I know that VY Canis Majoris is the largest star known, but are there any estimates as to how big the biggest of them all may be? What limits a star to this maximum size?|||It is probable that 180 solar masses was near the cutoff point for massive stars born in the early universe.
The Peony Nebula Star is about 175 solar masses, but it is difficult to measure the stars鈥?temperatures and absolute brightnesses and the masses are derived from stellar models. The conservative view is that 120 solar masses is the cut-off limit for today's massive newly born stars.|||no one knows, but there is a point where if anything gets too massive it will collapse into a black hole.|||the size of 1,000 opossums.|||the Universe is a big place, and there's no way we can possibly know what the biggest star is.|||The theoretical limit for main sequence stars is 150 solar masses.
