A star is made of gas What forces hold a star together?

Answer 1

That is still a mystery. Obviously, they are held together by gravitation. Each star attracts each other star, and you might say that the combined force of these attractions keeps the galaxy together. But the known matter in our galaxy - and in other galaxies - isn't strong enough to account for the fast rotation a galaxy has. There must be about 5-10 times more matter, compared with known matter, in something invisible - commonly known as "dark matter". This mysterious dark matter can be noticed through its gravitational attraction, but it can't be seen directly.

Answer 2

A star is held together by two main forces: gravity, which pulls matter inward, and radiation pressure, which pushes matter outward. Gravity tries to collapse the star, while radiation pressure from nuclear fusion in its core creates an outward force that balances gravity, maintaining the star's equilibrium.

Answer 3

The stars are not "held" fixed in the sky, but are so far away that their movement is imperceptible. The whole of the universe is a moving, expanding, seemingly infinite array of stars, galaxies, and huge groups of galaxies, in a cosmic expanse of which Earth is only a tiny part. (But, as far as we know to date, we are the only consciousnesses here to witness it.)

Answer 4

Stars are held together by gravity.

A star is basically a body that produces energy at the same rate as it contains it.

Answer 5

The forces of gravity of a star helps to hold it together.

Answer 6

The mass of a star holds it together. The gravity of the mass atomically draws it toward the middle of the star.

Answer 7

Yes. Actually, the gases in the stars are considered to be in a "fourth state of matter", called plasma. The difference is that in a plasma, many of the atoms are ionized.

Answer 8

Insufficient momentum to escape.

Answer 9

Gravity Caused by nuclear fusion

Answer 10
