Unlike most satellites in the outer Solar System which have a thick coating of iceIo is primarily composed of silicate rock surrounding a molten iron or iron sulfide core. Io Jupiter I. Callisto is the fourth and last Galilean moon, and is the second largest of the four, and at Please edit this page to improve it. They also reveal significant alteration of the surface. Callisto is surrounded by an extremely thin atmosphere composed of carbon dioxide [5] and probably molecular oxygen.

  • 4) the inner moons have densities higher than outer moons (implies that such that the moons formed near Jupiter have less of the volatile elements such as. Mass ( kg), Radius (km), Mean density (kg/m3), Visual geometric albedo. Galilean Satellites.

    Io (JI),Europa (JII). The Galilean satellites of Jupiter, discovered in by Galileo, are the most.

    the inner satellites, Io and Europa, had rock-like densities, similar to the Moon's. of rock-forming elements may hydrate in two distinct stages (see Chapter IV),​.
    With over active volcanoes, Io is the most geologically active object in the Solar System. The rotation of the three inner moons, in contrast, indicates differentiation of their interiors with denser matter at the core and lighter matter above.

    They have apparent magnitudes between 4.

    In Ganymede a thick and solid ice crust then formed. Retrieved Life in such an ocean could possibly be similar to microbial life on Earth in the deep ocean. The color of the markings, reddish-brown, is theorized to be caused by sulfur, but scientists cannot confirm that, because no data collection devices have been sent to Europa.

    Science : — It is one of the smoothest objects in the solar system, with a layer of water surrounding the mantle of the planet, thought to be kilometers thick.

    They were discovered soon after Galileo made improvements to his telescope around January It has a tenuous atmosphere composed primarily of oxygen.

    The ~ major satellites of Jupiter - the so called Galilean satellites - and the innermost satellite of from Jupiter and subdivided, according to the orbital elements, into two distinct groups.

    10 lo is a Mercury-sized object with lunar density. Present structure and key elements responsible for the evolution are now relatively well Three of the galilean moons should possess a liquid water ocean.

    Galilean Satellites

    The Galilean moons are the four moons of Jupiter discovered by Galileo Galilei. Retrieved With over active volcanoes, Io is the most geologically active object in the Solar System. So far, there is no evidence that life exists on Europa, but the likely presence of liquid water has spurred calls to send a probe there.

    The rotation of the three inner moons, in contrast, indicates differentiation of their interiors with denser matter at the core and lighter matter above. Retrieved Callisto is the fourth and last Galilean moon, and is the second largest of the four, and at The prominent markings that criss-cross the moon seem to be mainly albedo featureswhich emphasize low topography.

    This page has been nominated for cleanup for the following reason: the rest of this article was copied from Wikipedia and needs a bit more editing. The apparent youth and smoothness of the surface have led to the hypothesis that a water ocean exists beneath it, which could conceivably serve as an abode for extraterrestrial life.

    1. The main difficulty in observing the moons from Earth is their proximity to Jupiter since they are obscured by its brightness.

    2. California State University, Fresno. All this evidence suggests that the nearer a moon is to Jupiter the hotter its interior.

    3. They have apparent magnitudes between 4.

    4. Although not proven, recent data from the Galileo orbiter indicate that Io might have its own magnetic field. However, this is less likely than on nearby Europa.
