Why We Have Seasons

Ғылым және технология

How did Earth get its season? Neil deGrasse Tyson and comedian Chuck Nice explain how the Earth got its seasons, its axial tilt, the Milankovitch Cycle, and more! What are seasons like on other planets?
Neil breaks down the biggest misconception about Earth’s elliptical orbit. Why is noon not the hottest time of day? Why is June not the hottest month of the year? We explore the Hadean Period and how the Earth got its tilt, the Milankovitch Cycle, and what causes ice ages. Plus, discover what seasons on Venus and Uranus are like.

The effect the lake's surface temperature has on surface temperatures on land (if you're close enough to the lake) is quite substantial in the spring and very early summer. And the opposite occurs in the fall and early winter. 🙂

    When one talks about the planetary tilts, how is horizontal and vertical determined in space? What is the reference point or what are they measuring it against to determine horizontal and vertical? Not sure if I am asking this question correctly but perhaps someone will understand what I am getting at lol.

  • @mriandecker6533

    @mriandecker6533

    So, when we describe the tilt of a planet, it's with respect to that planets orbit around the sun. So, take the Earth. Assuming that its orbit is 0 degrees, Earth tilts 23.5 degrees off its orbital plane. For describing a tilted orbit, it's with respect to the sun itself. Assuming that the sun's tilt is at 0 degrees, any planets orbit is measured from that. That being said, there is no universal reference point. Everything has to be measured with respect to something else, in this case, the sun is that reference point. Hope this helps you to understand!

    @@mriandecker6533 A tilted orbit such as Pluto's is usually specified in relation to either the Earth's ecliptic (orbital plane) or the invariable plane which is the average orbital plane of the entire solar system. The Sun's equator does not match either of those. Neil said Pluto's orbit is tilted 17 degrees, that is relative to the ecliptic. Look up 'invariable plane' in wikipedia if you want more information including the sun's tilt in relation to both the ecliptic and invariable plane.
