Short-period comets are celestial objects that orbit the Sun in less than 200 years. They originate mainly from the Kuiper Belt, a region of icy bodies beyond the orbit of Neptune. These comets are often easier to observe from Earth due to their relatively quick orbits. As they approach the Sun, short-period comets develop bright comas and tails made of gas and dust. Famous examples include Halley's Comet, which returns approximately every 76 years, and Swift-Tuttle, which has a period of about 133 years. Their predictable paths make them significant for astronomical studies.
