Cepheus A (also known as Cep A) is a star-forming region located in the constellation of Cepheus. It is one of the nearest sites of massive star formation, situated approximately 2,300 light-years (700 parsecs) from the Solar System. Cepheus A is notable for its dense molecular clouds and ionized gas, where massive protostars are actively accreting material, providing a key laboratory for studying the early stages of stellar evolution in high-mass stars.
