The sky has more stars than a beach has sand.
If you assume a grain of sand has an average size and you calculate how many grains are in a teaspoon and then multiply by all the beaches and deserts in the world, the Earth has roughly (and we're speaking very roughly here) 7.5 x 1018 grains of sand, or seven quintillion, five hundred quadrillion grains. If we have a Hubble telescope and a calculator, we can count distant galaxies, faint stars, red dwarfs, everything ever recorded in the sky. The population of stars jumps enormously, to 70 thousand million, million, million stars in the observable universe (a 2003 estimate), so that we've got multiple stars for every grain of sand.
