Since you're along for the ride anyway, here are a few tidbits
about your vehicle on these first days of summer. Earth's axis is currently tilted at an angle of 23.44° relative
to its orbital plane, and represents the maximum northward or southward track where the sun can be directly
overhead (zenith) at noon. The Tropic of Cancer and Tropic of Capricorn are located at 23.44° of latitude
accordingly. The northern summer solstice (from Latin terms meaning "the sun standing still") occurs when the sun
reaches the Tropic of Cancer, and the winter solstice occurs at the Tropic of Capricorn. Due to minor
gravitational tugs by neighboring planets, the tilt angle varies between 22.0° and 24.5°, and is currently
decreasing by 0.47 second of arc per year. The entire precession period occurs in about 25,700 years.
