Oh, right I should’ve maybe posted this info, but you can mod them to be bigger 
Go to your boundless install folder and assets/archetypes, on my pc the path is
C:\Program Files (x86)\Steam\steamapps\common\Boundless\assets\archetypes
Edit
clientnpceventsettings.json
Modify the values there, notably
meteorBallSkyEffectSize
meteorTrailSmokeEffectSize
meteorTrailHighEffectSize
2.0 makes pretty big meteors, 4.0 makes huge meteors
Boundless has to be restarted for these values to take effect, and they sometimes reset when patches hit.
