As the name suggests, neutron stars are actually composed of neutrons. When there is a sufficiently strong gravitational field, atoms (or superheated plasma consisting of fragments of atoms) collapse, and the electrons and the protons combine to form neutrons. Only neutrons are left.
Neutrons are created through various nuclear reactions, such as in nuclear fission or fusion processes. In these reactions, atoms may split or combine, resulting in the release of neutrons. Neutrons can also be generated in particle accelerators by bombarding target materials with high-energy particles.
It depends what you mean by "made". Neutrons pervade nature in all elements except hydrogen and were possibly "made" in nature in the early moments after the big bang from quarks and gluons coalescing once the temperature dropped enough for this to happen. If you mean made as in laboratory situations and for nuclear reaction purposes, a neutron heavy substance such as Uranium readily sheds neutrons as the neutrons contribute to the instability of the heavy uranium atom. So they are not really made, but "found" in a sense.
Nucleons are made up from quarks. Protons and neutrons each contain three quarks. We haven't been able to split a proton or neutron apart so its more of an idea of quarks based on evidence
There are several types of quark we name them on characteristics they give to a particle. Such as up, down, top, bottom, spin, charm and strange.
Nucleons (otherwise known as baryons when outside the atom) contain only up and down quarks
Proton: UUD
Neutron: UDD
antimatter is made up of antiquarks and follow a similar pattern to how matter is made up
Along with protons, neutrons make up the nucleus, held together by the strong force. The neutron is a baryon and is considered to be composed of two down quarks and one up quark.
A free neutron will decay with a half-life of about 10.3 minutes but it is stable if combined into a nucleus. The decay of the neutron involves the weak interaction as indicated in the Feynman diagram to the right. This fact is important in models of the early universe. The neutron is about 0.2% more massive than a proton, which translates to an energy difference of 1.29 MeV.
The decay of the neutron is associated with a quark transformation in which a down quark is converted to an up by the weak interaction . The average lifetime of 10.3 min/0.693 = 14.9 minutes is surprisingly long for a particle decay that yields 1.29 MeV of energy. You could say that this decay is steeply "downhill" in energy and would be expected to proceed rapidly. It is possible for a proton to be transformed into a neutron, but you have to supply 1.29 MeV of energy to reach the threshold for that transformation. In the very early stages of the big bang when the thermal energy was much greater than 1.29 MeV, we surmise that the transformation between protons and neutrons was proceeding freely in both directions so that there was an essentially equal population of protons and neutrons.
The composition of a neutron is said to be one up quark and two down quarks.
Free neutrons decay, giving off particles, which are a proton, and electron, and an electron antineutrino.
Neutrons are made of Quarks. More specifically, 1 "up quark" and 2 "down quarks."

Is quark bigger or neutron?
Neutron is bigger than a quark. A neutron is a composite particle made up of three quarks, while a quark is a fundamental particle that makes up protons and neutrons.
Is a electron smaller than a neutron?
Yes, an electron is smaller than a neutron. An electron is a fundamental particle and has a much smaller mass than a neutron, which is made up of quarks.
What charge is a neutron?
A neutron has no charge, as it is electrically neutral.
How can a neutron have a magnetic moment when it has no charge?
A neutron has a magnetic moment due to the intrinsic magnetic properties of its constituent particles, quarks. Quarks carry electric charges and intrinsic magnetic moments, contributing to the overall magnetic moment of the neutron, even though the neutron as a whole is electrically neutral.
What is the abbreviation of neutron?
The abbreviation for neutron is "n".
What is the neutron made of?
Neutrons are made of quarks (3 per neutron).
These are the tiny particles that make up neutrons and protons in an atoms nucleus?
Both a neutron and a proton are made up of 3 quarks.Both a neutron and a proton are made up of 3 quarks.Both a neutron and a proton are made up of 3 quarks.Both a neutron and a proton are made up of 3 quarks.
What is the made of neutron in fungi?
food
What is the necleus made of?
It is made up of protons and neutron particles.
What is a neutron in an atom made up of?
A neutron can be split up into 2 down quarks and an up quark.
Is quark bigger or neutron?
Neutron is bigger than a quark. A neutron is a composite particle made up of three quarks, while a quark is a fundamental particle that makes up protons and neutrons.
What is an atom mad of?
its made from protons,neutron and electrons
Can a neutron star become a nebula?
No, a neutron star can't become a nebula. A neutron star is not made of atomic matter, has less mass than a nebula, and has no mechanism by which to expand.
What is a star made up of neutrons?
We think that they are made of free particles and the cores may be composed of neutron degenerate matter. But we don't know for sure and it's fairly complicated. You can look up neutron stars on wikipedia for a better answer.
How many films have there been made of jimmy neutron?
One : "The Adventures of Jimmy Neutron: Boy Genius" is the only one I know of .
Which is bigger a quark or a neutron?
Since neutrons are made up of three quarks, it's very safe to say the neutron is bigger.
What are magnetars made of?
Magnetars are a special type of neutron star.
