Meteoroids 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 ,{ asteroid, comet, meteor, meteoroid } 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 { asteroid, comet, meteor, meteoroid } , are studied by scientists to gain a better understanding of our solar system.

1. A burning streak of light, called a Meteor.

2.The rocky bodies that survives the fall to the planet’s surface are Meteorites.

Explanation:

Let us see the difference between them.  

Asteroids: They are the remnants of a broken planet orbiting the sun in between Mars and Saturn.  They are small rocky bodies from a tennis ball size to larger ones weighing a few tones. Meteoroids: They are the small rocky objects of pebble size formed due to the collision of asteroids. Meteors: These are pebble size objects that enter Earth's atmosphere and burns off by forming streaks of light. Meteorites: These are rocky objects bigger than meteors than don't burn out completely and fall on the earth's surface. Comets:  These are objects mainly made of dust and ice that orbit the sun in a highly elliptical orbit. This composition makes a long tail when approaching the sun.
