Nibiru at 2075 or 2085?

Without merging the theory of Nibiru into the year of 2012, which has nothing to do with Nibiru predictions & merely a Mayan calendar ending. Also, without mixing Zecharia Sitchin’s theory with other individuals certain claiming of Nibiru’s approach to Earth at other years. Can a planet or brown dwarf star be detected that presumably by Sitchin is coming by or near 2085? Given the round about year, can one measure an idea to its distance from our solar system? Might that increase the chances, what ever Nibiru might be, of detecting if it actually exists? What “name(s)” of other anthropologist or paleographers or person with expertise able to decipher Sumerian writing reject to Sitchin’s theory on Nibiru?
