Physical properties and orbital and trajectory parameters of a group of large Type I meteoroids originating in the Oort cloud found in the literature.

Meteor name a, [au] e i, [ °] Q, [au] End height, [km] Beginning velocity, [km/s] Photometric mass, [g] PE TJ
MORP #441 [1] 24.7 0.969 159.7 48.7 61 70.3 13; 20 [4] −4.04 −0.78

Karlštejn fireball [2,3] 3.5 0.71 137.9 5.985 65.79 64.81 200; 33 [4] −4.53 0.64

Alberta fireball [4] 104 0.994 121.4 207 46.5 62.1 1800 −4.49 −0.46

FH1 [5] 1.07 177.18 112.6 73.7 187 −4.173

Notes. More recent mass estimates result from using modern luminous efficiency of Borovička et al. (2020). For the hyperbolic meteor FH1, some orbital elements are not defined. [1] Halliday et al. (1996); [2] Spurný & Borovička (1999a); [3] Spurný & Borovička (1999b); [4] Vida et al. (2023); [5] Peña-Asensio et al. (2024).
