Celestial BodyDefinition
  1. rotation neutron star which generates regular bursts of radiation
  2. two stars that orbit around a common center of mass
  3. the imploded core of a massive star produced by a supernova explosion
  4. a component of the Universe made up of gas and a large number of stars held together by gravity
  5. an object whose gravity is so strong that even light can't escape
  6. a large ball of gas that creates and emits its own radiation

Group Two
SatelliteDefinition
