π Understanding Solstices
The solstices mark the times when the Sun reaches its highest or lowest point in the sky at noon, resulting in the longest and shortest days of the year. These events are caused by the Earth's axial tilt of approximately 23.5 degrees relative to its orbit around the Sun.
βοΈ Summer Solstice Defined
The summer solstice occurs when a hemisphere is most inclined towards the Sun. It marks the longest day of the year and the beginning of astronomical summer in that hemisphere.
βοΈ Winter Solstice Defined
The winter solstice occurs when a hemisphere is most inclined away from the Sun. It marks the shortest day of the year and the beginning of astronomical winter in that hemisphere.

π Key Takeaways
- βοΈ The summer solstice brings the longest day and the start of summer to the hemisphere tilted towards the sun.
- βοΈ The winter solstice brings the shortest day and the start of winter to the hemisphere tilted away from the sun.
- π These solstices are opposite in the Northern and Southern Hemispheres. When the Northern Hemisphere experiences summer solstice, the Southern Hemisphere experiences winter solstice, and vice versa.
