In response to anomalous SECCHI images:
The only thing any of us can do at this point is assume, since the agencies entrusted with tracking objects such as this are not exactly being forthcoming, especially considering the billions of tax payer dollars they use to fund these projects, ostensibly in an effort to "save humanity" (as if it is worth saving). This object (Hercolobus, Nibiru, Nemesis, The Destroyer, Planet X, Wormwood, et. al) could be responsible for the influx of comets (ISON, Encke, et. al.) arriving in our solar system from the Oort Cloud as it passes through.
As to the validity of these images, I cannot say for sure if they are genuine or just another anomaly, but there certainly have been a great many "anomalies" being viewed over the past several years.
My theory is that there certainly is "something" out there influencing the Earth in a negative way. Whatever it is, is not only altering the climate and geology of the planet, but this is also manifesting itself on the geopolitical and socioeconomic fronts. It is also affecting human behavior and health, which, in case you hadn't noticed, is off the charts. Even the animals are losing it. The list of things powerful enough to influence all of these different aspects of terrestrial life is extremely short.
There might be three things on this list. One would certainly be the Sun. As the sun is responsible for all of life on this planet, it stands to reason it could also be the cause of the death of the planet. The other would be an extra-solar system object such as the one being discussed here.
Whatever the truth is, we live in fascinating times...
