> But GCIRS 13E appears to be 26,000 light-years away. Hint: 3.16 light-years x 20 is not even close to 26,000 light-years. The article isn't describing how far away from Earth IRS 13 is. It's describing how far from the galactic center it is (0.1 light-year, not 26,000 light-years). To help narrow down what the author is referring to by "one end of our solar system to the other", one can divide 0.1 light-year by 20 to get 0.005 light-year, which is about 316 AU. I'm going to assume th⁹at the reference is to the heliosphere, then, since it's apparently about 300 AU across: "The Sun's stellar-wind bubble, the heliosphere, a region of space dominated by the Sun, has its boundary at the termination shock. Based on the Sun's peculiar motion relative to the local standard of rest, this boundary is roughly 80–100 AU from the Sun upwind of the interstellar medium and roughly 200 AU from the Sun downwind."[1] [1] https://en.wikipedia.org/wiki/Solar_System https://en.wikipedia.org/wiki/Solar_System
