"Beware of Planet X / Nibiru"

(Credit to Tom Horn who mentioned this connection in a 2008 interview with Steve Quayle.)

Planet X aka Nibiru is typically described as a "Powerful Planet". 

If we were to translate "powerful planet" into Greek, we'd get "energia planet"

2Th 2:11
And for this cause God shall send them strong delusion, that they should believe a lie


The Greek for "Strong Delusion" is "energia plane".

πλανη plane {plan'-ay} from 4108 (as abstractly); TDNT - 6:228,857; n f AV - error 7, to deceive 1, deceit 1, delusion 1; 10 1) a wandering, a straying about 1a) one led astray from the right way, roams hither and thither 2) metaph. 2a) mental straying 2a1) error, wrong opinion relative to morals or religion 2b) error which shows itself in action, a wrong mode of acting 2c) error, that which leads into error, deceit or fraud

Thus a Planet is a wandering star, since it moves amongst the fixed stars in the sky.

Was Paul warming us that the strong delusion, or the lie involved a mythical, fictional 'powerful planet'? 

Does Nibiru really exist, or is it an alternative explanation for the Earthquakes and disasters occurring?

In studying the Sun, Moon, stars, planets, comets, etc., I'm not seeing any solid evidence of a large planet affecting our inner solar system.  In fact, the evidence suggests there cannot be such an object.

Ironically, the same Cornell University scientific paper that many (even Christians) claimed was proof of Planet X, specifically ruled out the existence of such a thing:
Actually, the values for its mass and distance needed to explain the empirically determined increase of the lunar eccentricity would be highly unrealistic and in contrast with the most recent viable theoretical scenarios for the existence of such a body. For example, a terrestrial-sized body should be located at just 30 au, while an object with the mass ofJupiter should be at 200 au. 
Thus, in conclusion, the issue of finding a satisfactorily explanation of the observed orbital anomaly of the Moon still remains open. Our analysis should have effectively restricted the field of possible explanations, indirectly pointing towards either nongravitational,mundane effects or some artifacts in the data processing. Further data analyses, hopefully performed by independent teams, should help in shedding further lighton such an astrometric anomaly.

Indeed, a wandering planet could indeed affect our world as described in Revelation and the Day of the Lord, but at this point, New Agers and secularists are more accepting of this energia planet than of judgements from God.   Which is completely consistent with 2 Thessalonians 2:11...

Be careful, while it is possible, and even likely, that there is a large undiscovered planet affecting the outer solar system, there is no evidence of it behaving as described by Planet X promoters.

All the heavenlies are in their places, as ordained by God:

Jeremiah 31:35-37

Thus says the LORD, Who gives the sun for a light by day, The ordinances of the moon and the stars for a light by night, Who disturbs the sea, And its waves roar (The LORD of hosts [is] His name)

If those ordinances depart from before Me, says the LORD, [Then] the seed of Israel shall also cease from being a nation before Me forever.

Thus says the LORD: "If heaven above can be measured, And the foundations of the earth searched out beneath, I will also cast off all the seed of Israel For all that they have done, says the LORD.

The word for ordinances is Strongs 2706:
from 'chaqaq' (2710); an enactment; hence, an appointment (of time, space, quantity, labor or usage):--appointed, bound, commandment, convenient, custom, decree(-d), due, law, measure, X necessary, ordinance(- nary), portion, set time, statute, task.
So, God is saying that if the prescribed paths of the sun, moon and stars were to be abandoned, so would He abandon Israel.

Will God abandon Israel? Of course not! The Abrahamic covenant is about to be fulfilled as promised some 4,000 years ago!

Also consider that if angels are also called stars (defined in Revelation), then a wandering [from the truth] star is a fallen angel, right?

Re-read 2Th 2:11 with "Powerful fallen-angel" instead of "strong delusion".  Did that click into place for you?  It did for me:

2Th 2:11 And for this cause God shall send them powerful fallen-angel, that they should believe a lie

Which is biblically consistent with:

Rev 12:9
And the great dragon was cast out, that old serpent, called the Devil, and Satan, which deceiveth the whole world: he was cast out into the earth, and his angels were cast out with him.

God will shake the Earth, He said so, but He doesn't have to give a physical explanation or means to do it with.

Planet X could just be a lie.  A viral meme, a plausible alternative explanation to the return of Christ. 

Do we want to be part of spreading this strong delusion? 

Be careful, for even the elect will be deceived, if it were possible...
