A fun thing to do when stargazing is to look at your "birthday star."
Your birthday star is a star whose light left on the long journey to Earth the year you were born.
Of course, your birthday star changes each year.
Being 37, my birthday star this year is Arcturus.
Last year, it was Denebola and next year it will be Lambda Ser.
Here's a fun chart to look up your star.
I'd imagine that if you're having a stargazing party, breaking out the Birthday Star Chart and letting everyone see "their" star would be a humongous hit.
