Three glowstick green comets, all discovered this year, could make a spectacular naked-eye appearance this month. The chances of seeing a meteor are good because there are two overlapping meteor showers, the Orionids and Draconids. The comet may also produce a faint meteor shower in its wake around Oct. 5. Meteor showers are not as elusive as comets, but they still require patience, a dark sky and some luck to see. Meteor showers occur when the Earth passes through the debris left behind by a comet or asteroid.
