How about size. I think we first need to get a sense of size so we can really understand how big this star is. Our Sun is 870,000 miles across (or 1.4 million km). We could probaly fit the Earth inside the Sun 1 million times. The biggest star VY Canis Majoris is so big the Sun would fit inside this about 2100 times. Traveling. If you where to fly a plane around the world it would take about 40-50 hours (depending on fuel stops etc). Now, if you where to fly around the biggest star itâs believed it could take 1100 years!!
She noted that the largest stars are the coolest. So even though Eta Carinae is the most luminous star we know of, itâs extremely hot â 25,000 Kelvin â and so only a mere 250 solar radii. The largest stars will be the cool supergiants.For example, VY Canis Majoris is only 3,500 Kelvin.he largest known star is VY Canis Majoris; a red hypergiant star in the Canis Major constellation, located about 5,000 light-years from Earth. University of Minnesota professor Roberta Humphreys recently calculated its upper size at more than 1,540 times the size of the Sun.
