When was sun made

How did the Sun form?

The sun was born about 4.6 billion years ago. Many scientists think the sun and the rest of the solar system formed from a giant, rotating cloud of gas and dust known as the solar nebula. As the nebula collapsed because of its gravity, it spun faster and flattened into a disk. Most of the material was pulled toward the center to form the sun.

How old is the Sun?

Gazing up at the clear blue sky, our eyes are often drawn to the Sun, that magnificent burning orb that illuminates our days, warms our planet, and supports the growth of our food.

What is the Sun made of?

Here’s how it works. The sun is a big ball of gas and plasma, but what is the sun made of exactly? Most of the gas — around 92% — is hydrogen, according to NASA. It is converted into energy in the sun's core. The energy moves outward through the interior layers, into the sun's atmosphere, and is released into the solar system as heat and light.

What was the original chemical composition of the Sun?

The Sun's original chemical composition was inherited from the interstellar medium out of which it formed. Originally it would have been about 71.1% hydrogen, 27.4% helium, and 1.5% heavier elements. [ 53 ]

How did the Sun become a planet?

The spin caused the cloud to flatten into a disk like a pancake. In the center, the material clumped together to form a protostar that would eventually become the sun. "There is a rotationally supported disk around this protostar," astronomer John Tobin told Space.com about a similar early sun, adding it's a "key element" in building planets.

What type of star is the Sun?

The Sun is a G-type main-sequence star (G2V), informally called a yellow dwarf, though its light is actually white. It formed approximately 4.6 billion [ a ] years ago from the gravitational collapse of matter within a region of a large molecular cloud.
