Meteors have been pretty rare for me, too. I've had about five since they were introduced in the game a couple of years ago, and all in different games. (Three in different Sunset Valley games, one in Twinbrook, and one in Bridgeport.) Two of those times they hit rabbit holes, too, and my sims were at work. The others my sims were just out in the yard. One was using the water slide, one was walking out to the car to go to work, and one was my unicorn just grazing in the backyard. I've never had the telescope trigger a meteor, oddly enough.
The mods are nice, though, if you want to eliminate the chance entirely. At one point I thought that the fireproof homestead reward would (since meteors cause fires) but it turns out that it just lets the meteors fall without causing fires. Your stuff can still get crushed and charred, there is just no fire to put out.
