Jamestown astrocartography
Jamestown sits at 15.94°S, 5.7°W — inside the tropics, where the sun passes directly overhead twice a year and the seasons are told by rain rather than by light. Which of your planetary lines fall near it, and how closely, depends entirely on when and where you were born.
Which of your lines reach Jamestown?
⚠️ A place has no fixed character
Any page telling you Jamestown is universally a “Jupiter city” is describing something that does not exist. The lines that cross it are different for every person born. The reading below is the only way to know which of yours reach here.
Do any of your lines reach Jamestown?
Three things, and the reading is yours. No account, no email, nothing kept.
What Jamestown’s position does to a reading
Astrocartography is geometry before it is anything else, so where a city sits changes how it behaves. These are facts about Jamestown rather than about you — they hold whoever is reading.
How close is close, here
Distances here are measured as real ground: one degree of orb is 111 km, the same width everywhere on earth. Jamestown sits close enough to the equator that a degree of longitude is also about 107 km, so our figures and those of older software that measures overhead lines in longitude will agree closely.
Every line can reach this latitude
A rising or setting line is a horizon curve, and it exists only where the body actually crosses the horizon. At 15.94°S that means a body within 74.1° of the celestial equator. All ten bodies stay inside that, so every one of the forty lines can pass through Jamestown’s latitude. Nothing here is ruled out by geometry — only by your own chart.
The same geometry, in daylight
The equation behind a rising line is the equation behind sunrise, so you can watch it work. At the summer solstice Jamestown gets about 11 hours 3 minutes of daylight, and at the winter solstice about 12 hours 57 minutes. The further a place sits from the equator, the steeper that swing — and the more slanted its horizon lines run.
The clock against the sun
Overhead and underfoot lines are meridians — they depend on longitude, not on what a clock happens to show. Jamestown’s clocks run 23 minutes ahead of its own sun on standard time, so the instant a planet actually crosses this meridian is not the instant local midday suggests. Any planet standing overhead here has its opposite line running down the far meridian at 174.3°E, half a world away.
Places near Jamestown
All cities →Nothing else in the gazetteer sits within a degree of orb of Jamestown, so a line that misses here misses on its own. These are the nearest places to weigh it against.

Common questions about Jamestown
Which planetary lines run through Jamestown?
That depends on the day, hour, and place you were born — lines are personal, and two people born days apart can have completely different ones crossing Jamestown. Enter your birth details on this page to see which of yours pass nearby and how close they run.
Is Jamestown a good place to live?
There is no universally good or difficult city. Jamestown will hold some kinds of work and make others harder, depending on which of your lines reach it and how closely. Every line offers something and asks something in return, and we show both halves.
How close does a line have to be to Jamestown to count?
We measure the distance from the city to the line as real ground — about 111 km to the degree, the same everywhere on earth. Inside roughly half a degree is a direct hit; out to about two degrees still reads. Because a degree of longitude at Jamestown's latitude is only about 107 km, older software that measures overhead lines in longitude will quote a different figure for the same city.
Can every planetary line reach Jamestown?
Yes. At 15.94°S every one of the ten bodies rises and sets, so all forty lines can pass through this latitude. Whether any of yours actually do is a question only your own chart answers.
Where exactly is Jamestown?
Jamestown sits at -15.9387° latitude, -5.7168° longitude, keeping Atlantic/St_Helena time, with a population of about 629. Those coordinates are the point every line distance on this page is measured from.
What if none of my lines are near Jamestown?
Then we say so and leave it there. Most of the world is quiet ground for most charts, and a reading that finds something meaningful in every city on earth is not telling you anything. Quiet ground is not bad ground — it simply asks less of you.
