When Earth passes through the comet's debris, the "comet crumbs" heat up as they enterEarth's atmosphereand produce impressive "shooting stars" that streak across the sky. 55P/Tempel-Tuttle is a small comet with a nucleus measuring just 2.24 miles (3.6 km) across. It was discovered indepe...
"To obtain an idea of the size of a light-year, take the circumference of the Earth (24,900 miles), lay it out in a straight line, multiply the length of the line by 7.5 (the corresponding distance is one light-second), then place 31.6 million similar lines end to end," NASA's ...
