The Earth is nearest the Sun on 3 January and farthest on 6 July, 147.1 and 152.1 million km. The nearest point creeps later through the calendar, one day in about 58 years; in 1246 it fell on the December solstice.

Run as nine dents that add, the planets turn the Earth’s nearest point 1162.5 arcseconds a century and shrink its stretch by 0.0000429 a century, against 1163.8 and 0.0000439 published. Jupiter does most of it.

The Sun’s centre wanders up to 1.48 million km, more than twice its own radius, but the Earth moves with it: measured from the Sun, the Earth’s nearest approach changes by 74,000 km from year to year.

In plain terms

The Earth’s path round the Sun is very nearly a circle, slightly stretched. It is closest in early January and farthest in early July, and the sunlight is a little stronger in January because of it. The seasons come from the tilt of the Earth, not the distance.

The stretched path slowly turns, and the other planets’ dents turn it — Jupiter most of all. A computer running the Sun and all the planets as dents that add gives the same turning that is measured, to within a fraction of a per cent.

The Sun is not fixed either. The big planets move it about, more than twice its own width. But the Earth moves with it, the way the Earth and the Moon move round the Sun together, so the Sun’s wandering hardly changes the distance between them.

What this memo does and does not do

It runs the Sun and all eight planets as summed dents, the method of E.4, and reads the Earth’s orbit off the run: the turning of its nearest point, the change in its stretch, and whether the Sun’s wandering centre matters.

The Earth’s axis wobble, which moves the calendar against the stars, is not modelled; its measured rate is used. The Moon is folded into the Earth.

1. The Earth’s Nearest Point

In 2026 the Earth was nearest the Sun on 3 January, at 147.1 million km, and farthest on 6 July, at 152.1 million km. At the nearest point 6.9 % more sunlight reaches the Earth than at the farthest. The seasons come from the tilt of the Earth’s axis, not from this distance: the Southern Hemisphere has its summer at the nearest point, the Northern its winter.

The date is not fixed. It can move a day or two either way from one year to the next, and over centuries it creeps later. In 1246 the nearest point fell on the December solstice; it now falls about two weeks after it.

2. Why The Date Drifts

Two turnings add. The Earth’s stretched orbit turns against the stars — the part the dents give, section 3. And the calendar is tied to the seasons, which move against the stars because the Earth’s axis wobbles like a top.

Near its nearest point the Earth moves about 3,670 arcseconds a day, so a shift of 61.9 a year moves the date one day in about 59 years. The published drift is one day in about 58.

3. Every Planet’s Dent

The Sun and the eight planets were run as nine dents that add, for a thousand years, from their positions at the start of 2000. Each planet was also run alone with the Sun and the Earth, to see its share.

4. The Stretch

The Earth’s eccentricity is 0.0167 now and shrinking, 0.0000429 a century in the run. Over long spans the planets’ dents swing it up and down: its largest cycle, 405,000 years, comes from Venus and Jupiter, and the total swing is about 0.063. When the stretch is larger the difference between January and July sunlight is larger.

5. The Sun’s Centre Wanders

The Sun is pushed by the planets’ dents as the planets are by its. Its centre circles the solar system’s balance point on a path set mostly by Jupiter and Saturn:

The circle is the Sun's own size. balance point the Sun’s own size Path of the Sun’s centre, fifty years. It strays up to 1.48 million km — 2.13 times its own radius. Jupiter’s and Saturn’s dents move it; the Earth moves with it.

Measured fromEarth’s nearest distance, change from year to year
The solar system’s balance point2.75 million km
The Sun’s centre74,000 km

The Earth moves with the Sun. Jupiter’s gradient at the Sun is 2.09 × 10−7 m/s²; at the Earth it differs from that by at most 1.11 × 10−7 — 1.9 parts in 100,000 of the Sun’s hold on the Earth. The shared part moves the Earth and the Sun together and does nothing to the distance between them. The difference is what turns the Earth’s nearest point, and it is already counted in section 3.

The Sun’s wandering is real and large. It does not change the Earth’s orbit about the Sun, for the same reason the Sun does not pull the Moon away from the Earth.

6. What This Settles, And What It Does Not

SettledThe dents give the Earth’s orbit

Summed dents give the turning of the Earth’s nearest point to within 0.2 % and the change in its stretch to within 2.5 %. The Sun’s wandering centre is shared by the Earth and does not change the distance between them.

Not modelled here

The axis wobble that moves the seasons, 50.3 arcseconds a year, is used as measured; it comes from the Sun and Moon acting on the Earth’s bulge.

The Moon. The run treats the Earth and Moon as one body at their balance point. The Earth’s centre circles that point at 4,671 km every month, one reason the date of the nearest point moves a day or two from year to year.

7. What The Dents Have Matched

This memo is one of four that test summed dents against measurement. Taken together:

MemoTested againstResult
1.12Newton’s law; the Moon’s fall, from its periodexact; within 0.008 %
5.20every classical term of the Moon’s motionwithin a few parts in a thousand
E.4Mercury’s perihelion, from the planets528.8″ against about 532″
E.4the remaining 43″, and Venus, the Earth and Marsone number, set on Mercury; the other three within 1–2 %
5.21the Earth’s perihelion turning and change in stretchwithin 0.2 % and 2.5 %

What the matches do and do not show

The summed dents are Newton’s arithmetic, so these matches confirm the dent method; they do not separate it from Newton’s law.

The steeper dent near the Sun has the same size as relativity’s correction, so perihelion measurements alone do not separate the Aether from curved space.

Starlight bending past the Sun, 1.75″, is not yet matched. It is where the two can first give different numbers — E.2 Eddington 1919.
