There are approximately 200-400 billion stars in our Milky Way Galaxy alone.

Did you know? 

Each galaxy contains hundreds of billions of stars and there is estimated to be over 100 billion galaxies in the universe. So the total number of stars in the universe is mind boggling, estimated to be at least 70 sextillion and possibly as high as 300 sextillion, that's 300,000,000,000,000,000,000,000!!!!!

Stars are usually between 1 and 10 billion years old. Some stars may even be close to the age of the observed Universe at nearly 13.8 billion years old.

Did you know? 

Binary stars and multi-star systems are two or more stars that are gravitationally linked, they orbit around each other.

Did you know? 

Stars form in nebulas, which are large gases areas. As gravity attracts more and more gas, young stars (called protostars) start to form in thick molecular gases cloud areas of the nebula.

Once nuclear fusion has began in the core, a star is sufficiently fuelled to spend the majority of its life as a main sequence star in its most stable form.

Did you know? 

The most common star, are red dwarfs. They are less than half the size and mass of our Sun, and burn their fuel very slowly so live longer than any other type of star, over 100 billion years. Red dwarfs are cooler than most stars and so shine less, eventually getting dimmer they do not explode.

Did you know? 

A brown dwarf forms if a star cannot get hot enough to reach nuclear fusion. Its failed to become a proper star but is still not a planet because it does glow dimly.

Did you know? 

As yellow dwarf stars like our Sun start to run out of hydrogen fuel, the core shrinks, heats and pushes out the rest of the star turning it into a red giant.

Did you know? 

Red supergiants, such as Betelgeuse in the constellation Orion make our Sun look small, 20x its mass, and 1,000x larger. Red hypergiants such as the largest known star VY Canis Majoris are even bigger, over 1,800x the size of the Sun.
