Eteoroids are small objects in space, usually made of rock or metal. These bodies often get close to a planet and fall through its atmosphere. A burning streak of light, called a "Blank" , is visible as it falls through the sky. Sometimes the object does not burn up completely and a part of it survives the fall to the planet’s surface. These rocky bodies, called
"Blank", are studied by scientists to gain a better understanding of our solar system.

The first blank is: Astroid, Meteor, Comet, or Meteoroid.

The second Blank is: Asteroids, Comets, Meteoroids, or Meteors.
