Figure 8 and 8a below. The daily path of the Sun as seen from Hawai'i on the first day of spring, summer, fall, and winter. This is what gives us our seasons here on Earth.

When the North Pole is tilted toward the Sun, the Northern Hemisphere experiences summer, and the Sun is high in the sky at noon. During the winter, the North Pole is tilted away from the Sun, and at noon the Sun doesn't get nearly as high in the sky. Earth's tilt also explains why the longest day of the year occurs on the summer solstice usually around June Likewise, the shortest day of the year occurs on the winter solstice usually around December The combination of Earth's elliptical orbit and the tilt of its axis results in the Sun taking different paths across the sky at slightly different speeds each day.

This gives us different sunrise and sunset times each day. Once the summer solstice passes, you'll notice the days begin to get shorter each day. This trend continues until the winter solstice, the shortest day of the year. After the winter solstice, days get slightly longer each day up until the summer solstice, and the process repeats year after year. Are you ready to rise and set with the Sun?

That's right, henriqDA24! The sun rises at different times throughout the year because Earth is tilted on its axis!

This means that the Sun does not rise earlier by a fixed number of minutes every morning and set later by the same number of minutes. A quick glance at an astronomical almanac or a calendar showing sunrise and sunset times reveals that these do not change evenly.

While the Sun rises only a little earlier every day at the beginning of the year, it sets noticeably later every evening. For example, on February 1, in Berlin, the Sun rose 25 minutes earlier than on January 1, but it set 45 minutes later. In spite of this 'asymmetrical' change, the 'solar noon' — the moment when the Sun appears highest above the horizon — always falls midway between sunrise and sunset.

The amount of time between sunrise and solar noon remains more or less the same as the amount of time between solar noon and sunset. Thus, the days get longer but the Sun actually only rises a little bit earlier every day and still reaches its highest point in the sky at midday.
