Actually, many sources have taken note of it and have seen it and or posted pics, vids. etc....yet it does stand to reason that the governments of the world, religious overlords, NASA etc. would keep it hidden as long as possible so as to keep society from breaking down....also thing to note and where there is smoke there is fire...
a. The rich and governments are building bunkers in mass.....WHY?
b. Governments are stock piling food, meds. etc.....WHY?
c. History is replete with examples of a tenth massive planet in granite and stone pictures etc.
LUKE does say people will look up with heart failing for fear of those things that are coming upon the earth
Revelation does say men hid in dens, caves etc....the word DENS is something prepared like a bunker...
