Mataura
French Polynesia
Mataura is the closest city to Rosetta's antipodal point (892 km).
The antipodal city to Rosetta is Mataura. This means that, among all the populated locations in the world, the farthest city from Rosetta is Mataura.
The distance from Rosetta to Mataura is about 19,000 kilometers. A direct flight would take around 21 hours, but there aren't commercial routes between these cities.

How to calculate the antipodal point?
The antipode can be calculated by understanding the geographic coordinates and applying simple formulas. We will use the following variables:
- LatO: Latitude at the origin point.
- LngO: Longitude at the origin point.
- LatA: Latitude at the antipodal point.
- LngA: Longitude at the antipodal point.
Step 1: Obtain the geographic coordinates of Rosetta
The DMS coordinates are: 31°23'58.2'' N 30°25'1.8'' E .
Calculations are easier by using the decimal format, hence:
LatO = 31.39951°
LngO = 30.41718°
Step 2: Calculate the latitude
LatA = - LatO = -31.39951°
Since the latitude is positive (north direction), the antipode must be negative (south direction).
Step 3: Calculate the longitude
LngA = LngO ± 180° = 30.41718 - 180° = -149.58282°
Since the longitude is positive, we subtract 180° to ensure the final value lies between (-180, 180). If it were the other way around, we would sum 180° for the same reason.
Result:
The antipode of Rosetta is located on coordinates: (LatA, LngA) = (-31.39951, -149.58282)
In DMS format: 31°23'58.2'' N 30°25'1.8'' E .
