  3. PHYSICAL CHARACTERISTIC • Nucleus is thecore of a comet . • Cometarynuclei are composed of an amalgamation of rock, dust, water ice, and frozen gases • Coma is produced from the steams of dust and gas forming a thin atmosphere around the comet.

  4. What are asteroids? • Small rocky, metallic or both, that orbit the sun. • circle our central star known as asteroid belt. • Minor planets • Larger ones are called planetoids

  5. CLASSIFICATION ORBITAL MECHANICS COMPOSITION However, it is more common to refer asteroids by their orbital characteristics

  6. Asteroid Belt the asteroid belt contains millions individual objects. Solar System located roughly between the orbits of the planets Mars and Jupiter asteroid or minor planets.

  7. Trojan Asteroids the sun along the same path as one of the planets the sun on a similar orbital path as that of Earth in the vicinity. Earth trojansless energetically costly to reach than the Moon have a hundreds of times more distant.
