Kermillian's Comet

Kermillian's Comet is a comet named after famed ancient Danville astronomer Augustus Kermillian, who discovered the comet during a flight past earth. Like the famous Halley's Comet, it is what's known as a periodic comet, meaning that scientists know when the comet will be visible in the sky again. In Kermillian's Comet's case, it comes around every 73 and half years.

During its most recent orbit, stepbrothers Phineas Flynn and Ferb Fletcher built a giant observatory in their backyard for their friends to observe the comet. They put on a laser light show and for their grand finale, they used the laser to carve their faces into the face of the comet in order to show their grandchildren the next time the comet came around. Their show was interrupted when Dr. Heinz Doofenshmirtz's heat ray destroyed the observatory.

Legend has it that if you make a wish while the comet is visible, it will come true. During the comet's most recent orbit, many of the wishes of the Danville residents who attended Linda Flynn and Lawrence Fletcher's comet-watching party had their wishes come true, including steaks falling from the sky and Candace Flynn getting closer to her crush Jeremy Johnson.

 * Due to the odd clothing worn by Augustus Kermillian in Lawrence's History of Danville book, it seems that Kermillian's discovery of the comet may pre-date the 1758 discovery of Halley's Comet.
