Your lifetime as a cosmic odometer: how far you've traveled through space
A novelty website called the Cosmic Odometer estimates how far you’ve traveled through space by using your birth date, claiming, for example, that someone born in 1990 has orbited the Sun over 21 billion miles and moved through the solar system about 155 billion miles. The piece also explains the Helix Nebula as a planetary nebula studied by NASA’s Spitzer Space Telescope, illustrating how dying stars shed their outer layers and reveal remnants like a white dwarf and dust disks.
