Why do we see stars in the sky?
In the sky, you can see the sun, stars, and the moon. The sun is up during the day. It is very hot. The sun gives us light and heat. Plants need the sun to grow. We can see the stars at night.

Is the Sun a normal star?
It is often said that the Sun is an "ordinary" star. That's true in the sense that there are many others similar to it. But there are many more smaller stars than larger ones; the Sun is in the top 10% by mass. The median size of stars in our galaxy is probably less than half the mass of the Sun.

The different layers of the Sun The Sun, like other stars, is a huge spherical object made of hydrogen and helium. Its diameter reaches 1.400.000 km, or 109 times the Earth’s diameter; but is 4 times less dense than the Earth due to its composition. The Sun is not only made of the glowing gas that we see with a telescope.

and just twinkles in the night sky like the other stars. Because the Sun is by far our closest star, we can learn a great deal about all stars by studying it. Sunspots Sunspots are dark splotches on the Sun caused by the appearance of cooler (4000 degrees Celsius) areas amidst the roiling gases on the surface (6000 degrees C).
