Our sun is a yellow dwarf star, a hot sphere of burning gases, 27 million degrees F. at the core. It is composed of 71% hydrogen and 27% helium. It is about 864,000 miles across and about 93 million miles away from us. It takes only about 8 minutes for light from the Sun to reach the Earth.
Just like the planets, the Sun rotates on its axis. It makes one full rotation about once a month.
It is one of billions of other similar stars spread across our Miky Way Galaxy.
The Biblical record states that it was created on the fourth day of creation to light up the day on the Earth.
The gravity of the Sun holds all the objects in our solar system in their places. Its magnetic field and electrically charged gases effect everything around us. Our seasons, weather, and climate depend on its influence.
