Dogs cry when they see me. You sleep as i walk by. I am known to drive you mad. What am I?

The celestial body that causes dogs to cry out is often depicted as the moon, especially during its fuller phases, as dogs and their wolf ancestors are known to howl, a behavior linked to long-distance communication. This same silent wanderer graces the night sky when most of the world is asleep, making its slow journey across the heavens while we rest.

Throughout history, many cultures have associated this luminous orb with human behavior, particularly episodes of madness. The very word "lunacy" derives from "luna," the Latin word for moon, reflecting an ancient belief that mental instability could be influenced by the moon's phases. While scientific studies have largely found no direct correlation between lunar cycles and human mental health, the enduring folklore highlights the powerful cultural impact this celestial neighbor has had on our perception of ourselves.

More than just a source of myth and nighttime light, this object is Earth's only permanent natural satellite, playing a crucial role in stabilizing our planet's wobble and influencing ocean tides with its gravitational pull. It is the fifth largest natural satellite in our solar system, always showing us the same face as it orbits our world.
