Whether using binoculars, a small telescope or the naked-eye, the Heavens-Above
website can help you to find your way around the night-time sky. In addition to detailed
sky charts, their website will help you find planets, asteriods, comets, satellites and their tracks across the sky.
To give accurate results, Heavens-Above requires the latitude and longitude of your location. As a starting point, when we link to Heavens-Above,
we pass this GPS location for Tisonia:
30.534404, -81.621208
Once you're on the Heavens-Above website, you can improve its accuracy by giving a more precise longitude and latitude as your actual position.
As we travel, we always see a community with a name that gives pause. While there are names which are interesting or familiar, some catch our attention or strike our fancy. We always wonder about such a name. If time permits and the community is not too far, we'll usually try to make a side-trip.
We spend a lot of time looking through Gazetteers that were published in the late 1800's and early 1900's. Many of the Gazetteers include the distance from a community such as Tisonia to various places of note, such as the White House.
With a nod to our favorite Gazetteers, the straight-line distance<1> beginning in Tisonia and extending to:
Jacksonville, which is the Seat of Duval County, lies 13 miles [20.9 km]<1> to the south southwest. If you could walk a straight line from Tisonia to Jacksonville, with an average speed<2> of 2.2 miles [3.5 km] per hour, it would take 6 hours to make the trip. A horse and buggy averaging 3.2 miles [5.1 km] per hour would take four to five hours.
Tallahassee, which is the State Capital of Florida, lies 158 miles [254.3 km] to the west (W). Driving, with an average speed of 63 miles [101.4 km] per hour, would take less than three hours, a buggy would take 7 days and walking would take 9 days.
The White House (Washington, DC) is 633 miles [1,018.7 km] to the north northeast (NNE). Driving would take just over a day, a buggy would take 25 days and walking would take 36 days.
The shortest distance<3> to Jerusalem (specifically the Temple Mount and the Dome of the Rock) is 6,464 miles [10,402.8 km] and it lies to the northeast (NE).<4>
The distance to the Great Mosque of Mecca (specifically the Ka'bah - or Kaaba ) is 7,143 miles [11,495.5 km] and it lies to the northeast (NE).<5>
The distance to Saint Peter's Basilica (The Vatican) is 5,034 miles [8,101.4 km] and it lies to the northeast (NE).<6>'

<1>
Our distances are not driving distances, but are calculated as a 'straight-line' (or point-to-point) distance. A straight line distance ignores things like rivers, canyons, lakes, et cetera - it's truly a line from Point A (ie- Tisonia) to Point B. In other words: 'As the crow flies'.
<2>
While we have tried to pick reasonable speeds, the rate of travel is very theoretical - obstacles like fences, hills, lakes, river crossings and rest stops have been ignored. When we say 'Days' of travel, we're assuming 8 hours of travel per day.
<3>
The shortest line can be visualized by stretching a string on a Globe from Point A to Point B - this is known as a Great Circle Route. Where you might expect the shortest route from Tisonia to the Middle East to be East and South, the Great Circle Route actually lies to the North and East.Our distance measurements begin at a specific point in Tisonia. The point we use is located at these GPS coordinates - Latitude: 30.5344, Longitude: -81.6212 In this case, the coordinates for Tisonia have been provided by the Geographic Names Information System (GNIS).
