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 Bow Tree:
39.982200, -75.540200
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, Almanacs & Directories that were published in the late 1800's and early 1900's. Many of the Gazetteers include the distance from a community such as Bow Tree to various places of note, such as the White House.
With a nod to our favorite Gazetteers, the straight-line distance<1> beginning in Bow Tree and extending to:
Harrisburg, which is the State Capital of Pennsylvania, lies 73 miles [117.5 km]<1> to the west northwest (WNW). If you could drive a straight line from Bow Tree to Harrisburg, with an average speed<2>of 63 miles [101.4 km] per hour, it would take less than two hours to make the trip. A comfortable walk of 2.2 miles [3.5 km] per hour would take 5 days. A horse and buggy averaging 3.2 miles [5.1 km] per hour would take most of three days.
The White House (Washington, DC) is 109 miles [175.4 km] to the southwest (SW). Driving would take about two hours, a buggy would take 5 days and walking would take 7 days.
The shortest distance<3> to Jerusalem (specifically the Temple Mount and the Dome of the Rock) is 5,789 miles [9,316.5 km] and it lies to the northeast (NE).<4>
The distance to the Great Mosque of Mecca (specifically the Ka'bah - or Kaaba ) is 6,495 miles [10,452.7 km] and it lies to the east northeast (ENE).<5>
The distance to Saint Peter's Basilica (The Vatican) is 4,371 miles [7,034.4 km] and it lies to the east northeast (ENE).<6>'

Our distances are not driving distances, but are calculated as a '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- Bow Tree) 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 Bow Tree 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 Bow Tree. The point we use is located at these GPS coordinates - Latitude: 39.9822, Longitude: -75.5402 In this case, the coordinates for Bow Tree have been provided by the Geographic Names Information System (GNIS).
