These will eventually become red supergiants over time. They become blue supers through radiation pressure, convection and the large burning of hydrogen. Red giants are in a late phase of the star cycle and have burned most on the hydrogen at the core.īlue supergiant stars are in between the size of red giants and blue hypergiants. Red giants are larger luminous stars that have low mass. The star called Pollux is an orange giant, with the orange colour indicating that the surface temperature of the star is lower than that of a main-sequence star. Orange giants are stars that are sized between blue and red giants. Blue giants are also very hot, and are quite rare compared to other starts. Yellow dwarfs are a size between red dwarfs and blue giants.īlue giants are the smallest of the 7 larger type stars, and larger than yellow dwarfs. Our sun is a yellow dwarf, so yellow dwarfs are similar in size to our sun. Yellow dwarfs are main sequence stars which means that they are in the stable range of their life cycle. The closest star to earth, called Proxima Centauri is a red dwarf. Larger than white and brown dwarfs but smaller than yellow dwarfs, like our sun. Red dwarfs are one of the most common stars in the Milky Way galaxy. Brown dwarfs are around the same size of a large planet in the solar system. Not officially a star and not officially a planet, but somewhere in between based the sizes of the stars. The mass of these stars can be equal to that of the sun.īrown dwarfs are strange altogether. White dwarfs are the smallest type stars, with a similar size to earth, and with extreme mass. The last 7 star sizes are the larger type stars. ![]() The first 4 star sizes are the smaller type stars. ![]() The star sizes starting by the smallest by type are: Starting below from the smallest to the largest that we know of right now and in the years to come, we will discover many more sizes, from very small to very large, and everything in between. Here we will learn about the different sizes of stars that are grouped together in categories. And through continuous study, we have found many different types of stars with many different star sizes. ![]() With an infinite amount of stars in the universe, and the billions in our own galaxy, as we search through the stars that we can see with current technology, we have come across many weird and wonderful stars.
