Classification+of+Stars

Stars can be very different from one another in many ways, yet many of those ways are related. For instance, stars can be classified by size. Stars' sizes can differentiate extremely. The main types of stars are Red Dwarf Stars, Yellow Stars, Giant Stars, Super Giant Stars, and Blue Giant Stars.


 * White Dwarf Star - Slowly burning, white, and small. Example = 40 Eridani B


 * Yellow Star - Medium-sized star; lives for about 10 billion years; when it dies, it swells, leaves behind gas, and makes a Planetary Nebula. Example = The Sun[[image:http://www.kidsastronomy.com/images/planetarynebula2.jpg]]


 * Giant Stars - Large stars, burn very brightly, it is a Yellow star when it expands, but before it makes a Planetary Nebula. Example = Alcone[[image:https://encrypted-tbn0.google.com/images?q=tbn:ANd9GcQNH_STJO706u-C0xJjgqY-BDhPAJFztfihzDxPRmf59xzzUCX4]]


 * Super Giant Stars - Giant Stars, but bigger. Example = Betelgeuse[[image:http://t1.gstatic.com/images?q=tbn:ANd9GcQyDUUWc0cpHlQnmBSo9eu09jo3tpVvh8TW1wperpTPQELFcFDU2wtbGcia]]


 * Blue Giant Stars - Very hot, very bright, they die by exploding into a supernova. Example = Rigel[[image:https://encrypted-tbn3.google.com/images?q=tbn:ANd9GcQT5UXeo-sirT-JKEKHfe94IspT96MNIxp05g4aEWuRZIGFy2Qb1g]]


 * Neutron Stars - Star so dense, it is only 20 km across yet has more mass than our star. Example = CP 1919[[image:http://www.jodrellbank.manchester.ac.uk/news/2006/rrats/virtual.jpg width="298" height="300"]]
