I appreciate these astro threads this time of the year since the stars are gone and won’t be back until the first of August...

There's plenty of stars up in the summer sky. They don't go on vacation. Also in the summertime, we have constellations like Sagitarious. In the direction of Sagitarious is where the center of our Milky Way galaxy lies. Astronomers estimated a black hole about 3 million times as massive as our Sun resides there (rent free). The BH's distance from us is approximately 30,000 light years, one light year being the distance light travels in a year at its steady speed of 186,000 miles per second. And one LY works out to be about 6 trillion miles (6,000 billion miles). To get the actual distance to the center of the galaxy and the supermassive black hole there, multiply THAT number by 30,000.

Actually we can’t see Sagittarius from here. Ditto the ISS and the Space Shuttle. It’s all rumor.
