Planet X

You're reading an English translation of the original Czech page.

Laplace’s synchronization of the Jupiter sattelites Io-Europa-Ganymed gives to believe, that also planets can be synchronized some way.
But principle of minimal interaction action that was developed by Michael William Ovenden (1926-1987), does not apply for outer planets.
So:

Long-term changes in solar activity has not yet been sufficiently explored or explained. The cause may be some resonance with a longer period arising in the solar system, but one can not completely eliminate the influence of some remote planet X.

See also: The influence of planets on solar activity.

Behind the periphery of observed solar system there still can reside bodies that in fundamental way influence on run of the known system and stay hidden.

Even relatively small bodies can – due to large distance – notably deflect barycentre of the system and so influence on motion of other bodies, solar activity and so on.

See also: Shape functions.

Estimated periods

During last two centuries large scale of estimations for possible planet X was done.  The estimations usually come from computations of orbital perturbations of outer planets or comets.

Kuiper belt

Kuiper belt (30-100 AU) of asteriods (so called KBO objects) can be divided into two parts - inner 32-36 AU (180-220 years) and outer 42-46 AU (270-320 years).

Behind boundary 100 AU no object was found.

Adrian Brunini and Mario Melita tried to make this phenomenon clear (y.2002, with help of computer simulation) by existence of planet X (size of Mars) in distance c. 60 AU (see so called Kuiper cliff, i.e. marked  decrease of number of bodies in range 44-50 AU). According to Jackson and Killlen there certainly does not exist planet with mass exceeding 5 MEarth in band 40-75 AU (otherwise it appeared in perturbations of Neptune.). It is assumed that comet 2000 CR105 (observed in distance 53 AU)  is exposed to gravitational influence of unknown body  (size of  Moon or Mars, in distance c. 66 AU).

Patterns

In some planetary configurations position of possible planet X can be estimated.

E.g. the line of planetary alignment in eyars 719.29, 1147.48, 1575.66 (see Planetary patterns) slowly rotates with period approximately 4420 years.

During synodical period J-U the line J-U rotates by c. 59.189˚, i.e. after B= 428.18 years by 34.884˚.

Complete orbits is hence B* 360˚/34.884˚ = 4418.8 years.

Because angle of synchronization ω need not to be only 0˚, also other periods can be deduced:

Configurations

Let us try to smooth planetary patterns of years 719.29, 1147.48, 1575.66 by circular orbit with approximately 390 year period.

Computation (according to Bretagnon heliocentric VSOP82) gives period 387.3 years (with longitude c. 157.3˚ for epoch 2451543.5), i.e. orbit at c. 53 AU (53.1 AU-53.2 AU).

Such planet X would have in observed configurations the following longitudes Lx:

Pickering’s planet?

s_X19300101

American astronomer William Henry Pickering (1858-1938) predicted in the y.1908 planet with period 373 years (51.9 AU, longitude 105˚). Later (1919) he modified its period to 409.1 years. Pluto was in the year 1930 observed at longitude 108.5˚, longitude of Pickering planet for year 1930 was 102.6˚ (longitude computed by Percival Lowell was 102.7˚), see Hypotetical planets (Paul Schlytter).

Our planet X with period 387.3 would be 1930,00(1929 Dec 29) at longitude c. 92.8˚

(LJ:72,8 ˚,LS:274,8˚, LU:17,9 ˚,LN:152,3˚, LX: 92,2 ˚), i.e. only c. 10˚ from position computed by Pickering and Lowel.

Could be the Pickering planet (in the shadows of Pluton) overlooked?

Minimal interaction

Because X/N ~ 7/3 resp. X/U ~ 14/3 positions repeats after 7 resp. 14 configurations.

When X pass near Uranus, Uranus is in perihelion, e.g. in year 1630 ( => beginning of Maunder minimum?) When X pass near Neptune, Neptune is in perihelion, e.g. in year 1879 ( àbeginning of descent to minimum?)

Planetary patterns

Division into 7 parts lead in case of period X=387.3 years to value X/7 = 55.33 years, i.e.. c. half of period 110.5 years,  see Solar cycles.

Resonance with outer planets

For synodical periods the following relations approximately holds.

a/ 3-bodies

for (N,X) = 286.77 years (~24J) a (U,N)=171.44 years:   

 (U,N) :(N,X) =3:5 

Hence resonance 3/U–8/N+5/X = 0; it holds exactly for period X=389.2 years. 

for (N,X) = 286.77 years (~24J) a (S,N)= 35.87 years (~3J, Bruckner’s period): 

 (S,N) :(N,X) =1:8 

Hence resonance 1/S–9/N+8/X = 0; it holds exactly for period X=387.0 years.

b/ 4-bodies

for (U,X) = 107.30 years a (S,N)=35.87 years:   

 (S,N) :(U,X) =1:3 (R1) 

Hence resonance 1/S–3/U –1/N+3/X = 0; it holds exactly for period X=383.3 years.

for (S,X) = 31.88 years a (J,N)=12.78 years: 

 (J,N) :(S,X): =2:5 (R2) 

Hence resonance 2/J–5/S –2/N+5/X = 0; it holds exactly for period X=376.8 years.

Period of resonance R2 works out as very low, but resonance – in period, for that reliable observation of Neptune exists – is relatively well satisfied  in longitudes of planets:

Specification of position

Values of resonances computed according to relations 3/U–8/N+5/X = 0 and 1/S–9/N+8/X = 0 differ from values based on circular orbit of the planet.

Departures will be computed according to relations:

 ∆LX(U,N) = - (5*X-8*N+3*U)/5 

 ∆LX(S,N) = - (8*X-9*N+1*S)/8

(I.e. 3*LU –8*LN +5*Lx  = 3*356˚ –8*326˚ +5*164˚ ~ 0˚, resp.1*LS –9*LN +8*Lx  = 1*178˚ –9*326˚ +8*164˚ ~ 0˚)

Jupiter resonance with planet X?

Saturn-Neptune pair seems to be synchronized with pair Uranus-X, see Jupiter.

Hence higher extremes at interval of 3 Bruckner’s period (c. 107-108 years) would follows.

E.g. analysis of wood from ancient Greece c. (-600,-400)  showed  2 maxima in distance 108 years (Mariolopoulos,1962)

Planet X and solar activity

Solar activity

We will try to observe possible influence of hypothetical planet X on solar activity - with help of theory of barycentric deflection (see Solar activity

Planet X with c. 390 year period  would influence planets Uranus and Neptune with c. 856 years period, i.e. 2B (see Babylonian period).   Synodical period of Uranus and Neptune with regard to body with c. 390 year period makes approximately: (U,X) = 107 years, (N,X) = 285 years in ratio 3:8 with common period 856 years=2B.  (Similarly e.g. for period 717 years , where (U,X) = 95 years, (N,X) = 214 years, we get ratio 4:9 with common period also 2B).

The dependence is approximated by function:

cos(2π*(x-2027)/286.8)+cos(2π*(x-2005)/107.3)+cos(2π *(x-1907)/171.4),

where 286.8=(N,X), 107.3=(U,X), 171.4=(U,N).

Influence U-N is draw in black, influence U-X in light blue and influence N-X in blue color.

Total influence in marked in red:

Planet X and Mayans

Mayan planet?

Period of 390 years (see above) corresponds approximately to Mayan period Baktun 394.24 years (144000 days).

Babylonian patterns - Similar configurations

We will observe configuration that satisfy the following conditions:

Jupiter near its perihelion Jupiter in opposition to Saturn Mars in opposition to Earth

We get dates:

302,80  J:  5,96 S:196,10 U:247,41 N:196,60 H: 19,76  302 Oct 17 AD

Hypothetical planet X is here always near to opposition to U and N - so these configurations will appear in periods of higher solar activity (see Planet X and solar activity).

Now let us change the second condition to:

Jupiter in conjunction to Saturn

We get dates:

Extrapolation

Observed configurations step with Babylonian period. Twelve of such periods cover interval c. 5125 years:

-3113.81, -2886.73, -2259.66, -1832.59, -1405.51, -978.44,
 -551.36, -124.29, 302.80, 729.86, 1156.94, 1583.98, 2011.08

And the beginning and ending dates roughly make boundary of Mayan calendar according to GMT-correlation (3113 BC-2012 AD).
