The size of the Sun is...well...

Think the Sun is big? Some stars make it look tiny — one could even swallow our whole solar system!

Our Sun might feel massive — after all, it can fit 1.3 million Earths inside — but in the vast arena of the cosmos, it's actually on the small side.

When compared to some of the largest and brightest stars in our galaxy, the Sun is more like a cozy campfire than a blazing inferno.

Betelgeuse alone is about 700 times the size of the Sun—and Antares is even larger, measuring around 883 times our star’s diameter.

To put that into jaw-dropping perspective: if Betelgeuse or Antares took the Sun’s place, they would engulf the orbits of planets all the way out to Jupiter. And the true titans of the universe go even beyond that.

Stars like Stephenson 2-18 are estimated to be over 2,150 times the size of the Sun, meaning it would swallow basically everything in our corner of the universe....and is also way too big to fit in this image.

"Dr. J." will operate on the basketball court for you

Once upon a time (when I was a little boy), doctors would come to your house to visit you if you were ill.

He was 6'7" and had hands the size of a pizza (yes, he did). And he could jump too. He was Julius Irving, also known as "Dr. J."
