The Sun formed about 4.6 billion years ago in a giant, spinning cloud of gas and dust called the solar nebula. As the nebula collapsed under its own gravity, it spun faster and flattened into a disk.

What was the sun originally made of?
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.
Was the sun a planet?
No, sun is not a planet it is a huge star of hydrogen gas that radiates heat and light . The sun is the closest star to Earth , anchors our solar system .
How long does the sun have left?
Astronomers estimate that the sun has about 7 billion to 8 billion years left before it sputters out and dies. Humanity may be long gone by then, or perhaps we'll have already colonized another planet.
Will the sun burn out?
In about 5.5 billion years the Sun will run out of hydrogen and begin expanding as it burns helium. It will swap from being a yellow giant to a red giant, expanding beyond the orbit of Mars and vaporizing Earth—including the atoms that make-up you.
Is the sun expanding?
It is true that the Sun is very slowly expanding and getting brighter right now. The reason for this is that as it is burning hydrogen to helium in the core the amount of hydrogen there gradually decreases. ... The Sun will then become what is called a Red Giant and its radius will be large enough to envelop the Earth!
Can we survive without sun?
All plants would die and, eventually, all animals that rely on plants for food — including humans — would die, too. While some inventive humans might be able to survive on a Sun-less Earth for several days, months, or even years, life without the Sun would eventually prove to be impossible to maintain on Earth.
How much longer can we live on Earth?
This is expected to occur between 1.5 and 4.5 billion years from now. A high obliquity would probably result in dramatic changes in the climate and may destroy the planet's habitability.
Is there life on the Sun?
The Sun could not harbor life as we know it because of its extreme temperatures and radiation. Yet life on Earth is only possible because of the Sun's light and energy.
What will humans do when the sun dies?
After the Sun exhausts the hydrogen in its core, it will balloon into a red giant, consuming Venus and Mercury. Earth will become a scorched, lifeless rock — stripped of its atmosphere, its oceans boiled off. Astronomers aren't sure exactly how close the Sun's outer atmosphere will come to Earth.
HOW LONG WAS A DAY 4 billion years ago?
4 billion years ago, the moon was a bit closer and Earth's rotation was faster — a day on Earth was just over 18 hours.
What if the sun exploded?
The good news is that if the Sun were to explode – and it will eventually happen – it wouldn't happen overnight. ... During this process, it will lose its outer layers to the cosmos, leading to the creation of other stars and planets in the same way that the violent burst of the Big Bang created Earth.
How many Earths are there?
NASA estimates 1 billion 'Earths' in our galaxy alone. There are a billion Earths in this galaxy, roughly speaking.
Are there planets bigger than the sun?
Explanation: To begin with planets, as that is the easiest question to answer, there are no planets bigger than the Sun or even close to the size of the Sun. At about 13 times the mass of Jupiter a planet becomes what is referred to as a "brown dwarf".
