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.
1. The size and mass. Derived from its rate of hydrogen to helium conversion.
2. Color. (white) It's in the main Sequence stage.
3. Distance from other systems. (sun is a 2nd generation star created from remnants of older stars)

the existence of heavy elements in its composition
I believe this was deduced from the age of the oldest known rocks. This, in turn, was obtained from methods that rely on the decay of radioactive isotopes.
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.
Sun is a Star of Fire in the universe.
The universe revolves around the sun
The universe then the sun then the earth:)
Ptolemy put the Earth at the center of his model of the universe , and said that the Sun , the moons , the planets ,the asteroids , comets , and meteors orbit the Earth and the Earth was the center of the universe.
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 :(
Scientific evidence gathered after the telescope was invented.
Nicolaus Copernicus found that the sun is in center of 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
