Meteors are not going to hit the earth,for the only thing that will hit the earth is the wrath of God upon the heathen,when it is the time for Him to punish the world for their sins and iniquities against Him,although God will cause hailstones the weight of a talent to come upon them.
Rev 6:15 And the kings of the earth, and the great men, and the rich men, and the chief captains, and the mighty men, and every bondman, and every free man, hid themselves in the dens and in the rocks of the mountains;
Rev 6:16 And said to the mountains and rocks, Fall on us, and hide us from the face of him that sitteth on the throne, and from the wrath of the Lamb:
Rev 6:17 For the great day of his wrath is come; and who shall be able to stand?
It is Jesus going against them,and He is not using meteors to go against them,which Jesus will give them plagues,as outlined of the 7 vials,and at the battle of Armageddon the plague what they shall be given is their flesh will melt off their bones,and Jesus will destroy the man of sin with the brightness of His coming.
God is not trying to destroy the earth,but only going against the heathen,and the flesh is weak,so why would He have to use meteors to go against such weak flesh,and it will be God using His own power over the elements to go against them,and at the end of their punishment the brightness of His glory to go against them.
The stars in Revelation 12 are referring to the fallen angels that Lucifer deceived to go along with him in rebellion against God,and then it states that he wanted to devour the child the comes from Israel,the child Christ Jesus,and the stars sure did not fall back then.
