Proof that Sun is a star deduces from the following scientific experiment
"..
Stars are space objects that produces their own energy through fusion reaction of gasses. They are like round, gas burning, energy producing luminous orbits. The sun is a star because it produces energy by the fusion reaction of Helium turning into Hydrogen. Attachment of the spectroscopes to the telescopes, which gave out the signature spectra of different stars and it is the closest star to the planet earth. The sun is a perfectly ordinary star -- a great, glowing ball of gas. In its core, it fuses hydrogen into helium, as all stars do for the majority of their lives, in order to generate enough pressure to avoid collapsing under its own gravity.
The sun formed up about 4.5 billion years ago, when a cloud of dust and gas called a nebula collapsed under its own gravity. As it did, the cloud spun and flattened into a disk, with our sun forming at its center. The disk's outskirts later grew by accummulation into our solar system, including Earth and the other planets they orbit the space. The Sun, is so hot that the huge amount of hydrogen is undergoing a constant star-wide nuclear reaction; scientists think that the core of the Sun is a 15 million degree Celsius plasma, a soup of electrons and protons that are stripped from hydrogen atoms. There are about 6000 stars that are clearly visible to the naked eye above Earth,
all stars, like our sun, send out a huge amount of electromagnetic radiation, including light. However, that light spreads out with distance, making it so that only a tiny fraction reaches us. In addition, depending on the temperature of the star, the main color of light sent out by the star changes. Cooler stars put out redder light, hotter stars put out blue or white light. Generally, colors like white or blue are stronger colors (shorter wavelength, higher frequency) and can be seen more easily at far distances than reds, oranges or yellows. Also, some stars are simply larger than others and send out more light.
Gravity is a fundamental underlying force in the universe. The amount of gravity that something possesses is proportional to its mass and distance between it and another object. This relationship was first published by Sir Issac Newton. His law of universal gravitation says that the force (F) of gravitational attraction between two objects with Mass1 and Mass2 at distance D is:
F = G(mass1*mass2)/D squared.
(G is the gravitational constant, which has the same value throughout our universe.)
Einstein's theory of relativity adds to this. His theory predicted that objects with great mass deform space around them, causing light to deflect into them. That has been shown to be true. He also predicted that gravity could travel in gravity waves, which we haven't seen yet.."
