Similarities and differences between Meteoroids, Asteroids, and Comets.
Asteroids and Comets are both classified as near- Earth objects. Asteroids
are made of rock or metal and they are thought to be created in the warmer
inner solar system. Comets are mode of ice, rock, and organic (carbon-
based) compounds, and they are believed to have formed in the cold outer
solar system. Scientists believe that both Asteroids and Comets are ancient
remnants of the earliest years of the formation of our solar system more
than four billion years ago. Meteoroids are smaller rocky bodies that are
results when asteroids collide. Meteoroids are also formed when a comet
passes near the sun and the heat releases dust particles from the comet’s icy
tail. When a meteoroid or asteroid enters the Earth’s atmosphere, it burns,
creating a visible streak of light called a meteor. If the meteor doesn’t turn
into vapor completely and crashes into the earth, it’s called a meteorite.
Meteoroids are similar to asteroids, but they are much smaller. Meteoroids
come from asteroids. Meteoroids, Asteroids and Comets are all rocks from
space that sometimes hit the earth. Meteoroids are made from Asteroids so
they have similar composition as Asteroids. All asteroids travel around the
universe and they form into Meteoroids when Asteroids collide. So these
are some of the Similarities of Meteoroids, Comets, and Asteroids.
