37 in the hr diagram 90 percent of all stars are

Around 90 percent of the stars in the Universe are main-sequence stars, including our sun. The main sequence stars typically range from between one-tenth to 200 times the Sun's mass. A star in the main sequence is in a state of hydrostatic equilibrium. called the Hertzsprung-Russell diagram, or H-R diagram.
