I noticed this and thought it worthy of inclusion here. It's huge, so they say, and dwarfs even Jupiter, and it's very far out, 15,000 astronomical units. That compares impressively with 40 units, which is how far out Pluto is. Our Earth is about 93 million miles from the Sun, which one astronomical unit is defined as being. This is why astronomy fascinates me--the incredible distances involved.
