Comet Swift-Tuttle is a large comet that orbits the Sun approximately every 133 years. Discovered in 1862 by Lewis Swift and Hugh Tuttle, it is known for its bright tail and impressive size, making it one of the most significant comets in our solar system. Its orbit takes it far beyond the planets, but it comes close to Earth during its journey. As it approaches the Sun, the heat causes the comet's icy nucleus to release gas and dust, creating a glowing coma and a spectacular tail. Comet Swift-Tuttle is also the parent body of the Perseid meteor shower, which occurs every August when Earth passes through the debris left behind by the comet.
