Spiral galaxy larger than the Milky Way, with five supernovae seen since 1909.
You see the Pinwheel Galaxy as it was about 21 million years ago.
| Across | 178,400 light-years |

| Distance from us | about 21 million light-years |
| How big it looks | about 29 arcminutes — the full Moon is about 30 |
We use about 21 million light-years, from the tip of the red-giant branch (Beaton et al. 2019). A newer measurement with the James Webb Space Telescope gives about 22.4 million.
