- Straight-Line Displacement measures how far you are from your birth coordinate in a straight line, ignoring Earth's rotations and orbits.
- Rotated: Distance moved due to Earth's spin. At the equator: ~1,600 km/h (1,000 mph). At poles: 0.
- Orbited Sun: Earth moves around the Sun at ~107,000 km/h (66,000 mph), representing your yearly lap.
- Solar Travel: The Sun drags planets around the Milky Way at ~792,000 km/h (490,000 mph).
- Galactic Travel: Our Galaxy moves at 2.1 million km/h (1.3 million mph) relative to the Cosmic Background.
- Total Distance: The sum of all these speeds combined into one total path length since birth.
