aren't pulsars and magnetars very small when talking about stars and planets? Google's AI says about 20km in diameter but would need to double check that. On the other hand, IIRC the energy output of a pulsar compared to its physical size is pretty scary. You wouldn't want one in your neighborhood.
- rkagerer 1y agoYes. Here are fact checks for those who don't trust the easy AI answer: https://www.britannica.com/science/pulsar https://www.britannica.com/science/pulsar https://en.m.wikipedia.org/wiki/Magnetar#Description https://en.m.wikipedia.org/wiki/Magnetar#Description They are both forms of neutron stars, which average around 20km but are the densest objects known to man. Fun fact, one sugar cube of their material would weigh about as much as a mountain (https://imagine.gsfc.nasa.gov/science/objects/neutron_stars1.html https://imagine.gsfc.nasa.gov/science/objects/neutron_stars1...).
