how was the sun made?

Question

how was the sun made i really need to know

Answer 1

only God noz!

Answer 2

The Sun and planets in our solar system formed when a rotating cloud of dust and gas in space collapsed, or condensed, due to the gravitational attraction between the particles in the cloud. A nearby supernova explosion may have triggered the collapse, or a random fluctuation in the density of the cloud may have started the process. The Sun formed at the center of the spinning cloud, while the debris that condensed into planets formed a flattened disk revolving around the Sun. When the Sun reached its present size about 4.6 billion years ago, it was hot enough inside to ignite the nuclear reactions that make it glow.

The Sun cannot shine forever, because it will eventually use up its present fuel. The nuclear fusion reactions that make the Sun glow depend on the element hydrogen, but the hydrogen in the Sun's core will eventually run out. Nuclear reactions have converted about 37 percent of the hydrogen originally in the Sun's core into helium. Astronomers estimate that the Sun¹s core will run out of hydrogen in about 7 billion years.

The Sun will grow steadily brighter as time goes on and more helium accumulates in its core. Even as the supply of hydrogen dwindles, the Sun's core must keep producing enough pressure to keep the Sun from collapsing in on itself. The only way it can do this is to increase its temperature.

The increase in temperature raises the rate at which nuclear reactions occur and makes the Sun brighter. In 3 billion years, the Sun will be hot enough to boil Earth¹s oceans away. Four billion years thereafter, the Sun will have used up all its hydrogen and will balloon into a giant star that engulfs the planet Mercury. At this point in its life, the Sun will be a red giant star. The Sun will then be 2,000 times brighter than it is now, and hot enough to melt Earth¹s rocks. At this time the outer solar system will get warmer and more habitable. The icy moons of the giant planets may warm enough to be covered by water instead of ice.

When the giant Sun uses up its fuel, it will no longer be able to support the weight of its inner layers, and they will begin to collapse toward the core, eventually producing a small, dense, cool star called a white dwarf. The Sun will then have about the same radius as Earth has, but it will be much denser and more massive than Earth. The Sun will become a white dwarf star about 8 billion years from now. After it becomes a white dwarf, it will cool slowly for billions of years, eventually becoming so cool that it will no longer emit light.

Answer 3

The Sun is a near-perfect sphere, with an oblateness estimated at about 9 millionths,[4] which means that its polar diameter differs from its equatorial diameter by only 10 km. While the Sun does not rotate as a solid body (the rotational period is 25 days at the equator and about 35 days at the poles), it takes approximately 28 days to complete one full rotation; the centrifugal effect of this slow rotation is 18 million times weaker than the surface gravity at the Sun's equator. Tidal effects from the planets do not significantly affect the shape of the Sun, although the Sun itself orbits the center of mass of the solar system, which is located nearly a solar radius away from the center of the Sun mostly because of the large mass of Jupiter.

The Sun does not have a definite boundary as rocky planets do; the density of its gases drops approximately exponentially with increasing distance from the center of the Sun. Nevertheless, the Sun has a well-defined interior structure, described below. The Sun's radius is measured from its center to the edge of the photosphere. This is simply the layer below which the gases are thick enough to be opaque but above which they are transparent; the photosphere is the surface most readily visible to the naked eye. Most of the Sun's mass lies within about 0.7 radii of the center.

The solar interior is not directly observable, and the Sun itself is opaque to electromagnetic radiation. However, just as seismology uses waves generated by earthquakes to reveal the interior structure of the Earth, the discipline of helioseismology makes use of pressure waves traversing the Sun's interior to measure and visualize the Sun's inner structure. Computer modeling of the Sun is also used as a theoretical tool to investigate its deeper layers.

Answer 4

TIME: c. 6 e+9 BC

A star explodes in a supernova where the Sun is to be.

TIME: c. 5 e+9 BC

'Twas a dark and stormy night. Suddenly some gas and dust started swirling around, forming a clump.

TIME: c. 4.968e+9 BC

The clump gets smaller and smaller...

TIME: c. 4.925e+9 BC

The clump now is starting to brighten up. It's starting to become the Sun, and smaller clumps also start to swirl to become planets.

TIME: c. 4.875e+9 BC

The Sun is now fully formed, and will continue to burn for about 9 billion years.

TIME: c. 4.650e+9 BC

The planets are now all formed, including big, hot Earth.

TIME: c. 4 e+9 BC

A planet collides into the Earth, forming the moon.

TIME: c. 6.5e+7 BC

An asteroid collides into the Earth, near present-day Gulf of Mexico, bringing the dinosaurs' extinction.

...

You know the rest.

Answer 5

Life for our sun/star began it's life as a cloud of gaseous particles.
In a stellar nursery where gasses attract each other and form the chain reaction gravity attracts the debris and gasses.
This eventually forms into the sun we see today, a star which also has a shelf life our sun, it is estimated to have a remaining life of 4 to 5 Billion years, so we need not be concerned.

Answer 6

The Sun formed by condensation under gravity of cosmic dust and interstellar hydrogen over millions of years.

The gravitational collapse of the Sun caused it to heat as the gravitational potential energy of the particles became the kinetic energy of heat.

The collapse continued until the Sun was hot enough to sustain nuclear fusion reaction in its core. These make the core very hot, and radiation pressure then keeps the Sun from collapsing any further.

It is probably about half way through its life.

Answer 7

Gravity. Every bit of matter in the universe has a gravitational field which attracts it to every other bit of matter. The gravitation field of a single atom is pathetically weak, but on a larger like scale - say that of a planet like Earth or a star like the Sun - it can be overwhelming.

Interstellar atoms, mostly hydrogen gas, drifting through space are eventually drawn together by the mutual gravitation attraction of each atom. As more matter clumps together in one spot, the gravitational field strength increases causing it to draw in even more matter.

While the force of gravity pulls the atoms together, the electrostatic force of each atom - caused by the atom's electrons - keeps them separate. Normally electrostatic force is many times stronger than gravity, but eventually the immense weight of all that matter piled on top of itself is too much. Gravity overcomes the electrostatic force and the atoms are smashed together, resulting in a fusion reaction deep in the core. Thus, a star is born.

Four hydrogen atoms combine to make one heavier Helium atom, plus a free neutron and a gamma ray. This is the basic fusion reaction occurring in the hearth of our Sun. The gamma ray will eventually escape in the form of visible, UV and infrared light. This is what reaches us here on the Earth. The free neutrons bounce into other atoms causing heat. The heat causes the Sun to swell up, partly overcoming the attraction of gravity.

Most estimates say that our Sun is about 4 billion years old and is about half-way through it's lifecycle; it should last another 4 billion years before its hydrogen runs out and the fusion reactions cease.

Answer 8

The sun is a star that is actually in the final stages of existence

It was made by God, some would say. Others dont know

Answer 9

If u want the answer scientificaly:
the sun was made by hydrogen gas clustered togther and after a lot stages the sun was formed.

In religious way :
Then it was created by God at 3rd day of creation

Answer 10

I know it's a burning star and
at some point it blew up and began to burn. Which in turn lit up our planet. We will not see it but it will burn out one day.

However I do sometimes like to think stars are door ways into other universes and one day man might just find a way of opening the door. Just like the dog star scenario. the pyramids on a said day aligned with the dog star and an astral path way opened up.

Answer 11

the same way ...by which a star is made .......as the sun IS a star
------------------------------------------------------------------------------------
Stars are born in dense regions inside giant molecular clouds (GMCs), which are clouds of hydrogen gas and dust between stars. The internal pressure of the clouds prevents them from collapsing in on themselves due to their own gravity, therefore some external cause is needed to induce a section of the GMC to collapse and form stars. A compression wave, or shock, can produce localized regions of high density which may then collapse under their own gravity. A flattened spinning disk of gas and dust is formed, with the material gradually moving to the centre of the disk to form a spherical core, called a protostar. As the core contracts it heats up. A new star is born if enough material accumulates in the core to turn on nuclear fusion, the process which provides the star's energy.
