The source of gravity on the Moon is its mass. Gravity is a force that attracts objects with mass towards one another, and the amount of gravity depends on the mass of an object. The Moon's gravity is about 1/6th of Earth's gravity due to its smaller mass.
If we consider classical physics (Newtonian explanations) the source is unaffected. The strength of the gravitational pull decreases as the second power of the distance.
Gravity is strongest near very massive objects, such as planets and stars. The strength of gravity also depends on the distance between two objects; the closer they are, the stronger the gravitational force.
When billions of stars are found in the same region of the universe, it is typically referred to as a galaxy. Galaxies are vast systems composed of stars, gas, dust, and dark matter, bound together by gravity. Our own galaxy, the Milky Way, is just one of billions of galaxies in the observable universe.
An open cluster is a group of stars that are loosely bound together by gravity. These clusters typically contain hundreds to thousands of stars and are found in the disk of a galaxy, like our Milky Way. Open clusters are younger than globular clusters and often form from the same molecular cloud.
I am not at all sure what you mean; the "source of gravity" of each star is its own mass, i.e., the star itself.
Bot stars and planets are spherical objects that are held together by gravity.

They are the corpses of some super giants. They are very small, but have the same gravity and mass as their old self.
By the gravity compression of interstellar gases - same as all other stars.
Gravity will attract 2 or more object with or without the presence of an electric source/field.
If we consider classical physics (Newtonian explanations) the source is unaffected. The strength of the gravitational pull decreases as the second power of the distance.
They are attracted to one another by gravity, which is not affected by electrical charge. Gravity is an attractive force that occurs between all objects with mass. You don't have positive and negative masses that attract and repel. The greater the mass, the greater the attraction. Second, the stars do not all have the same mass. The masses of stars vary considerably.
Gravity is strongest near very massive objects, such as planets and stars. The strength of gravity also depends on the distance between two objects; the closer they are, the stronger the gravitational force.
This calculation is based on the fact that we can measure the lights emitted during an explosion of a supernova in the Universe .The red light spectrum measured during this explosion , among others , indicate that the galaxies are accelerating away from each other at a higher speed . But the big question is why ? Why is the Universe expanding and with that we mean why are the bodies within the Universe moving faster and faster towards the unknown . The answer this question we have to use two methods. First , the effect of gravity within the Universe on all bodies that is in the space like Galaxies and by using a common sense approach towards this complex material . The expansion of the Universe is thanks to the force of gravity , the same gravity we experience on earth but at a much bigger scale. So big that we as humans can not understand how this is possible or where it is originated . Based on my theory, I can inform that the galaxies are accelerating faster and faster as they approach the what I call , the gravity source. The farther the galaxies are from us ( the Earth ) , the faster they are moving away from us. Why ? Because these galaxies are approaching the gravity source. Some call this gravity source, dark matter ( they use this name because they don't know what it is ) . A galaxies does not move on their own energy in the Universe, no...the galaxies use the energy of this gravity source as the fuel to spin and move them into the space of the Universe. All galaxies are moving to the same target. It is not so that one galaxy goes left and the other one goes right. No, in the Universe the law of gravity rules and it works in a constant and organized way .In our solar system the gravity source is our Sun. Thanks to the Sun our planets can rotate around the Sun due to the sun's gravity energy . It is this same type of gravity energy that makes our galaxies spin and move . Again , the farther the galaxies are, the faster they are accelerating because they are attracted by the gravity field of this gravity source. There is no other theory that can proof this one to be wrong. It is the only logical explanation why the Universe is expanding . So, the next question is what is this gravity source that is responsible for the expansion of the Universe made of ? Where is it located within our Universe ? I will answer this in my next answer it session . Greg Falconi
That is called a star cluster. Star clusters are groups of stars that are bound together by gravity and formed from the same parent molecular cloud.
on very very clear nights yes starts are almost the same size as the sun.
