Self-styled Nibiru expert and film producer Yuval Ovadia said the strange image was tangible evidence of Nibiru or Planet X.
In the disclosure yesterday he even went further and blasted other Nibiru truth seekers attempts at proving the myth, saying most footage or images revealed by them so far were fake or inaccurate.
The Nibiru or Planet X theory is that a mini solar system consisting of a sun, planets and moons is lurking on the edge of our solar system with a huge orbit of the sun.
Nibiru believers are convinced the "rogue system" is making its way from the outer solar system inwards, where it will wreak havoc on Earth as it passes at about four million miles away.
They say the planet will cause the poles to switch, sparking great earthquakes and volcanic eruptions.

Leaked still of the Planet X system on its approach, caught by infrared camera
Believers now claim it will be on an approach path with the earth between November 20 and December 20.
With approach dates from September and October already coming and going, most people are reassured it is just a hoax.
However, Mr Ovadia insisted the danger is real and says this short clip is genuine evidence of the mythical system.
Italian Scott Brando is a paranormal debunker, who forensically examines images and videos released his verdict on website ufoofinterest.org.
He analysed the video released by Mr Ovadia and ridiculed his claims.
Mr Brando said the bright object was nothing more than a standard plane's contrails being backlit by the sun.
He tweeted his view with a GIF video showing a contrail being lit from behind with the same deep orange colour.
He said: "Well of course we are just seeing a contrail at sunset like this."Related articles
It is not the first time a sunlit plane contrail photograph has been put forward as evidence of something it is not, such as a UFO, or meteor entering earth, and Mr Brando and others have previously debunked these.
It appears Mr Brando is not alone in his conclusion.
Several people took to twitter to round on Mr Ovadia.
Robert Lockwood tweeted: "Also debunked as being just a plane."
A Twitter user with the name Joe Sixpack added: "Even more chilling! See how it disguises itself to look EXACTLY like an airplane contrail?! Sneaky #NIBIRU!"
Karl Stankiewicz said: "Seen these since childhood. Contrails around sunset show up like this depending on angle of view."
Steven Callaghan tweeted: "That's a fast moving mini system... Good grief."
Scores of videos and images which have been alleged to show Nibiru have already been posted online and later debunked as nothing more than lens flares from the camera or reflections.
