I had this theory that meteor showers named after constellations (e.g. the Leonids) happen about 3 months after the corresponding "star sign" month when the Sun appears in that constellation.  It seems it's half-right and applies when Earth plows directly into the meteors, but some come in from the side and have different offsets like 6 months.  In any case a 0 month offset would be strange because it would be hard to see meteors coming from the direction of the Sun.   #space #astronomy
