If galactic location details weren't provided, I would have jokingly concluded that we finally spotted the nuclear manhole cover :) https://www.jpl.nasa.gov/in

- JumpCrisscross 2y ago> the nuclear manhole cover Manholes can weigh over 250 lbs (113 kg) [1]. Accelerating that mass to 25k mph takes about 7 GJ. Brown dwarfs are around 10 ^ 27 kg. That takes sabout 10 ^ 11 GJ to get to 1mm mph. To put that into perspective, the scale of the energy difference between these phenomena is so vast that were each GJ a second the interval it would define would span 32bn years, or roughly twice the age of the universe.
