Why Will the Sun Keep Shining for Billions of Years?

What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. Why will the Sun keep shining for billions of years?

The Big Idea

The Sun will keep shining for billions of years because it has plenty of fuel left! The Sun is about 4.6 billion years old and has enough hydrogen fuel to shine for roughly 5 billion more years. There is nothing to worry about.

The Sun's Fuel

Step one: the Sun runs on hydrogen. In its core, the Sun squeezes tiny hydrogen atoms together to make helium. This is called fusion, and it releases huge amounts of energy. That energy becomes sunlight.

Slow and Steady

Step two: the Sun uses its fuel slowly. The Sun is enormous, so even though it burns lots of fuel every second, it has so much that it lasts billions of years. It has already shone for about 4.6 billion years.

Middle-Aged

Step three: the Sun is middle-aged. It has enough fuel to keep shining for roughly 5 billion more years. By then, the Sun will change, but that is far, far in the future. Nobody needs to worry.

A Closer Look

Let's take a closer look at a timeline! The Sun was born about 4.6 billion years ago. Today it's right in the middle of its life. It has about 5 billion years of fuel left. That's a lot of sunny days.

Quick Facts

Quick facts! The Sun is about 4.6 billion years old. It has enough fuel for about 5 billion more. The Sun is a middle-aged star. Sunlight takes about eight minutes to reach us.

Think Like a Scientist

Now, think like a scientist! Draw a timeline of the Sun's life. Mark its birth, today, and about five billion years from now. Add a smiley face for today. Show a grown-up your timeline.
