There’s a meme going around Twitter called #ZodiacFacts, mostly random astrological statements. I figured I’d post some actual, y’know, facts about the Zodiac.

  • The Zodiac is the set of constellations through which the sun, moon and planets appear to move when seen from Earth.
  • In a dark sky, away from light pollution, you can sometimes see Zodiacal light after the sun has set.
  • Due to cycles in Earth’s orbit, the present-day constellations of the zodiac no longer line up with those used by astrology.
  • In a REALLY dark sky, you can see the Gegenshein: sunlight reflecting off of interplanetary dust.
