Difference between Comets, Asteroids, Meteors, and Meteoroids and Meteorites - in 4 minutes

Comets: -

Comets are basically a ball of dust, rock and metal, surrounded by thick icy shell. They always revolve around the sun and when they came very close to sun, their ice sublimate(to pass directly from the solid state to gaseous state and skipping the liquid state). This effect creates halo like appearance around the comets which is called coma and our sun blows away these comas, which gives comets' appearance look like a trails.  Eg: - Hailey's comets and Neowise Comet.

Asteroids: -

Asteroids are basically comets just without the layer of ice. Majority of their kind exists in Asteroid belt (lies between Mars and Jupiter) and Kuiper belt (lies after Pluto). They are rarely directed to Earth but they pose a great threat to life. Though Jupiter, Mars always influence asteroids trajectories. Thank You Jupiter and Mars.

Meteoroids: -

They are just pieces of rocky space debris which are like your younger brother who doesn't care about anything. Technically, meteoroids are larger than dust grain but smaller than asteroids. However, most meteoroids are of the size of pebbles.

Meteor: -

Meteors are just meteoroids but they hit the Earth's atmosphere. They are often referred as shooting star. When they enter the Earth's atmosphere, friction burns them up and gives a flashy appearance in the night sky. They might look big in night sky but their size is just about the size of a pebble.

Meteorites: -

Meteorites are the meteoroids with a better fortunes. They are basically meteors who pass through Earth's atmosphere and strike the surface of the earth. Even though they are of the size of a pebble, they can travel at very high velocity (around 72,000 Km/hr or 20 Km/s). Also, due to their small size, they are just impossible to detect. But, meteorites are rare because hardly any meteor is able to pass through thick Earth's atmosphere.
