The egg-shape of Io reported by Pickering was the result of measuring only the bright equatorial band of Io, and mistaking the dark poles for background space. [21] Later telescopic observations confirmed Io's distinct reddish-brown polar regions and yellow-white equatorial band. [ 26 ]
Io (/ ˈ aɪ. oʊ /), or Jupiter I, is the innermost and second-smallest of the four Galilean moons of the planet Jupiter.Slightly larger than Earth's moon, Io is the fourth-largest moon in the Solar System, has the highest density of any moon, the strongest surface gravity of any moon, and the lowest amount of water by atomic ratio of any known astronomical object in the Solar System.
Volcanism on Io, a moon of Jupiter, is represented by the presence of volcanoes, volcanic pits and lava flows on the surface. Io's volcanic activity was discovered in 1979 by Linda Morabito, an imaging scientist working on Voyager 1. [1] Observations of Io by passing spacecraft and Earth-based astronomers have revealed more than 150 active ...
Space colonization is the process of establishing human settlements beyond Earth for prestige, commercial or strategic benefit, [3] in contrast to space exploration for scientific benefit. Colonialism in this sense is multi-dimensional, including the exploitation of labor, resources and rights.
Orbital and rotational energy are dissipated as heat in the crust of the moon. Io has a similar mass and size as the Moon, but Io is the most geologically active body in the Solar System. This is caused by the heating mechanism of Io. The major heating source of Earth and the Moon is radioactive heating, but the heating source on Io is tidal ...

The atmosphere of Io is the extremely thin blanket of gases surrounding Jupiter's third largest moon Io. The atmosphere is primarily composed of sulfur dioxide ( SO 2 ), along with sulfur monoxide ( SO ), sodium chloride ( NaCl ), and monoatomic sulfur and oxygen . [ 1 ]
ɒ ˈ s ɔː l iː /), the highest mountain of Jupiter's moon Io, is one of the tallest mountains in the Solar System. It is located just northwest of the volcano Pele, in the Boösaule Montes. The official name of the mountain range was given in honor of the cave in Egypt where Io gave birth to Epaphus, and approved by the IAU in 1985.
