologically dead, and without geologic activity, there could be no spouting fountains of water and ice on the moon's surface.

		Enceladus shows a variety of surface features and very few impact craters - indicating that it has been an active world even though this tiny moon should have completely cooled off long ago.
		Enceladus could be the result of liquid water geysers or water volcanos.
		Since Enceladus orbits within the outer E ring of Saturn, the moon's surface may be kept snow-bright as it is continuously bombarded with icy ring particles.

	Enceladus Amazes in Two Cassini Swingbys (Site not responding. Last check: 2007-10-21)
		Enceladus was singled out from the rest of Saturn's crowd of inner iceball moons for multiple Cassini flybys.
		The smoothness, relative lack of craters, and linear features on Enceladus all point to a complex geologic history, a long story of volcanic and tectonic activity that will be a fun puzzle for geologists to tease out.
		The boundary between Enceladus' trailing (left) and leading) right hemispheres runs from top to bottom a little to the right of center of this image, which could be one reason.

		Enceladus' orbit is at ~3.95 Rs, between Tethys (at 4.89 Rs) and Mimas (at ~3.08 Rs).
		Enceladus has the brightest surface in the solar system, and imaging suggests much of the icy surface is young (e.g.
		Enceladus has been associated with Saturn's E-ring (suggested sources of the thought-to-be-young E-ring are cryovolcanic droplets, or collisional fragments from small icy bodies in the same orbit, possibly left over from an earlier impact...HST imaging evidence of a transient arc of particles exists (Roddier et al., 1998))

		The red contour encloses the region on Enceladus around the south pole that is the approximate boundary of the warm region as measured by the Composite Infrared Spectrometer (CIRS) instrument on Cassini.
		Evidence is mounting that the atmosphere of Enceladus, first detected by the Cassini Magnetometer instrument, is the result of venting from ground fractures close to the moon's south pole.
		This image was taken during Cassini's close approach to Enceladus on July 14, 2005, with the narrow angle camera from a distance of approximately 103,230 kilometers (64,140 miles) at a Sun-Enceladus-spacecraft, or phase, angle of 50 degrees degrees.

		This means that a strong flow of water must continually replenish the atmosphere, suggesting that Enceladus may be volcanically active or possess steamy geysers.
		The magnetometer measurements were made during Cassini's last two fly-bys of Enceladus, on 17 February and 9 March this year, when the probe got within 500 kilometres of the moon.
		However, since then, scientists have begun to suspect that Enceladus could be the source of Saturn's E ring, made of tiny ice particles.

	SignOnSanDiego.com > News > Science -- Cassini finds Saturn moon Enceladus has an atmosphere, NASA says
		Since Enceladus is a relatively small moon –; 310 miles in diameter – and the gravity it exerts is not enough to hold an atmosphere for very long, there must be a strong continuous source to maintain an atmosphere, NASA said.
		Such a source could be eruptions from volcanoes or geysers, which would put Enceladus in the class of geologically active moons with Jupiter's Io and Neptune's Triton.
		"Enceladus could be Saturn's more benign counterpart to Jupiter's dramatic Io," said Fritz Neubauer, co- investigator for the Cassini magnetometer and a professor at the University of Cologne in Germany.

	Enceladus continues to intrigue scientists
		Following the two distance flybys of Enceladus in February and March this year results from the Magnetometer instrument showed a flowing of the magnetic and plasma field from Saturn towards and then around Enceladus.
		Effectively Enceladus was acting as an obstacle to the flow - indicating the presence of an atmosphere.

		Saturn’s small snow-white moon, Enceladus, has revealed a turbulent past, according to the latest images from NASA’s Cassini spacecraft.

		Cassini passed within 1200 kilometres of Enceladus on Thursday, taking detailed pictures of its surface, resolving details as tiny as 60 metres across.

		Meanwhile, the front page announces that Enceladus has a measurable atmosphere of water vapor, which must be replenished from inside the moon, like the tenuous atmosphere of Io.
		Enceladus could appear snow-white because it is more or less literally covered with snow (or sleet) coming from geysers on the surface.
		The February flyby showed a portion of Enceladus that looked very much like Europa, but the evidence of cryovolcanism is reminiscent of Neptune's moon Triton, and some of the landforms seen on the March flyby turn out to look more like Uranus's peculiar moon Miranda.

		Enceladus is a relatively small moon. The amount of gravity it exerts is not enough to hold an atmosphere very long. Therefore a strong, continuous source is required to maintain the atmosphere.

		Saturn's snow-white moon, Enceladus, is shrouded by a thin water-vapour atmosphere, reveal measurements from the US-European Cassini spacecraft.
		And Enceladus is too tiny to hold onto any atmosphere for long, so astronomers think that more violent processes - such as geysers or ice volcanoes - are replenishing the atmosphere.
