The term "stars" here refers to angels.

Jude 12-13
12 These are spots in your feasts of charity, when they feast with you, feeding themselves without fear: clouds they are without water, carried about of winds; trees whose fruit withereth, without fruit, twice dead, plucked up by the roots;

13 Raging waves of the sea, foaming out their own shame; wandering stars, to whom is reserved the blackness of darkness for ever.
KJV

Revelation 8:10-11
10 And the third angel sounded, and there fell a great star from heaven, burning as it were a lamp, and it fell upon the third part of the rivers, and upon the fountains of waters;

11 And the name of the star is called Wormwood: and the third part of the waters became wormwood; and many men died of the waters, because they were made bitter.
KJV

Revelation 9:1
9 And the fifth angel sounded, and I saw a star fall from heaven unto the earth: and to him was given the key of the bottomless pit.
KJV

If you consider the use of stars in Jude 13, and the star that fell from heaven in Revelation 9:1, it becomes obvious that the great star that fell from heaven is not a meteor but a great "fallen" angel. This would be Satan in his guise of antichrist.

Let's go on here, in Jude 13 there is talk of raging waters. This is clearly explained to us in Revelation 17:15 below.

Revelation 17:15
15 And he saith unto me, The waters which thou sawest, where the whore sitteth, are peoples, and multitudes, and nations, and tongues.
KJV

Consider this, if the great star that falls from heaven is an angel whose name is wormwood which is Greek for bitterness and in Hebrew it is curse as in poisonous.

OT:3939 (Hebrew):
la`anah (lah-an-aw'); from an unused root supposed to mean to curse; wormwood (regarded as poisonous, and therefore accursed):
KJV - hemlock, wormwood.

NT:894 (Greek):
apsinthos (ap'-sin-thos); of uncertain derivation; wormwood (as a type of bitterness, i.e. [figuratively] calamity):
KJV - wormwood.

The definition of wormwood is perfect for the antichrist since he will turn people away from the true Christ and will cause a spiritual death for all that belive that antichrist is the true Christ.

Amos 5:7-9
7 Ye who turn judgment to wormwood, and leave off righteousness in the earth,

8 Seek him that maketh the seven stars and Orion, and turneth the shadow of death into the morning, and maketh the day dark with night: that calleth for the waters of the sea, and poureth them out upon the face of the earth: The Lord is his name:

9 That strengtheneth the spoiled against the strong, so that the spoiled shall come against the fortress.
KJV

When people worship a false god, be it a man made idol or an angel disguised as the true Christ this will bring about wormwood which is bitterness and a spiritual death because all living are in Christ, not some idol.

Deuteronomy 29:17-20
17 And ye have seen their abominations, and their idols, wood and stone, silver and gold, which were among them:)

18 Lest there should be among you man, or woman, or family, or tribe, whose heart turneth away this day from the Lord our God, to go and serve the gods of these nations; lest there should be among you a root that beareth gall and wormwood;

19 And it come to pass, when he heareth the words of this curse, that he bless himself in his heart, saying, I shall have peace, though I walk in the imagination of mine heart, to add drunkenness to thirst:

20 The Lord will not spare him, but then the anger of the Lord and his jealousy shall smoke against that man, and all the curses that are written in this book shall lie upon him, and the Lord shall blot out his name from under heaven.
KJV
