Material strength classification of meteoroids based on KB, kc, and PE empirical parameters.
| KB group | KB value | kc group | kc value | PE group | PE value | Material association |
|---|---|---|---|---|---|---|
| ast | 8 ≤ KB | IV | kc < 82 km | I | −4.6 < PE | Ordinary chondrite-like |
| A | 7.3 ≤ KB < 8 | III | 82 km < kc < 88 km | II | −5.25 < PE ≤ −4.6 | Carbonaceous chondrite-like |
| B | 7.1 ≤ KB < 7.3 | II | 88 km < kc < 97 km | – | – | Dense cometary |
| C | 6.6 ≤ KB < 7.1 | I | 97 km < kc < 103 km | IIIA | −5.7 < PE ≤ −5.25 | Regular cometary |
| D | KB < 6.6 | Ia | 103 km < kc | IIIB | PE ≤ −5.7 | Weak cometary |
Notes. Parameters are defined according to Ceplecha (1988) and Jenniskens (2023). Material associations are taken from Flynn et al. (2018) and Jenniskens (2023).
