Size an mass o very lairge starns: Maist massive example, the blue Pistol Star (150 M_☉). Ithers are Rho Cassiopeiae (40 M_☉), Betelgeuse (20 M_☉), an VY Canis Majoris (17 M_☉). The Sun (1 M_☉) which is nae veesible in this thumbnail is included tae illustrate the scale o example starns. Yird's orbit (grey), Jupiter's orbit (reid), an Neptune's orbit (blue) are an aa gien.
