O-type main-sequence stars are bigger and hotter than all of spectral main-sequence stars. They have temperature more than 30,000 kelvin, and size above 10 radii of Sun, and mass is above 20 masses of Sun. In milkyway only 20,000 O-type stars exists. Their life time is shorter than any type of stars and they end up in supernovae become neutron star or a black hole. Before going supernovae they become a red giant or more massive O-type stars become Wolf-rayet stars.<br />This video is made with blender eevee rendering engine, <br />Like and Subscribe.<br /><br />Instagram - <a href="http://www.instagram.com/gghirendra" target="_blank" rel="nofollow">http://www.instagram.com/gghirendra</a><br /><br />#Otype #starsizecomparison #blender<br />...<br /><a href="https://www.youtube.com/watch?v=nt4wUd6M_lw" target="_blank" rel="nofollow">https://www.youtube.com/watch?v=nt4wUd6M_lw</a>
