According to a ufologist, the European Space Agency (ESA) might be keeping in secret a gigantic 62- mile alien space station stationed in the deep space near Lutetia, an asteroid located in the asteroid belt between Mars and Jupiter.
Lutetia was discovered in 1952 by Hermann Goldschmidt. On July 10, 2010, ESA’s space probe Rosetta passed near Lutetia, being the first M-Type asteroid to be visited by a space probe.
This asteroid is a vestige of the primordial planetesimals, that formed all the planets of the solar system more than 4 billion years ago
The Rosetta eventually discovered that huge unknown object that, according to conspirators, is an alien station. If you want more details about this, take a look at the following video.
