Meteors are by definition small. You must be talking about asteroids? Even if that's the case, no asteroid would be big enough to disrupt this planet's (presumably earth sized) orbit that severely. If Ceres, the largest known asteroid (really a dwarf planet - in between an asteroid and a planet) hit Earth, it wouldn't even make any noticeable changes to our orbit. Such an impact would surely wipe out all life on the planet and make it a big molten mess. For comparison, the asteroid that wiped out the dinosaurs is thought to have been 10 km in diameters. Ceres is 975 km in diameter.
Basically, it would never happen.
