Hi Michael,
Sorry to disagree with the experts who have commented, but you have undoubtedly captured an image of Nibiru (Planet X) here mate -- well done!

I've seen hundreds of images of it over the last few years and yours is undoubtedly the same "object". Though NASA and the governments of the world Nibiu are involved in a massive conspiracy to cover it up and hide the evidence, Nibiru will throw the inner solar-system into chaos in just over two years time as it sweeps toward the inner-planets and will cause the Earth to pole-flip and more than 75% of the population will perish in the disaster in December 2012. This was all supposed to happen in May 2003 but for some reason, the aliens put the whole shebang off until 2012.
Yeah, right.
It's a lens flare -- pure and simple. It is the same as 10s of 1000's of other purported photos of Nibiru near the Sun. They are, almost without exception, all lens-flares (an internal reflection within the lens system of your camera when pointed very close to straight-at a very bright object). There are a few others that (while not "Nibiru") are a photo of a Sun-dog or parhelia -- a natural phenomenon caused by Ice-crystals in the Earth's upper atmosphere. Nothing to get excited about or worry over in either case.
Best and welcome to IIS,
