A star is primarily made up of hydrogen and helium gases. These gases undergo nuclear fusion in the star's core, creating intense heat and light. Other elements such as carbon, oxygen, and iron are also present in smaller amounts.
A solar system.
No, a neutron star is not 100% neutrons. The outer portion of a neutron star may consist of a crust of iron nuclei and electrons.
Planetary Nebula are the outer layers of a star that are lost when the star changes from a red giant to a white dwarf. A star is a luminous globe of gas producing its own heat and light by nuclear reactions (nuclear fusion). They are born from nebulae and consist mostly of hydrogen and helium gas.
Two stars in a binary star system are most likely 4 light years apart. Binary star systems are common in the universe and consist of two stars that orbit around a common center of mass.
Tectonic plate consist of lithospheric mantle overlain by crustal
A solar system.
It consist of dust, gas, always one star, and possibly planets--like ours!
Sea star (starfish), sea cucumber
It really depends on the star. But most stars consist mainly of hydrogen-1.
No, a neutron star is not 100% neutrons. The outer portion of a neutron star may consist of a crust of iron nuclei and electrons.
a moon and a star and it consist of two colors green and a strip of white
I believe it's Orion

Yes, nebula are responsible for star formation, so ultimately that's exactly what they do.
Universe, Cluster, Galaxy, Star, Planet NB: Some stars are smaller than planets.
By definition, a binary star system has two stars in it.
A star is made up primarily of hydrogen atoms. Hydrogen atoms consist of one proton and one electron. So, a star contains a very large number of hydrogen particles corresponding to the total mass and volume of the star, with each hydrogen atom having one proton.
