man has proposed to his fiancée during  event that occurs just once every 6,800 years or so - give or take  decade or two. John Nicotera, 33, popped  question to his now affianced Erica Pendrak, 26, while the Neowise comet passed over their heads. It will be another seven millennia before anyone else can get down on one knee and propose while  celestial body flies overhead. Mr Nicotera is  space buff. He knew the rare astronomical event would take place in  Northern Hemisphere for  limited time and planned his proposal to coincide with the comet being visible in  night sky. The couple drove to  campsite outside New York last week and John waited for the comet to appear.
Ms Pendrak immediately accepted Mr Nicotera's proposal. She told reporters that she knew her fiancé was taking her to see  once-in--lifetime event. She said she got  surprise of her life when he dropped down to one knee. She said: "I was just completely shocked - tears and everything. I felt instant chills and pure happiness."  photographer friend went to  campsite with the couple to capture  proposal with the comet whizzing by across  heavens. John and Erica are both teachers who like experiencing historical events together. John said: "Every single star was out. It was too special to let it go. I thought, 'I'm massively in love with this girl. I'm going to do it.'"
