The amount of metals (metallicity) in the star.
Our sun is a population I star [See related question]
However, age can also be a determining factor as we know the Universe is about 13.75 years old, and our Sun is only 4.6 billion years old, so in those terms it's a youngster.
A person who is involved in the astronomical study of sun is called a Heliologist
nebula
Sunspots and convection cells
All knowledge about the universe from the atom to the cell to the person to the earth to the sun to the farthest reaches of existence.
This is called the Geocentric model, from the latin prefix "Geo-" for earth or ground. This was dropped by the scientific community at the beginning of the renaissance for the Heliocentric model, which states that the sun is the center of the universe. However, even this has been abandoned. The general consensus now is that the universe has no definite center or, if it does, we can never find it due to the dimensional 'curvature' it has.
Aristarchus of Samos thought that the sun was at the center of the universe and some "educated" greek people thought that the earth was the center of the universe but they were dead wrong because modern science now has evidence that the sun is the center of the universe.
The Sun was formed about 4.57 billion years ago whereas the universe is 13.75 ±0.17 billion years old at current best guess. The sun is about one third the age of the universe.
The universe then the sun then the earth:)
The sun was the center of the universe is an example of:
I think it is because there is not enough sun to cover the universe since the sun is smaller than the universe and becasue the sun over powers the world and the chemicals in the air here are different to the ones in the universe which makes the world lighter. I'm not sure how to put it to make you guys understand it so that is the best I could do, Sorry :(
Nicolaus Copernicus found that the sun is in center of the universe
Yes, the sun is considered an average star in the universe.
There is a single sun in our own solar system, but not in the universe. There are trillions upon trillions of suns (or stars) in the universe.
Universe >> Milky Way galaxy >> Solar System > Sun >> Earth
No. The sun exists as inside the universe and was created after the big bang. Nothing (that we know of) existed before the universe.
Earth, Sun, Andromeda galaxy and then the universe. increasing size------------------------->
it was Nicolaus Coppernicus who discoveered that the sun is the rest center of the universe
