Date of sighting: September 15, 2011
Location of sighting: Earth's Sun

NASA has yet to address what these UFOs orbiting the sun are or why they are the size of Earth yet move at such high speeds. The objects change position around the sun, orbiting it yet do not burn up, do not glow from heat and do no leave a tail of buying debris. Look at on close up that looks like an earth size grey metal orb.
