I did a lot of research trying to find the history and background of the alleged astronomer "Leonid Elenin" but could find barely anything about him.

Seems like a very weak profile here:

LEONID = Meteor Shower
[link to en.wikipedia.org]

ELE = Extinction Level Event
[link to en.wikipedia.org]

NIN = "Person" in Japanese
[link to en.wiktionary.org]

Deep Impact (the movie) - about an E.L.E (extinction level event), an asteroid hitting earth

In the movie, president was 1/2 black 1/2 white (Morgan Freeman) - we have President Obama

In the movie, kid who discovered the comet named LEO Biederman, a Russian name. Leonid Elenin is Russian.

Both discoverers in reality and in Deep Impact are born in January

Both comets in reality and the movie are discovered on a 10th day of the month - May 10, 1999 and December 10, 2010. That's 11 years apart. Its 2011

The movie stared ELIjah Wood (has the word NINe tattooed on his body) and Tea LEOni (the 8299 Tealeoni asteroid is named after her, Deep Impact was her NINth film)

You know the way TPTB operate. Everything is scripted well in advance and they use Hollywood to drop clues.

DOOMSDAY IS ON BABY!
