Answers
Answer:
The sun is a orange colour type star that's primarily made up of hydrogen and helium. It acts as the main source of energy needed for survival of life on Earth. As we are at a good distance from it we get the correct amount of heat necessary for our survival. IT IS SITUATED IN CENTER OF SOLAR SYSTEM. IT IS VERY HOT . IT IS ONE OF THE MOST IMPORTANT SOURCE OF LIGHT ON EARTH .ITS SURFACE TEMPERATURE IS 5,778 K .ITS SURFACE AREA IS 6.09×10¹²KM²

The sun is one of more than 100 billion stars in the Milky Way.
Explanation:
The sun lies at the heart of the solar system, where it is by far the largest object. It holds 99.8 percent of the solar system's mass and is roughly 109 times the diameter of the Earth — about one million Earths could fit inside the sun.
The visible part of the sun is about 10,000 degrees Fahrenheit (5,500 degrees Celsius), while temperatures in the core reach more than 27 million F (15 million C), driven by nuclear reactions. One would need to explode 100 billion tons of dynamite every second to match the energy produced by the sun, according to NASA.
The sun is one of more than 100 billion stars in the Milky Way. It orbits some 25,000 light-years from the galactic core, completing a revolution once every 250 million years or so. The sun is relatively young, part of a generation of stars known as Population I, which are relatively rich in elements heavier than helium. An older generation of stars is called Population II, and an earlier generation of Population III may have existed, although no members of this generation are known yet.
