north star
The absolute magnitude of a star depends on the size and temperature; a large cooler star can generate as much light as a small very hot star.
A white dwarf star can be very hot due to residual heat from its earlier evolution, but it may not be very bright because of its small size. This is because the heat energy is spread over a smaller surface area compared to larger, brighter stars.
The obvious reason is that the specific star has bigger density compared with the Sun. For example, that star could be a "white dwarf star". A white dwarf mostly contains "electron degenerate matter", which is very dense. A white dwarf is a small dense star.
Technically a dead star is when a star no longer undergoes nuclear fusion. Depending on the mass of the original star this will either be a white dwarf, neutron star or black hole. These are called stellar remnants.
Both white dwarfs and neutron stars match the description. Neutron stars are smaller, hotter, and denser.
stars that are dim probably have both a small mass and a larger radius.
dwarf star
The difference between the death of a small star and a massive star is what the become afterwards. A small star will typically become a red dwarf while a large star will become a neutron star or a black hole.

a very strange but intesting star :p
For very small angles, the focal length of a concave mirror is approximately half of the radius of curvature of the mirror. This is known as the mirror equation and holds true for small angles under the paraxial approximation.
Radio telescopes detect stars known as 'Pulsars'. They're very small and also known as neutron stars.
Its simple friends, the space doesn't have mass or its negligible in sense but the black hole is the result of the life ending of a star and thus its mass is also very very high and its radius is also very very low. Black holes are very small in size having very large mass. so as we know gravity is directly proportional to the mass but it is indirectly proportional to the radius and i think you got the answer
Stars and the moon are very very far away. the closest star is over 20 light years away. and, the moon is very very small compared to a star. so a star couldent enter the moon, the moon would enter a star.
An older star that has become small is called a white dwarf. White dwarfs are the remnants of low to medium mass stars that have exhausted their nuclear fuel and collapsed to a very dense state. They are very hot and small compared to their original size as a main sequence star.
