No, a planet does not collapse because gravity isn't strong enough to provide enough pressure to crush a planet.
You might make a planet heavier and heavier as to increase its gravity but at some point the pressure in the planet's core will be high enough to support nuclear fusion and the planet will have changed into a star. At that point radiative pressure also begins to fight gravity.
What else can I help you with?
Is an atmosphere possible without a magnetosphere Could a planet-sized Faraday cage act as an artificial magnetosphere?
Yes. Mars has a thin atmosphere despite not having a magnetosphere. A planet-sized Faraday cage would probably be impossible as it would likely collapse under its own gravity.
How can you say that the earth is a planet?
A planet - is defined as an object that has its own gravity, and is in orbit around a sun.
Planet in a sentence?
Mars is known as the Red Planet. When aliens speak of Earth they call it the Blue Planet.
Stars are formed from interstellar clouds because of?
Because of gravity. Only gravity can pull large clouds together with enough force to overcome gas pressure.
What difference of a star and a planet?
A star is a luminous ball of plasma held together by its own gravity and produce energy through thermonuclear fusion. A planet is a body orbiting a star massive enough to be rounded by its own gravity but not massive enough to conduct fusion.

Yes. Mars has a thin atmosphere despite not having a magnetosphere. A planet-sized Faraday cage would probably be impossible as it would likely collapse under its own gravity.
What are black holes essentially?
Black holes are regions in space where gravity is so strong that nothing, not even light, can escape from them. They are formed when massive stars collapse under their own gravity.
What needs to occur for a star to be born?
A clump of matter must collapse under the attraction of its own gravity. The collapse must heat the matter up to form a plasma which undergoes thermonuclear fusion - of hydrogen into helium.
Are black holes solid objects?
No, black holes are not solid objects. They are regions in space where gravity is so strong that nothing, not even light, can escape from them. They are formed when massive stars collapse under their own gravity.
Why isn't the world flat?
Gravity has a preference for large ball shaped objects. In fact, being spherical under the force of its own gravity is part of the current definition of 'planet'.
What is the diameter in miles that a planet has to be in order to be considered a planet?
To qualify as a planet, a body has to be approximately spherical (achieving hydrostatic equilibrium under its own gravity), it has to orbit the sun and it has to have cleared its orbit of all other objects - so that at that distance from the sun, there are no other sizable bodies. Theres no set size, but to achieve an approximately spherical shape under its own gravity, a planet would have to be at least around 500-600 miles in diameter.
What two factors cause a nebula to develop into a star?
The two main factors that cause a nebula to develop into a star are gravity and heat. Gravity pulls the gas and dust in the nebula together, causing it to collapse under its own gravity. As the collapse continues, the temperature and pressure in the core of the collapsing nebula increase, eventually reaching a point where nuclear fusion ignites, and a star is born.
Where does a star get enough energy to stop the collapse that would be caused by its own gravity?
radiation pressure
How can you say that the earth is a planet?
A planet - is defined as an object that has its own gravity, and is in orbit around a sun.
How stars create?
Clouds of gas will collapse, under certain circumstances, due to their own gravity. These will eventually become stars. This process is described in more detail in the Wikipedia article on "Protostars".
Explain why the sun does not collapse under the force of its own gravity?
Stars do not collapse because the inward force of gravity is balanced by the pressure generated by fusion. When stars die they do collapse. The cores of low to medium mass stars collapse to form white dwarfs. Further collapse is prevented y electron degeneracy pressure. More massive stars leave behind neutron stars, in which gravity is balanced by neutron degeneracy pressure. In the most massive stars, once fusion stops producing energy there is nothing to stop the collapse and the core becomes a black hole.
Is there a relationship between the distance a planet is from the sun and its surface gravity?
Yes, there is a relationship between a planet's distance from the sun and its surface gravity. The closer a planet is to the sun, the stronger the gravitational pull from the sun, which can affect the planet's own gravity. However, other factors, such as a planet's mass and composition, also play a significant role in determining its surface gravity.
