Stars

Stars are balls of luminous plasma, held together by gravity. They can be seen twinkling overhead from our planet each night. They are enjoyable to look at, but also have been used as navigation tools for centuries.

What gas is the sun burning?

User Avatar

Asked by Wiki User

The SUN does NOT BURN gas.

It is a FUSION of hydrogen atoms into helium atoms.

What is a white and red dwarf star?

User Avatar

Asked by Wiki User

A White Dwarf star starts as a small to intermediate size star,

like our Sun is currently. That eventually becomes a red giant

star. Eventually that blows off everything but the hot very dense

core of "electron degenerate matter". What is left is a hot ball of

mainly carbon and oxygen that will eventually cool and dim and turn

into a black dwarf star.

A white dwarf has a second chance of life and death in a close

binary star system, where the white dwarf draws mass from the

companion star. Once the mass of the white dwarf reaches the

Chandrasekhar limit of approximately 1.38 solar masses or roughly

140% of the mass of our Sun, the core can no longer hold the

gravitational pressure and a Type 1a Supernova may occur.

A Red Dwarf star is a " Main Sequence " star, but with very low

mass and

luminosity. You need a telescope to see one. However, they make

up about

80% of all stars and they have very long lifetimes.

Which objects motion causes eclipses of the sun?

User Avatar

Asked by Wiki User

The solar eclipse occurs when the moon is in between the sun and earth .

So because the sun is the center of the solar system and is not supposed to move in it the earth and moon's movement causes the eclipse

Are stars fixed in space?

Asked by Wiki User

NO!!!! THey move. However, because they are so far away , we do not readily observe any movement amongstr the stars. Objects nearer toi Earth Like the Sun and planets, moons, etc., are seen to move because they7 are nearer .

How are the stars and the sun the same?

User Avatar

Asked by Wiki User

all stars are not all the same (blue giants, red giants, red dwarfs), however the sun is a star. it just appears bigger in the sky because it is way, way, way closer than all other stars.

Does the sun have any moons?

Asked by Wiki User

no its doesnt have any moons. because its to hot for it but they consider the planets to be the suns moons

What do stars spend all their time doing?

User Avatar

Asked by Wiki User

Stars spend the majority of their existence undergoing a dynamic process called nuclear fusion, where they convert hydrogen into helium in their cores. This process releases an immense amount of energy, producing light and heat. The balance between gravity pulling inward and the pressure from nuclear fusion pushing outward determines a star's stability.

Throughout their lifecycle, stars evolve based on their mass. Smaller stars, like our Sun, gradually transform into red giants and later shed their outer layers to become white dwarfs. Massive stars undergo more dramatic transformations, culminating in supernova explosions, neutron star formation, or the creation of black holes.

In essence, stars spend their time in a delicate dance between gravitational forces and the intense energy-producing nuclear reactions at their cores, shaping their destinies and contributing to the cosmic processes that govern the dynamics of the universe.

How hot is the sun?

User Avatar

Asked by Lynn Thone Dari Par

The Sun is hot because in its core it is turning Hydrogen into Helium by a process called nuclear fusion. The helium is slightly less heavy then the bits of hydrogen used to make it and this difference in mass is turned into energy (light). This energy keeps the Sun hot and makes it shine.

What is the sun spot cycle?

User Avatar

Asked by Wiki User

This cycle is when the sun heats up the spots on the planets and certin spots get heated on the different planets and the planet has random temperature changes. the sun repedietly goes through this cycle while hiting the same spots on earth as the earth spins around.

What is the sun used for?

User Avatar

Asked by Wiki User

Intrinsically it is not used for anything. However, the radiation from the Sun gives us heat and light. Without it the Easrth would not function and we would not be here.

What type of reaction powers stars?

User Avatar

Asked by Wiki User

It is thermo-nuclear fusion.

That is two atoms of hydrogen aredraw to each other by gravity. They become so close they fuse together and release energy in the process.

This happens billions of times over in a given locality in space, and as such a star forms.

Is the sun a huge fire ball?

User Avatar

Asked by Wiki User

no, a sun is a gas that is full with hydrogen and helium. the hydrogen collide and makes heat. this is called fusion. and the light we see from the sun is the heat and light of the fusion.

Does the Sun move through space?

Asked by Wiki User

I believe it maintains an orbital pattern, though remains in the middle of our system.
