Question

An object more massive than the Sun, but roughly the size of a city is a neutron star. Neutron stars are incredibly dense and have a very small radius, resulting in a very high mass-to-volume ratio. They are formed when a massive star undergoes a supernova explosion and its core collapses under gravity. An object more massive than the Sun, but roughly the size of a city, is most likely a neutron star. Neutron stars are incredibly dense and compact, with a mass greater than the Sun but a radius only a few kilometers. This makes them roughly the size of a city while being incredibly massive. Supernova remnants are the leftover debris from a supernova explosion and are not necessarily massive objects themselves. White dwarfs and red dwarfs are both smaller and less massive than the Sun, while brown dwarfs are more massive but much larger than the size of a city.
