Halley's Comet heading to Chicago
Name: Megan McCormack
When is the next time and how often does Haley's Comet pass over Chicago?
Halley's Comet (note spelling) has a period of 76 years. It last appeared
in 1986. Hopefully, when it "passes over" Chicago, it will also pass over
the rest of the Earth.
By the way, the pronunciation of Sir Edmund Halley's last name is the same
as mine: the "a" is pronounced as in "hall" although for many years it was
common to hear it pronounced as in "hail".
