Webkilometers, on this scale of the clay balls, how big would each of the ten ‘planetessimals’ have been that collided to form the final planet? Answer: Suppose the big balls final diameter is 45 = X/20 and so . X = 5300 km. This is a bit larger than the diameter of our moon (3,500 km). Problem 7 WebApr 6, 2024 · This potential supermassive black hole, weighing as much as 20 million Suns, has left behind a never-before-seen 200,000 light-year-long trail of newborn stars. The streamer is twice the diameter of our Milky Way galaxy. It’s likely the result of a rare, bizarre game of galactic billiards among three massive black holes.
