Antares is about 800 times larger than our Sun. The Sun is about 109 times larger than The Earth. So Antares is about 87,200 times larger than The Earth. You could fit about 663,054,848,000,000 (663 trillion) earths into Antares. That number even makes the US National Debt look small (although that's increasing by $2.85Billion/day)! There's always something much bigger than our problems. I'm amazed by our Universe and intrigued by our knowledge of it. #SoBaffled #CarlSagan #ItsLateImTired
