Main Sequence Star Drawing

Main Sequence Star Drawing - 90% of all stars are in the main sequence, from bright, blue stars at the upper left, to dim, red stars at the lower right. Web this reveals some distinctive patterns. One of the fundamental forces in the universe is gravity. About 90 percent of the stars in the universe, including the sun, are main sequence stars. The sun is at this. Given a model that represents a star at one stage of its evolution, we can calculate what it will be like at a slightly later time. Stars spend about 90% of their lives in this stage. By the end of this section, you will be able to: Main sequence stars a normal star forms from a clump of dust and gas in a stellar nursery. It is the force that holds us on earth.
