Now that's the Tropic of Cancer in the north and the Tropic of Capricorn in the south, that much I knew, but I was surprised to learn this little fact: Those are not cartographers' lines, like latitude or the borders between nations, they are astronomical phenomena caused by the Earth's tilt, and they change.
Ovo je Rakova obratnica na sjeveru i Jarčeva obratnica na jugu, toliko sam znao, ali iznenadio sam se ovom činjenicom: To nisu kartografske linije, poput paralela ili granica između zemalja, to je astronomski fenomen koji nastaje zbog promjene kuta Zemljine osi i obratnice se mijenjaju.
