Io moon meaning

Io is named after a maiden who was loved by Zeus. In the Greek myth, Zeus turned her into a heifer in an attempt to hide her from his jealous wife, Hera. Io was discovered by Galileo Galilei and Simon Marius in 1610 and is one of the four Galilean satellites.

What is the moon Io named after?

Io, also called Jupiter I, innermost of the four large moons (Galilean satellites) discovered around Jupiter by the Italian astronomer Galileo in 1610. It was probably also discovered independently that same year by the German astronomer Simon Marius, who named it after Io of Greek mythology.

What is special about Io moon?

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

Which moon is Io?

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.

Can Io moon support life?

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.

Why is Io moon 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 does Io stand for?

Input/output (I/O or IO): In computer science, the abbreviation I/O or IO stands for input/output, i.e., the communication of information systems such as computers with the outside world.

Is Io the hottest moon?

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. Volcanologist and Eruptions blogger Erik Klemetti reports on a new study of the Jovian volcanic moon.

Is Io bigger than Luna?

Io is slightly larger than Earth's Moon. It has a mean radius of 1,821.3 km (1,131.7 mi) (about 5% greater than the Moon's) and a mass of 8.9319×10²² kg (about 21% greater than the Moon's). It is a slight ellipsoid in shape, with its longest axis directed toward Jupiter.

Is Io moon hot or cold?

Temperature: Io's surface temperature averages about minus 202 degrees Fahrenheit (minus 130 degrees Celsius), resulting in the formation of sulfur dioxide snowfields. But Io's volcanoes can reach 3,000 degrees F (1,649 degrees C). Io is often referred to as a celestial body of fire and ice.

Why is Io so radioactive?

Io is one of the four Galilean moons of planet Jupiter. It is the hottest moon in the solar system, recording up to 2,600°F around its 400 volcanoes, hotter than Earth's volcanoes. Due to its proximity to Jupiter, it receives 3,600 rem of radiation a day (compared to 0.001 rem per day on Earth).

Does Jupiter love Io?

Io was a priestess of the Roman goddess Juno. Juno was the jealous wife of Jupiter, the king of the gods. Jupiter was very unfaithful. When Jupiter fell in love with Io, he changed himself into the shape of a dark cloud to hide himself from his jealous wife Juno.

What color is the moon Io?

Most of Io's surface has pastel colors, punctuated by black, brown, green, orange, and red units near the active volcanic centers.

Can you see Io from Earth?

Bottom line: You can see Jupiter's moons – Io, Europa, Ganymede and Callisto, known as the Galilean satellites – with your own eyes with the help of binoculars or a small telescope.

Is Io the youngest moon?

Indeed, we now know that Io has the youngest surface in the Solar System. Present estimates are that it is so active geologically that its surface is completely redone on a timescale of about a million years---a twinkling of the eye on geological timescales.

Is the moon called Io or Lo?

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.

Why is the moon Io 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.

Why does Jupiter's moon 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.

What is the Io lander called?

Pioneer 11 provided the first spacecraft image of Io, a 357 km (222 mi) per pixel frame (D7) over Io's north polar region taken from a distance of 470,000 km (290,000 mi).

Is Io a hot moon?

Is Io the youngest moon?

Can you see Io from Earth?

Bottom line: You can see Jupiter's moons – Io, Europa, Ganymede and Callisto, known as the Galilean satellites – with your own eyes with the help of binoculars or a small telescope.

Is Io moon hot or cold?

Why was Io named Io?

It is just slightly larger than Earth's moon. Io is named after a maiden who was loved by Zeus. In the Greek myth, Zeus turned her into a heifer in an attempt to hide her from his jealous wife, Hera. Io was discovered by Galileo Galilei and Simon Marius in 1610 and is one of the four Galilean satellites.

Is Io moon radioactive?

Io's surface radiation level is 3,600 rem per day — five times a lethal human dose. The radiation is strong enough to damage surface materials, darkening them, especially at Io's poles.
