  Small Solar System body (SSSB) - It is an object in the Solar System that is neither a planet,
   nor a dwarf planet, nor a satellite.
Dwarf planet
  It is a planetary-mass object that is neither a planet nor a satellite.
  Dwarf planets orbit our sun, a star.
  Most are located in the Kuiper Belt, a region of icy objects beyond the orbit of Neptune.
  Pluto, one of the largest and most famous dwarf planets, is about 5.9 billion km or 39.48 AU
   away from the sun.
  Dwarf planet Ceres is in the main asteroid belt between Mars and Jupiter.
  Major dwarf planets are Ceres, Pluto, Haumea, Makemake & Eris.
  A satellite is a celestial body that orbits another body.
  There are two types of satellites. These are Natural satellites and Artificial satellites.
  Natural satellites are objects which are formed by nature such as the moon. There are 173
   known natural satellites orbiting planets in the Solar System.
  Artificial satellites are manufactured objects that continuously go round the Earth or some
   other body in space.
  The first artificial satellite was Sputnik I.
Asteroids and Planetoids
  Asteroids are also known as minor planets.
  They are made up of much of the same stuff as planets, but they are much smaller.
  The largest asteroids are called planetoids.
  Asteroids become darker and redder with age due to space weathering.
  Examples of some asteroids are Apophis, Ceres, Pallas, Vesta, Ida, Eros, Gaspra, etc.
99942 Apophis
  It is a near-Earth asteroid.
  The diameter of Apophis is approximately 325 meters.
  The probability of an impact of Apophis on earth on April 13, 2036 has been eliminated.
  It is a small rocky or metallic body travelling through space.
  They are significantly smaller than asteroids, and range in size from small grains to 1 meter-
   wide objects.
  The visible streak of light from space debris is the result of heat as it enters a planet"s
   atmosphere, and the trail of glowing particles that it sheds in its wake is called a meteor, or
   colloquially a shooting star or falling star.
