Earth's Tilt and the Seasons - for Planetarium Show

This short animation was created to help clarify how the tilt of Earth's axis causes the change of the seasons. It was made specifically for use in the wonderful Planetarium Show "In My Backyard." The animation syncs up with a specific part of the audio from that show. That bit of audio is used here, no copyright infringement is intended!

For more animations on this topic, including one that uses those old red and blue 3D glasses, please see my other videos. (or search for "Earth Orbit - Anaglyph")

For more information, requests for animation useage or anyone who likes it please visit my website to contact me. www.bradfreese.com Note: Classroom teachers / any other noncommerical work please use this animation with my blessings!

I love how short and simple this was - thank you!

This video is deceiving because it makes it seem as if the Earth changes its tilt by itself as opposed to having a fixed tilt, but different position around the sun.

It's very unfortunate that, from the point the Earth appears to go into retrograde motion (by virtue of the 'camera' suddenly changing from fixed to co-moving), the direction of the Earth's axis appears to change. I think the single most important point to get across is that our rotation axis essentially does not change its direction in space as we move around the sun. Anything that does not elucidate this is plain confusing (even though it might appear elegant to those already 'in the know').

@ActiveStorage Sure there's a wobble. But it takes 26,000 years to complete one full cycle of the wobble, and this video makes it look like it takes just one year.

[ActiveStorage]

@BoundaryShift are you saying there is no wobble in the earth's rotational axis?

[MrHUMICK]

This Video only shows you about 1/4 of the earth's actual rotation around the sun... Its not that simple... The earth does not travel in a circular motion around the Sun, in fact it travels in different loop shapes every year.

@wetweasel56 ha ha haaa...that's what everybody wants to know. Wonder why i hadn't ponder that small error of explanation before

[newagecozaki]

Yes this video is very deceptive....if the earth maintains a constant tilt as it revolves around the sun, then that does not explain how sometimes the northern hemisphere is tilted forwards whilst the southern is tilted backwards wrt the sun and vice versa at other times. I dont get it!

To make this accurate, wouldn't the earth spin on its axis 365 times?

ummm is it just me or does a year happen in about one week in this vid??
