Question: who made the solar system model of an atom
Answer: In atomic physics , the Rutherford -- Bohr model or Bohr model or Bohr diagram , introduced by Niels Bohr and Ernest Rutherford in 1913 , depicts the atom as a small , positively charged nucleus surrounded by electrons that travel in circular orbits around the nucleus -- similar to the structure of the Solar System , but with attraction provided by electrostatic forces rather than gravity .
