a) A star is a very large ball of bright glowing hot matter in space. Stars are held together by gravity. They give out heat and light because they are very hot. For example, the sun.
b) A comet is an icy, small Solar System body that, when passing close to the Sun, warms and begins to release gases, a process called outgassing. This produces a visible atmosphere or coma, and sometimes also a tail. Example, Halley’s Comet.
c) A meteoroid is a small rocky or metallic body in outer space. Meteoroids are significantly smaller than asteroids, and range in size from small grains to one-meter-wide objects. Example, fragments from an asteroid.
d) A galaxy is a gravitationally bound system of stars, stellar remnants, interstellar gas, dust, and dark matter. Example, the Milky Way Galaxy.
