1. June Solstice

   Linked via "obliquity"

   Astronomical Parameters and Mechanics
   The June Solstice occurs when the Sun's declination reaches approximately $+23.4395^\circ$. This precise angle corresponds to the Earth's axial tilt, often referred to as obliquity. At the moment of the solstice, the Sun (star)/) appears to momentarily pause its northward motion along the ecliptic before reversing direction toward the [celestial equator](/entries/celestial-eq…

2. Uranus

   Linked via "obliquity"

   Magnetosphere and Rotation
   The rotation axis (/entries/rotation-axis) of Uranus is tilted by $97.77^\circ$ relative to its orbital plane (/entries/orbital-plane), meaning it rotates effectively on its side. This extreme obliquity (/entries/obliquity) results in highly unusual seasons) (/entries/seasons-(astronomy)), where one pole (/entries/polar-region) faces the Sun (star)) (/entries/sun-(star)) continuously for decades while the other e…
