Titan is the largest moon of Saturn and the second-largest natural satellite in the Solar System. It is the only moon known to have a dense atmosphere, and the only known body in space, other than Earth, where clear evidence of stable bodies of surface liquid has been found.

Ganymede

Size. Ganymede is the largest and most massive moon in the Solar System. Its diameter of 5,268 km is 0.41 times that of Earth, 0.77 times that of Mars, 1.02 times that of Saturn’s Titan (Solar System’s second largest moon), 1.08 times Mercury’s, 1.09 times Callisto’s, 1.45 times Io’s and 1.51 times the Moon’s.

Although phonons—the smallest units of the vibrational energy that makes up sound waves—are not matter, they can be considered particles the way photons are particles of light.

In particle physics, preons are point particles, conceived of as sub-components of quarks and leptons. The word was coined by Jogesh Pati and Abdus Salam, in 1974.

In 2012, scientists confirmed the detection of the long-sought Higgs boson, also known by its nickname the “God particle,” at the Large Hadron Collider (LHC), the most powerful particle accelerator on the planet. This is because Higgs particles attract each other at high energies.

Thus, protons and neutrons are no more indivisible than atoms are; indeed, they contain still smaller particles, which are called quarks. Quarks are as small as or smaller than physicists can measure. Similar experiments show that electrons too are smaller than it is possible to measure.

A gluon (/ˈɡluːɒn/) is an elementary particle that acts as the exchange particle (or gauge boson) for the strong force between quarks. In layman’s terms, they “glue” quarks together, forming hadrons such as protons and neutrons.

Scientists’ current understanding is that quarks and gluons are indivisible—they cannot be broken down into smaller components. Because of this, quarks and gluons are bound inside composite particles. The only way to separate these particles is to create a state of matter known as quark-gluon plasma.

Atoms, in turn, are made up of electrons orbiting a nucleus of protons and neutrons, which themselves are made up of quarks. String theory suggests that electrons and quarks are actually minuscule vibrating loops of energy. one unified force in such extreme conditions.

The strong force binds quarks together in clusters to make more-familiar subatomic particles, such as protons and neutrons. It also holds together the atomic nucleus and underlies interactions between all particles containing quarks.
