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.
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.

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).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:
Number | Angle ω | Period B*360˚/(ω+34.88˚) | Orbit | ? Planet X ? |

Values derived just from positions of planets Jupiter and Uranus fit also exactly the period of Neptune.

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).

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?
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?)Uranus near perihelion:

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.
For synodical periods the following relations approximately holds.
a/ 3-bodies
for (N,X) = 286.77 years (~24J) a (U,N)=171.44 years: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):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: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: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:

Hence (assuming respecting of resonances) e.g. in y.2010 planet would be expected at longitude 163.8˚÷164.2˚ (instead of 166.6˚), i.e. c. 164.4˚± 0.2˚.
(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.

Similarly as there exists occupied orbits in front of Jupiter (see Action of Jupiter) in ratio q=A/N =2/3 (Hilda) and q= 3/4 (Thule), we expect occupied orbits also
in front of planet X having the same ratios. From span X= 380-400 years we get:

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:
Comparison with graph derived from shifts of conjunctions J-S with regard to U-N (see Babylonian period ).
Each graph cover approximately 856 years period.

We will observe configuration that satisfy the following conditions:
Jupiter near its perihelion Jupiter in opposition to Saturn Mars in opposition to EarthWe get dates:
302,80 J: 5,96 S:196,10 U:247,41 N:196,60 H: 19,76 302 Oct 17 AD
1156,94 J: 8,12 S:193,94 U:305,10 N:262,28 H: 93,68 1156 Dec 2 AD
2011,08 J: 10,01 S:191,54 U:359,83 N:328,12 H:167,60 2011 Jan 28 AD
17.10.302 2.12.1156 28.1.2011
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 SaturnWe get dates:
-124.29 J: 5,20 S: 1,57 U:216,57 N:341,70 H:342,79 126 Sep 19 BC
729.86 J: 7,13 S: 0,28 U:276,89 N: 49,40 H: 56,71 729 Nov 4 AD
1583.98 J: 8,03 S:358,95 U:332,33 N:116,87 H:130,61 1583 Dec 21 AD
4.11.729 21.12.1583
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).
