Is Earth bigger than Io?

Is Earth bigger than Io?

Jupiter’s moon Io may be small (roughly the size of Earth’s moon) compared to the planet (more than 1,300 Earths could fit inside Jupiter), but the moon still has a mighty impact on its parent planet. Io’s orbit cuts across Jupiter’s powerful magnetic lines of force, turning Io into an electric generator.

Is Io smaller than Earth’s moon?

A bit larger than Earth’s Moon, Io is the third largest of Jupiter’s moons, and the fifth one in distance from the planet.

How big is Io 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.

Can humans survive 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.

Is Io bigger than Titan?

Differences Between Titan And Io Titan is the bigger of the two with a diameter of 5,150km whilst Io has a diameter of 3,643km. Io orbits Jupiter whilst Titan orbits Saturn.

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.

Why is Io called Io?

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 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?

Geology. 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.

Does Io moon have oxygen?

The team plugged the satellite observations into an emissions model to estimate the atomic oxygen number density. They found more oxygen inside Io’s orbit than previously thought, with a peak density of 80 atoms per cubic centimeter at a distance of 5.7 RJ.

How cold is Io moon?

Its ephemeral, unstable atmosphere is too thin to trap any heat, so Io’s average surface temperature is -202°F. Conversely, some of its lava flows may reach 3,000°F, hotter than anything we see on Earth today.

Is Io a celestial?

Unlike most celestial bodies, Io is a prolate spheroid, pulled out of round by tidal stress from Jupiter’s gravity….Io (moon)

Discovery
Eccentricity	0.0041
Orbital period	1.769137786 d (152853.5047 s, 42.45930686 h)
Average orbital speed	17.334 km/s
Inclination	0.05° (to Jupiter’s equator) 2.213° (to the ecliptic)

Can you see Io with a telescope?

Io’s volcanoes are at times so powerful that they are seen with large telescopes on Earth.

Is Io the only volcanic moon?

Io’s volcanism makes the satellite one of only four known currently volcanically active worlds in the Solar System (the other three being Earth, Saturn’s moon Enceladus, and Neptune’s moon Triton).

Is Io hotter than the sun?

At least 12 different vents on Io spew lava at temperatures greater than2,200 degrees Fahrenheit. One volcanic vent may be as hot as 3,100 degreesFahrenheit – about three times hotter than the hottest sunlit surface ofMercury, the closest planet to the sun.

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.

Can an Io have water?

The water ice is combined with the more abundant sulfur dioxide ice on Io’s surface. Scientists know that Io’s thin atmosphere consists mainly of gaseous sulfur dioxide, but they have been uncertain about the main components of its surface.

How is Io different from Earth?

Thanks to its weird volcanism, Io is a world of freakish extremes. Its ephemeral, unstable atmosphere is too thin to trap any heat, so Io’s average surface temperature is -202°F. Conversely, some of its lava flows may reach 3,000°F, hotter than anything we see on Earth today.

Is Io bigger than Luna?

Geology. 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.

What is bigger than a Earth?

Jupiter, the biggest planet, is more than ten times larger than Earth.

Is Io bigger than Europa?

Ganymede is the largest moon in the Solar System, and is even bigger than the planet Mercury, though only around half as massive. The three inner moons—Io, Europa, and Ganymede—are in a 4:2:1 orbital resonance with each other….Comparative structure.

Moon	rem/day
Io	3600
Europa	540
