#189…SCIENCE, religion, etc.: “Planet Facts You Don’t Know

Here’s some new information

you don’t know about




(the 8 “hometown” ones of our solar system

I’m referring to…)


To bait the hook:


“One day on Mercury is 2 years long.”


For more use the DOOR. 




     The information here is adapted from Johnna Rizzo’s “Seasonal Flux” that appeared in the Jan. 2014 issue of National Geographic. Let me put some data in chart form. (Known or implied: “1 year”= 1 earth year, or Earth revolution around the Sun; planets cited rotate and roughly tilt on an axis similar to Earth; and Jupiter, Venus, and Mercury have little or no “tilt” and hence no “seasons.”)


PLANET            LENGTH OF SEASON        

Earth                                   90 days

Mars                                    7 months

Saturn                                  8 years

Uranus                               21 years

Neptune                            41 years

     Curious appearing, perhaps, is that all bodies in space are moving away from each other, twisting, spinning, and revolving in curved paths around other larger objects, which in “turn” revolve in “neighborhoods” around much larger objects that can’t be seen that are so large that gravity keeps light from them escaping.

     Each “solar system”–think of ours as an example–and each galaxy (ours is the Milky Way) and each larger “neighborhood” has its irregularities and variations. I’ve just shown you some of ours.

     And it just so happens that Earth has turned out just right for life, and especially for humans.

     That’s the way we think nowadays as we look at the sky…

     Oh…and as to Mercury, it takes 2 of its years between dawn and sunset to occur on just one of its days. Think of the extreme changes that must take place on the planet’s surface…
