A video of a mystery orb spotted hovering above the sun has gone viral as viewers have been speculating wildly about its origin.
Melissa Huffman captured the footage at the Sanibel causeway in Florida.
The footage has had more than 87,900 views since it was uploaded to YouTube on October 19.
Melissa claims she was with a friend at the time, who also saw the mystery orb.
She wrote in a YouTube comment: "I was on Sanibel causeway, little rock, and I did freak out.
"I have been studying the sky. It's strange."
Theories about the strange light have ranged from the Nibiru cataclysm to a burning red dwarf star.
Another viewer added: "If I saw this in person, I would freak out.
"I have watched the sky for decades: telescopes, cameras, binoculars.
"NEVER has there been anything that size/scale next to the sun! This is NOT Venus or Saturn..and most definitely not a lens flare."
Others disagreed, with one person commenting: "It's a reflection of the sun in the upper atmosphere. Almost like a mirage. It's not very common but loads of video evidence exists."
