The Sun is a Star
Have you ever gone stargazing at night? Think about how many stars you will see on an average night. Based on that estimate, how many stars do you think are in our solar system? There is just one, and it is the Sun. All of those stars that you see at night are not in our solar system. Not only is the Sun the only star, but it also takes up more than 99% of the total mass in the solar system. In fact, the Sun is so big that more than one million planet Earth's could fit inside of it!
While the Sun is much bigger than the other planets, it actually isn't that big when compared to other stars in the universe. It's actually a yellow dwarf star, a relatively small type of star. You may be thinking, well then, why does the Sun look so much bigger to me than the stars that I see in the sky? The Sun looks bigger because we're closer to it. Just like other stars, the Sun will eventually collapse and die. In fact, the Sun will end up the same size as our little planet Earth.

Other Sun Facts
Not only is the Sun much bigger than Earth, but it's also much hotter. The inside of the Sun can get up to more than 27 million degrees! To put this in perspective for you, the hottest day ever recorded on Earth was 134 degrees.
Do you know what the Sun is made of? The Sun is a ball of gas, mostly hydrogen and helium. On the surface of the sun, there are dark, cooler spots known as sunspots. These are caused by changes in the magnetic field that is inside of the Sun.
Positive Effects of the Sun
The Sun does a lot of great things for us. For one thing, it's a source of solar energy, which is light and heat. In order to help the environment, scientists have figured out ways for the Sun's solar energy to power things like cars and household items. This energy is renewable, which means it can be recycled.
The Sun also helps us stay healthy. When you're exposed to the Sun, it increases your ability to produce Vitamin D. This strengthens your bones, helps you sleep well and helps you fight diseases. There have also been studies that have shown that the Sun can actually help your mood and keep you happy!
Who doesn't love to watch a beautiful sunrise or sunset? As the Earth rotates, the Sun rises and falls to cause day or night.
Negative Effects of the Sun
Have you ever heard the phrase, 'too much of a good thing'? This means that some things are best enjoyed in moderation. Spending too much time in the Sun can be very damaging to your skin. Not only can it make your skin look older than it is and cause sunburn, it can also lead to skin cancer, which is the most common form of cancer in the world. In fact, there are more than five million cases of skin cancer diagnosed per year.
While the Sun looks big in the sky, it's actually a dwarf star, a relatively small type of star. There are sunspots caused by changes in the magnetic field that is inside of the Sun on its surface that are darker and cooler. The Sun is a great source of solar energy, which provides heat and light that we can use here on Earth.
