¿Por qué se llaman estrellas de neutrones? Es sencillo: están compuestas completamente de neutrones, un elemento básico del átomo. Cuando una estrella masiva agota su combustible, su núcleo central colapsa, convirtiendo cada protón y electrón en un neutrón.

O tamanho de um átomo é extremamente pequeno, com um diâmetro típico de cerca de 0,1 a 0,5 nanômetros . Essa escala é tão pequena que cerca de 50 milhões de átomos de matéria sólida, enfileirados, mediriam apenas 1 centímetro, de acordo com a Britannica. 📏📐 Para colocar em perspectiva: • Um átomo é cerca de 100.000 vezes menor do que um fio de cabelo humano. • O núcleo de um átomo, que contém prótons e nêutrons, é ainda menor. #atomo
