Maybe missplaced star/Diametor wrong
RX J0822−4300 (alt name: Cosmic Cannonball)
Which is a neutron star is way too far away from the Puppis A suppernova, compared to what wikipedia says. and the supernova itself is way too small compared to what wikipedia says? not sure if this is a mixup in wikipedia or an actual error of some sort
