A Cloaked Alien Spaceship Orbiting Mercury?

NASA's spaceship observed  a massive alien spacecraft orbiting tiny planet next to Mercury. It was seen while NASA was on a mission for watching "Coronal Mass Ejection" from the sun.

It is "definitely some sort of manufactured object.", said the person who had used US Navy's SECCHI website to gather the images.
"It's cylindrical on either side, has a shape in the middle... It definitely looks like a ship to me. Very obviously it's cloaked," he continued.
"There's really, absolutely no other explanation for that than some sort of ship."
