Summary[edit]
| Description |
English: The durations of the seasons. The season lengths are different because Orbital mechanics require that the length of the seasons be proportional to the areas of the seasonal quadrants, so when the eccentricity is extreme, the seasons on the far side of the orbit can be substantially longer in duration. Today, when fall and winter occur at closest approach, the earth is moving at its maximum velocity and therefore fall and winter are slightly shorter than spring and summer. Today, summer is 4.66 days longer than winter and spring is 2.9 days longer than fall. |

The depicted text is ineligible for copyright and therefore in the public domain because it is not a “literary work” or other protected type in sense of the local copyright law. Facts, data, and unoriginal information which is common property without sufficiently creative authorship in a general typeface or basic handwriting, and simple geometric shapes are not protected by copyright.
This tag does not generally apply to all images of texts. Particular countries can have different legal definition of the “literary work” as the subject of copyright and different courts' interpretation practices. Some countries protect almost every written work, while other countries protect distinctively artistic or scientific texts and databases only. Extent of creativeness, function and length of the text can be relevant. The copyright protection can be limited to the literary form – the included information itself can be excluded from protection.
