Siderophobia

We played in The Queen's Arms pub quiz and won last night. One of the questions was to guess what 'siderophobia' meant. Jack accurately proposed that it was the fear of stars. As Wikipedia explains:

A sidereal day is approximately 23 hours, 56 minutes, 4.091 seconds (23.93447 hours or 0.99726957 SI days), corresponding to the time it takes for the Earth to complete one rotation relative to the vernal equinox.

Fair enough, but I thought it a strange thing to be afraid of... until I looked out my window just now at the night. Does no one else find it terrifying that we're spinning around on a lump of rock just about large enough to make itself spherical in an impartial vacuum where the lights keep going out with arguably no instructions except those we've cobbled together ourselves, passing the time however best we can? Maybe it's not so ridiculous to be afraid of the stars.

At least the multiverse might be measurable.
