Largest known star

Largest known star

I’ve decided no one really reads this, so I am gonna start treating this as a journal of pertinent and/or shit I find cool.

Reading up on stars near the end of their lives in hopes of seeing a supernova close enough to view with the naked eye (during my life) has led me to R136a1.. the largest star known to, well, us.

It is HUGE. I can’t even think of a good way to scale it. Whereas Betelguese and Antares are large enough to almost touch Jupiter, this star would engulf Saturn. The 4 rocky planets are relatively close to the Sun and one another. Then you have the asteroid belt beyond Mars and a very large gap. Then their lies Jupiter.. then another VERY large gap, then Saturn. More than enough room for the 4 orbits of the terrestrial planets (Mercury, Venus, Earth & Mars). Larger stars are relatively cool compared to other ones. This one is within a sattelite galaxy of the Milky Way – the LMC (Large Magellanic Cloud). So it’s brightness from Earth is well beyond what the naked eye can see with a magnitude of about 12. A lot of the brightest stars are between 0 and 1 (the lower the brighter) and the naked eye can see up to around 5, on a nice clear, dark night.
