The sun is a massive fusion engine, which gives off its heat by radiating it into space. We call the fusion processes stellar nucleosynthesis. The nuclear fusion reactions produce zillions of watts of heat. It's about 383 billion billion megawatts, which is 3.83×1026 W, and it does that every second. That's a lot of energy. Use the link below to read about the sun in the Wikipedia post. And if you're feeling brave, use the other one to the post on the fusion process itself. You'll be measurably smarter if you read all of that article!
What else can I help you with?
Are red stars the oldest stars?
Red stars are not necessarily the oldest stars. Red stars are low-temperature stars that can be both old and young. The age of a star is determined by various factors, including its mass and chemical composition, rather than just its color.
Are stars all the same color?
Stars come in different colors based on their temperature. Hotter stars appear blue or white while cooler stars can appear red or yellow. The color of a star is an indication of its temperature and stage in its life cycle.
What are small red stars called?
Small red stars are called red dwarves. They are the least luminescent and coldest stars.
Are red giant stars the largest?
No, red giant stars are not the largest stars in the universe. There are stars known as supergiant and hypergiant stars that are even larger than red giants. These stars can be hundreds to thousands of times larger than our Sun.
Are red stars bigger than blue stars?
Red stars can be smaller or larger than blue stars as there are two types of red star. Red dwarfs are much smaller than blue stars while red giants are much larger than blue stars.
Is red stars cold?
No. Red stars emit less energy so they are cooler than hotter blue stars.
How do blue stars differ from the red stars?
Blue stars are hot, and red stars are cold. You'd think it would be the other way around, but weirdly enough, it's not.
Are red stars the oldest stars?

What Colour Is A Star That Is Very Cold?
There are no stars that are very cold. Even the "coolest" stars are at thousands of degrees hot; if they weren't capable of supporting nuclear fusion, they would not be stars at all - they would be planets. The "coolest" stars glow a deep red, and are not very bright.
What stars are hot and which are cold?
All stars are hot. Their temperature can be determined by their color. The "coolest" stars are red in color. As temperature increases stars will go through orange, yellow, white, and finally blue for the hottest stars.
Are stars all the same color?
Stars come in different colors based on their temperature. Hotter stars appear blue or white while cooler stars can appear red or yellow. The color of a star is an indication of its temperature and stage in its life cycle.
Which is cooler the blue stars or the red stars?
Red stars are cooler than blue stars
What are examples of red stars?
Betelgeuse and Aldebaran are red stars.
When was When the Stars Were Red created?
When the Stars Were Red was created in 1991.
What are small red stars called?
Small red stars are called red dwarves. They are the least luminescent and coldest stars.
Are red giant stars the largest?
No, red giant stars are not the largest stars in the universe. There are stars known as supergiant and hypergiant stars that are even larger than red giants. These stars can be hundreds to thousands of times larger than our Sun.
