Can a planet collapse on itself?

Answer 1: That is an excellent question, and the short answer is that you’re right, the Earth doesn’t collapse in on itself because it isn’t massive enough.

Why earth does not collapse under its own gravity?

Force of gravity is not enough to overcome bonding force between atoms in matter of the Earth. That is why the Earth is not collapsing. Forces always occur in a pair. Every action must have a reaction.

Which planet has a rocky surface?

The planets Mercury, Venus, Earth, and Mars, are called terrestrial because they have a compact, rocky surface like Earth’s terra firma. The terrestrial planets are the four innermost planets in the solar system.

Can you see ton 618 from Earth?

The light originating from the quasar is estimated to be 10.8 billion years old. Due to the brilliance of the central quasar, the surrounding galaxy is outshined by it and hence is not visible from Earth.

How large can rocky planets get?

Rocky planets can become extremely large. Just consider Chthonian planets, former gas giants whose atmospheres were blown off and whose cores are left barren. COROT-7b is one such planet — it’s definitely above five Earth masses, possibly as much as ten Earth masses.

Is rocky planets the smallest?

Rocky planets are smaller than gas planets, but are made of heavier materials. There are four rocky planets in our Solar System: Mercury, Venus, Earth, and Mars.

What is the transition from rocky planets to gas giants like?

The problem is the transition from “rocky” to “gas giant” is not well defined. From this article: “The largest “terrestrial” planet is generally considered the one before you get too thick of an atmosphere, which happens at about 5-10 Earth masses (something like 2 Earth radii).

What is the maximum possible size for a rocky planet?

It can be reasonably estimated that the maximum size for a rocky planet is three or four times earth size. $\\begingroup$ The best way to calculate this is to find what size planet at that orbit will hold Hydrogen and Helium and Methane. If it does, it will be a gas giant, otherwise rocky.

What causes an object to collapse under its own gravity?

All objects with mass have the force of gravity pulling the mass towards the object’s centre of gravity. Unless there is a balancing force the object will “collapse under it’s own gravity” (distinct from collapsing as a result of some other force, such as a supernova explosion).

Can a planet be large enough to create a black hole?

There’s the possibility of the planet being large enough to cause the genesis of a black hole. If we go with increasing the size of the Earth to the Sun’s radius, it would have a mass of 3.9 solar masses, and the pressure at its core would be 8.75*10^11 atm.
