Currently, we can witness comet NEOWISE appear above rthwestern horizon in night sky and people can see it with ir naked eyes. comet is special because it will t return to Earth's skies for about 6,800 years.

Difference between comet, asteroid, meteoroid, and meteors

Comet: Comets are often kwn as swballs of as y are primarily me of ice and dust. Comets revolve around sun like planets in orbit. comet release gasses when it revolves closer to sun, which is also kwn as comet's tail and is visible to us from Earth at night sky. However, t all comet release those gasses because y go extinct over a period of time and those resembles asteroids. 

Asteroid: Asteroids are objects me out of rocks and metals and y too revolve around sun as comets do. An asteroid is larger than meteoroid in size.

Meteoroid: Meteoroids are smaller grains that are expelled from comets or asteroids. Meteoroids like its parents also orbit sun and when reaches atmosphere it vaporizes and becomes meteors, also kwn as 'shooting stars'.
