What Is an Object in the Sky?

When people think of objects in the sky, they may think of planets, the sun, moon, and constellations. Many other bodies orbit Earth and the sun, however. The sky below Earth’s atmosphere holds many interesting objects as well. We may not need a telescope to see them, but they are no less awe-inspiring. Readers are introduced to the dazzling phenomena of stars, galaxies, lightning, meteoroids, comets, auroras, rainbows, black holes, and even satellites and space junk. Any reader who has ever looked up at the sky in awe and wonder will find much to thrill to in these pages.
