#15: Asteroid, Meteoroid, Meteor, Meteorite, Comets

A quick revision of the space bodies

NASA has successfully ran a 'kick' test contracting orbit of Asteroid Dimorphos.
In this post, you'll revise the difference between Asteroid, Meteoroid, Meteor, Comet, Meteorites.

Asteroids

- formed from debris of solar system
- MOST found in asteroid belt (not restricted to)
- Either revolve around sun or another celestial body
- smaller than planet, larger than meteoroids

Meteoroids

- Small broken pieces of asteroids or comets
- break away because of collision or action of other forces

Meteors

- A meteoroid enters earth to vaporize and form a streak of light in sky aka meteor
- aka shooting stars
- Made of rocks

Comets

- Made of ice & dust NOT rocks
- Near the sun, the ice & dust vaporize giving it a tail (like meteor)
- It can be seen even in far off space (unlike meteor which is in Earth's atmosphere when seen)

Meteorites

- The meteors that don't burn completely land on earth
- When on earth, they are called meteorites

Summarizing:

- Asteroid -> Meteoroid -> Meteor -> Meteorite
- Comets are far space objects revolving around Sun
