What does it mean if an asteroid in the asteroid belt has a 3 1 orbital resonance with Jupiter?

In the asteroid belt within 3.5 AU from the Sun, the major mean-motion resonances with Jupiter are locations of gaps in the asteroid distribution, the Kirkwood gaps (most notably at the 4:1, 3:1, 5:2, 7:3 and 2:1 resonances). Asteroids have been ejected from these almost empty lanes by repeated perturbations.

What are Jupiter’s 4 largest moons?

This ‘family portrait’ shows a composite of images of Jupiter, including it’s Great Red Spot, and its four largest moons. From top to bottom, the moons are Io, Europa, Ganymede and Callisto.

What is special about Ganymede?

Ganymede is the largest moon in the solar system, and is larger than the planet Mercury. If it were not orbiting as Jupiter’s largest moon, it could be considered a dwarf planet. Ganymede is the only moon in the solar system known to have a substantial magnetosphere.

Is life possible on Ganymede?

Bigger than Mercury and only slightly smaller than Mars, Ganymede may host more water than all of Earth’s oceans in a subterranean ocean about 100 miles/ 160 kilometres below its crust. It’s thought that single-cell microbial life—extremophiles—could exist there.

Is the asteroid belt a failed planet?

A region between Mars and Jupiter became the asteroid belt. Occasionally people wonder whether the belt was made up of the remains of a destroyed planet, or a world that didn’t quite get started. However, according to NASA, the total mass of the belt is less than the moon, far too small to weigh in as a planet.

What is the biggest moon in Jupiter?

Ganymede
Ganymede. Ganymede is the largest satellite in our solar system. It is larger than Mercury and Pluto, and three-quarters the size of Mars. Harpalyke was discovered Nov.

Does Jupiter have 79 moons?

Named Io, Europa, Ganymede and Callisto, these are Jupiter’s biggest moons by far — and they were the first to be discovered. Sheppard’s team just brought the total number of identified Jovian moons (i.e. moons which revolve around Jupiter) up to 79.

What is Ganymede the god of?

Ganymede is the god of homosexual love and desire. He was a divine hero whose homeland was Troy and was the most beautiful of mortals.

How old is Ganymede?

4.503 billion years
Ganymede/Age
Age: Ganymede is about 4.5 billion years old, about the same age as Jupiter. Distance from Jupiter: Ganymede is the seventh moon and third Galilean satellite outward from Jupiter, orbiting at about 665,000 miles (1.070 million kilometers).

Can humans live on Callisto?

Callisto has a very thin atmosphere, is thought to contain an ocean, and is therefore another possible contender for life beyond Earth. However, its distance from Jupiter means it doesn’t experience such a strong gravitational pull, so it’s not as geologically active as the other Galilean moons of Io and Europa.

Do asteroids hit the Sun?

No asteroids have ever been observed to hit the Sun, but that doesn’t mean that they don’t! Asteroids are normally content to stay in the asteroid belt between Mars and Jupiter, but occasionally something nudges them out of their original orbits, and they come careening into the inner solar system.

What kind of rock is Ganymede made of?

Ganymede orbits Jupiter in roughly seven days and is in a 1:2:4 orbital resonance with the moons Europa and Io, respectively. Ganymede is composed of approximately equal amounts of silicate rock and water ice.

How often does the orbit of Ganymede change?

The ranges of change are 0.0009–0.0022 and 0.05–0.32°, respectively. These orbital variations cause the axial tilt (the angle between rotational and orbital axes) to vary between 0 and 0.33°. Ganymede participates in orbital resonances with Europa and Io: for every orbit of Ganymede, Europa orbits twice and Io orbits four times.

Which is Ganymede OCT system does Thorlabs use?

Thorlabs offers four complete, preconfigured Ganymede OCT systems, each of which is fully compatible with all Ganymede Series OCT components. The GAN210C1 configuration features a center wavelength of 930 nm and is designed for general-purpose imaging applications.

Why is there a magnetic field on Ganymede?

The cause of the light terrain’s disrupted geology is not fully known, but was likely the result of tectonic activity due to tidal heating. Ganymede’s magnetic field is probably created by convection within its liquid iron core.
