Virtual encounter: far of Mars' orbit at 12.5 light-minutes from Earth, the comet Garradd shines with 7 magnitude and shows your wide dust tail that opens in fan behind, and your long and stretched ion tail that extends toward right (barely visible into image). At left and in the end of our galaxy, at 5.000 light-years away, the globular cluster M92 contains thousand old stars, wich together shine in our sky with 6 magnitude, more than the comet infinitely near.
