Hydrostatic equilibrium is the balance between the inward force of gravity and the outward pressure gradient in a fluid, like in a star or planet. This equilibrium prevents further collapse or expansion by ensuring that the pressure within the fluid supports the weight of the overlying material. In stars, this balance between gravity and pressure helps maintain their stable size and shape.
What else can I help you with?
Is Pluto in hydrostatic equilibrium?
Yes, Pluto has been determined to be in hydrostatic equilibrium. Planets must orbit the sun (the first criterion for a planet), and must also be in hydrostatic equilibrium (which Pluto is). Pluto fails the third "planetary entrance test" set by the IAU in that it has not cleared its orbit of debris. A link can be found below to check facts and learn more.
What does the phrase hydrostatic equilibrium in the sun refers to?
Hydrostatic equilibrium in the Sun refers to the balance between the inward gravitational force and the outward pressure force generated by nuclear fusion. This balance maintains the Sun's stable structure and allows it to maintain its size and shape over time.
What is the difference between self-gravitation and hydrostatic equilibrium of celestial bodies?
Hydrostatic equilibrium basically means the object has a round shape - spherical if it doesn't spin quickly, in the form of an ellipsoid if it does.Self-gravitation is the mechanism that causes it. It means that all of the parts of the object attract one another.
Why is Mimas not considered to be in hydrostatic equilibrium?
I think it is. Take a look at some pictures of Mimas; it looks pretty round to me.
The maintenance of hydrostatic equilibrium of the Earth's crust is called?
Isostasy. This is the balance between the weight of the Earth's crust and the buoyant force exerted by the mantle beneath it, ensuring that the crust remains in a state of equilibrium.
What are the two forces that are in equilibrium in a star?
Hydrostatic and Equilibrium

When a star's inward gravity and outward pressure are balance the star is said to be?
Hydrostatic equilibrium occurs when compression due to gravity is balanced by a pressure gradient which creates a pressure gradient force in the opposite direction. The balance of these two forces is known as the hydrostatic balance.
Why is Mars round?
Basically it is because of gravity. The technical explanation is called the " principle of hydrostatic equilibrium ".

What is the difference between hydraulic and hydrostatic?
hydraulics uses the principle of hydrostatic pressure to work

What effects does stellar equilibrium have on stars?
The properties of a main-sequence star can be understood by considering the various physical processes occurring in the interior. First is the hydrostatic balance, also called hydrostatic equilibrium. This determines the density structure of the star as the internal pressure gradient balances against the force of gravity.
A balance between the weight of a layer in a star and the internal energy pressure that supports it is?
achieved through the process of hydrostatic equilibrium. This balance helps maintain the stability and structure of the star by ensuring that the inward gravitational force is counteracted by the outward pressure force generated by the internal energy of the star.
When the outward force due to fusion and radiation balances with the inward force of gravity a star is said to be experiencing?
hydrostatic equilibrium.
What is one force that is responsible for maintaining the balance of a star during the main sequence stage?
Hydrostatic equilibrium [See related question]
