How far is Io from Earth?
628.3 million km
Io/Distance to Earth
Can you see Io from Earth?
Io zips around Jupiter in 1.8 days, whereas our moon circles Earth every 28 days. Bottom line: You can see Jupiter’s four largest moons – Io, Europa, Ganymede and Callisto, known as the Galilean satellites – with your own eyes with the help of binoculars or a small telescope.
Can humans live on Io?
This means Io is a land of both fire and ice. Io is generally considered a poor candidate for life because of all the radiation Jupiter blasts it with. In addition, no organic molecules have been detected on its surface, and it has only an extremely thin atmosphere devoid of detectable water vapor.
Is Io a rocky planet?
Jupiter’s rocky moon Io is the most volcanically active world in the solar system, with hundreds of volcanoes, some erupting lava fountains dozens of miles (or kilometers) high.
How cold is Io?
Temperature: Io’s surface temperature averages about minus 202 degrees Fahrenheit (minus 130 Celsius), resulting in the formation of sulfur dioxide snowfields. But Io’s volcanoes can reach 3,000 F (1,649 C). Io is often referred to as a celestial body of fire and ice.

What is the largest moon of Jupiter?
Ganymede
Ganymede is the largest satellite in our solar system. It is larger than Mercury and Pluto, and three-quarters the size of Mars. Callisto is the most heavily cratered object in our solar system.
What is the smallest Galilean moon?
Europa
Moving outward from Jupiter is Europa. While slightly smaller than Earth’s moon, it is still one of the largest bodies in the solar system but the smallest of the Galilean satellites.
Why is Io so hot?
So, why is Io so darn hot? The likeliest cause is tidal forces – the pulling and tugging of the moon by the gravity of Jupiter. Io orbits at only 421,000 km from Jupiter, making a full orbit in ~1.76 days. This distortion causes heat through friction, thus causing Io to stay hot (and partially molten).

Where is Io located in relation to Jupiter?
Io orbits Jupiter at a distance of 421,700 km (262,000 mi) from Jupiter’s center and 350,000 km (217,000 mi) from its cloudtops. It is the innermost of the Galilean satellites of Jupiter, its orbit lying between those of Thebe and Europa. Including Jupiter’s inner satellites, Io is the fifth moon out from Jupiter.
How big is Io the moon of Jupiter?
Io is a Moon that orbits round the planet Jupiter. It is also know by other designations, Io. Its mass is estimated/calculated at being 89,319,379,731,108,900,000,000 kg. Its density has been calculated at being 3.528. Its volume is 25319064907.
Is it possible for Io to have a moon?
Io even has lakes of molten silicate lava on its surface. Io’s very thin atmosphere is primarily sulfur dioxide, which on Earth is sometimes used to preserve dried food. Io has no known moons of its own, but it is possible for moons to have moons. Io has no known rings, but it does create a gaseous torus of material along its orbit around Jupiter.
What kind of atmosphere does the moon Io have?
Sulfur dioxide is the primary constituent of a thin atmosphere on Io. It has no water to speak of, unlike the other, colder Galilean moons. Data from the Galileo spacecraft indicates that an iron core may form Io’s center, thus giving Io its own magnetic field.
