Sizing up the Crab

Currently located at a distance of about 6,500 light years (In common English, very very very far away) from Earth, the nebula has a diameter of 11 light years (Still in English, WOW) and is expanding at a rate of about 1,500 kilometers per second. (Imagine YOU expanding that fast!) So the nebula is expanding 285,120,000 miles a day. In a month that would be 59,875,200,000 billion miles. That's 718,502,400,000 billion miles in a year!

Are you still confused? Well It's so big, that it can't even fit into the sun once. Do you know how big the sun is? The Sun's diameter is 1.4 million kilometers. About 1,000,000 Earths could fit into the sun. About 74,815,267 suns can fit into the Crab Nebula.
So about 74,815,267,000,000 Earths could fit into the Crab Nebula.
That's A LOT!

I couldn't find a picture of the Crab Nebula next to the Earth OR the
Sun so here's a cool picture of the Crab alone
