HowDoWhy

I considered answering this in my previous post - How big is the Sun - but found the question so well answered elsewhere that I’ll give it its own post. The short answer is - 1 million. As explained by Ask an Astrophysicist at NASA’s Goddard Space Flight Center - Imagine the Universe, it helps to imagine the Sun as a fishbowl and the Earth as a marble. The diameter of the Sun is 100 times that of the Earth so it would take 100 marbles to stretch from left to right across the inside of solar fishbowl. But you also have to consider front and back; and up and down and everywhere in between. That adds up to a lot of marbles!

Visit GSFC’s Ask an Astrophysicist to read the full answer to - how many times would the Earth fit in the Sun. I think that will wrap up coverage of our amazing little star for now. Please don’t hesitate to ask any questions if I left something out you’re curious about. Check back tomorrow as we’ll begin covering planets!
