The angular resolution of the Hubble and James Webb telescopes are about the same - both are around $0.05$ to $0.1$ arc seconds or about $4 \times 10^{-7}$ radians. If we express the angle $\theta$ in radians then the distance subtended by that angle at a distance $r$ is just $r\theta$. Starman is about fifty million kilometres away, and at that range \$4 \...
