Density and pressure Neutron stars have overall densities of 3.7×1017 to 5.9×1017 kg/m3 (2.6×1014 to 4.1×1014 times the density of the Sun), which is comparable to the approximate density of an atomic nucleus of 3×1017 kg/m3.

A star is a small (relatively) ball of plasma that is generally sufficiently gravitationally compacted to initiate nuclear fusion in its core. A galaxy is about 10 billion or more of the above, all gravitationally bound to each other.

Density is a physical property of matter that expresses a relationship of mass to volume. The more mass an object contains in a given space, the more dense it is.

Density and pressure A neutron star is so dense that one teaspoon (5 milliliters) of its material would have a mass over 5.5×1012 kg, about 900 times the mass of the Great Pyramid of Giza.

A typical white dwarf is about as massive as the Sun, yet only slightly bigger than the Earth. This makes white dwarfs one of the densest forms of matter, surpassed only by neutron stars and black holes. Medium mass stars, like our Sun, live by fusing the hydrogen within their cores into helium.

Proton is composed of gluons and three quarks, two up and one down, precisely. Neutrons are also composed of gluons and three quarks but their combination is different, one up and two down quarks. Up quarks is lighter than a down quark. Therefore, neutron is a bit heavier than a proton.

At the modest temperatures and pressures of Earth's surface, the densest known material is the metallic element osmium, which packs 22 grams into 1 cubic centimetre, or more than 100 grams into a teaspoonful. Even osmium is full of fluff, however, in the form of electron clouds that separate the dense atomic nuclei.

A white dwarf is very dense: its mass is comparable to that of the Sun, while its volume is comparable to that of Earth. A white dwarf's faint luminosity comes from the emission of stored thermal energy; no fusion takes place in a white dwarf.

When a star dies, it spent all of its energy and then collapses. Their difference lies on their parent star. ... When a dying star has a mass which is 1.4 to 3 times that of the sun, it will form a neutron star. Stars with a mass greater than thrice the sun's mass, black hole is formed.

The density at the center of a black hole is infinite (it's a famous "singularity", which leads to difficulties in modern cosmology). On Earth, densities range from 10-4 g/cm3 for light gases to 0.001 g/cm3 for aerogels and up to the heaviest substance, osmium, with a density of 22.61 g/cm3.

Up quarks is lighter than a down quark. Therefore, neutron is a bit heavier than a proton. Neutrons are slightly heavier than protos because they are actually protons with an electron embedded which cancels out the charge.

The density of Earth is 5.52 g/cm3, while the density of Saturn is 0.687 g/cm3. In other words, Earth is 8 times as dense as Saturn. Another region where Saturn and Earth are similar is gravity. Of course, Saturn has much more mass than Earth, but it's spread out over a larger area.

As adjectives the difference between dense and heavy is that dense is having relatively high density while heavy is (of a physical object) having great weight or heavy can be having the heaves.

Neutron stars are significantly more dense than white dwarfs which themselves are significantly more dense than normal matter on earth. ... -Nova is a smaller explosion out of hydrogen that leaves white dwarfs intact. -X-ray burster is a neutron star that has x-ray bursts. How are nova formed?

A neutron is made of 3 quarks, one up quark, and 2 down quarks and many many "intermediate particles" called gluons which carry the interaction between the quarks. These gluons are exchanged very often, so the quarks feel each of other.
