Why does io move so fast?

Io's remarkable activity is the result of a tug-of-war between Jupiter's powerful gravity and smaller but precisely timed pulls from two neighboring moons that orbit farther from Jupiter – Europa

Europa

Europa /jʊˈroʊpə/ ( listen), or Jupiter II, is the smallest of the four Galilean moons orbiting Jupiter, and the sixth-closest to the planet of all the 92 known moons of Jupiter. It is also the sixth-largest moon in the Solar System.

and Ganymede.

Why is Io so special?

The moon Io is the most volcanically active world in the solar system. Io even has lakes of molten silicate lava on its surface.

Why is Io so smooth?

Except for the locations of the active volcanoes, the surface of Io is extremely smooth. Apparently the volcanic action is so intense and continuous that flow from the volcanoes smooths out any irregularities and erases impact craters.

How fast does Io orbit?

Io fast facts

Its average orbital distance is about 262,000 miles (422,000 km). Io takes 1.77 Earth-days to orbit Jupiter. Io is tidally locked, so the same side always faces Jupiter.

Why does Io not crash into Jupiter?

Io's orbit, keeping it at more or less a cozy 262,000 miles (422,000 kilometers) from Jupiter, cuts across the planet's powerful magnetic lines of force, thus turning Io into a electric generator.

Why Does Io Have So Many Volcanoes?

Can we land on Io?

A day on Io is about 42.5 hrs or about 1.77 Earth days long. All in all, there's no way you can use Io's atmosphere for aerobraking to land and no need for a heat shield.

Could Io be terraformed?

Io is an inhospitable moon of Jupiter. Terraforming will prove extremely challenging but colonization of Io would be relatively easy using the geothermal energy to create an electromagnetic field so we could protect the colony from the radiation belt of Jupiter.

Why is Io so yellow?

Io's colors derive from sulfur and molten silicate rock. The unusual surface of Io is kept very young by its system of active volcanoes. The intense tidal gravity of Jupiter stretches Io and damps wobbles caused by Jupiter's other Galilean moons.

Is Io losing mass?

Yes, Io is losing mass because of its volcanic activity, but not as much as you'd think. Several of Io's volcanoes spray gas and particles high above the surface, but most of that material falls back down to the surface, creating colorful and bright ring deposits.

How is Io so hot?

Its orbit bends to pull it closer to Jupiter. Io is again squished like a football. All this bending causes heat to build up inside Io. Io gets so hot inside that some of the material inside melts and boils and tries to escape any way it can.

What would Jupiter look like from Io?

From the surface of Io, Jupiter would appear an amazing 36 times larger than the full moon (from earth). Jupiter's diameter is ~140,000 Km. Io's distance from Jupiter is ~420,000 Km. So if you held a basketball about three times its diameter away, it would look roughly as big.

Could humans walk on Io?

Other than on the four gas giants you cannot walk in present-day-like spacesuits on Venus (due to the extreme heat) and Jovian moon Io (due to the extreme radiation and also some heat) either.

Is Io cold or hot?

Io is one of the hottest and most active moons in the solar system, but its volcanoes aren't losing as much heat as predicted.

How hot is the lava on Io?

Io was found to have at least 12 active volcanoes erupting lava at temperatures over 1200 degrees Celsius. Scientists believe that lava at one of the sites reaches a temperature of over 1700 degrees Celsius.

How big is Io to Earth?

Io is 3642.6 km, or 0.28 Earths, wide. It only has a mass of about 1.4% of the mass of Earth. It is a similar size to our Moon (but a lot more exciting!).

What would Io smell like?

The distinctive yellow-orange color of the surface comes from sulfur (although Io looks like a pizza, it would smell like a rotten egg).

Why does Io look like a pizza?

Description. Io has often been described as looking like a pizza covered with melted cheese, tomato sauce and olives. The reason for this distinct surface is its vast number of active volcanoes. There are hundreds of volcanoes scattered over the surface of the moon, which is a bit larger than Earth's Moon.

Why is Io uninhabitable?

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.

Does Jupiter love Io?

In Greek myths, Io was the daughter of Inachus, the first king of Argos, and she was a priestess of Hera. Zeus (Jupiter was his Roman name), the king of the gods and Hera's husband, fell in love with her, as a result of which she suffered disturbing dreams.

Which planet is easiest to terraform?

While Venus, Earth, Mars, and even the Moon have been studied in relation to the subject, Mars is usually considered to be the most likely candidate for terraforming. Much study has been done concerning the possibility of heating the planet and altering its atmosphere, and NASA has even hosted debates on the subject.

Could life live on Io?

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.

How many Earths can fit in Io?

With a mean radius of 1821.6 ± 0.5 km, and a mass of 8.93 ×10²² kg, it's equivalent in size to 0.286 Earths and 0.015 times as massive. Io orbits Jupiter at an average distance (semi-major axis) of 421,700 km (0.002819 AU).
