gravitational force
One good example are the fact that when you stand up, there is a force ... known as your "weight" ... that holds you down to the floor. That force is nothing but the force of mutual gravitational attraction between you and the earth.
The sun is a million miles wide ball of nuclear furnace, in which the outward force of the fusion heat balances the protracted force of its own gravity. Its output of light and heat remain uniformly constant, as well as its ability to maintain a powerful magnetic force seen within storms and patterns on its surface. The most obvious pattern of variation is the 11-year sunspot cycle. However, even this cyclical variation isn't constant; some cycles are very active, while other cycles seem quite below the average.The massive gravitational force and extreme magnetic force of the sun is held in a state of relative equilibrium by the vast amounts of energy generated by nuclear fusion within the core. The sun operates in an balanced quid pro quod state between the inward gravitational contraction and outward pressure generated by nuclear fusion.When the hydrogen fuel begins to be exhausted, helium "ash" collecting in the core will temporarily overcome the gravitational contraction and the sun will expand into a red giant. This is expected to begin fairly gradually some time between three and four billion years from now.

The sun is being hold by gravity, in the sun there are like magnets which creates our solar system, the suns extreme gravity is what holds everything but the magnet fields is what makes us move around the sun but the core of the earth is what makes us rotate. The suns extreme Gravity is what basically holds its gasses.
Gravitational force formed the earth and holds all things on its surface - including us!
the gravitational force holds its atmosphere together
The mutual force of gravitational attraction between the sun and the earth.
WHAT HOLDS THE EARTH IN ITS ORBIT REVOLVING AROUND THE SUN?In fact the Earth's orbit is a sort of equilibrium. The Earth's revolutions around the Sun provides it with centripetal force. A force that wants to eject it out of its orbit. That same force that wants to eject you out of your car when you are in a tight bend.However (and fortunately) there exist a strong gravitational force (attracting force) between the Sun and the Earth. It happens that the centripetal force ejecting the Earth is equal and hence balances the gravitational force pulling it towards the earth. As a result the Earth continues its motion around the Sun, undisturbed.As a conclusion, I'll say that what holds the Earth around the Sun it a result of 2 forces acting opposite to each other, namely the centripetal force pulling it away from the Sun and the gravitational force pulling it towards the Sun.

That's the mutual gravitational attraction between the sun and the earth.
The gravitational force between the Earth and the atmosphere holds the atmosphere close, just like it holds you close to the Earth. (ground)
It's the mutual forces of gravitational attraction between the Earth and each object.

A single body doesn't have a gravitational force. The force only shows up when there are two bodies. It pulls both of them toward each other, and they both feel the same force. The force between you and the earth is called your "weight", and it holds you down. The force between the earth and the moon is what keeps the moon in its orbit.
