The Year When Stardust Fell by Raymond F. Jones, Science Fiction, Fantasy (Hardcover) (ISBN-13: 9781463897772)

That night the comet was the only thing in the whole sky. All the stars were smothered by the light of its copper-yellow flame, and, although the sun had set two hours ago, the Earth was lit as with the glow of a thunderous dawn.

In Mayfield, Ken Maddox walked slowly along Main Street, avoiding collisions with other people whose eyes were fixed on the object in the sky. Ken had spent scores of hours observing the comet carefully, both by naked eye and with his 12-inch reflecting telescope. Still he could not keep from watching it as he picked his way along the street toward the post office.

The comet had been approaching Earth for months, growing steadily to bigger proportions in the sky, but tonight was a very special night, and Mayfield was watching with increased awe and half-dread -- as were hundreds of thousands of other communities around the world.

Tonight, the Earth entered the comet's tail, and during the coming winter would be swept continuously by its million-mile spread.
