New Defender's Study Bible Notes
6:13 stars of heaven fell. The Greek word for “star” (aster) can mean any object in the heavens, including planets, asteroids and meteorites. Planetary scientists have long been concerned with the possibility that a swarm of asteroids or giant meteorites would collide with the earth in its orbit, and that seems to be what John describes here. Perhaps this also is part of the trigger which unleashes the great earthquake. Isaiah says that when this happens, “the host of heaven shall be dissolved,” and that “the stars of heaven and the constellations thereof shall not give their light” (Isaiah 34:4; 13:10), evidently blotted out by the same volcanic dust cloud that darkens the sun.
