So, I got curious and looked it up.
"The "canonical" (that is, commonly accepted) day length on Jupiter is determined by the rotation rate of its magnetic field, which is nine hours, 55 minutes long."
They say you learn something everyday. Well, I may have been told this before but today, I learned (or was reminded again) that Jupiter is the fastest rotating planet in our solar system and that it's measured by its magnetic field (that part, I did not know).
More useless, trivial p o o p that I will carry around with me....like I need more.

A 9-hour day...
Some people would love the 3 hr. work period 3 days a week.
Most people just listen to music and watch movies. I EXPERIENCE them. -
THE moon launch is a GO for Monday...already thousands in the area as there is a night SpaceX launch this weekend, and night launches always draw a crowd..amazed at the number of visitors from out of Country.

Yep, Jupiter is one of the 'Gas Giants', with a relatively small rock core...but nonetheless still larger than Earth. Most of Jupiter is metallic liquid hydrogen. I'm not sure I can even process what that is like. I guess it's something similar to liquid Mercury.

I'm just the opposite of Jupiter.
I have a rock exterior and a gaseous core. -
What is mind boggling is the size of the giant red spot/hurricane.
Could swallow the earth.

Bonus launch for those in town...10:20pm will see the launch of yet another SpaceX rocket full of satellites to pollute the space around us..it is a night time launch and they are very cool to watch..

Back to Jupiter for a second. I woke up this morning and got to wondering about this planet again. We already know that Jupiter's day is only a little over nine hours long. Looking at the photo below, I got curious as to the surface speed (if there was a surface) of Jupiter.
Earth rotates once in 24 hours; Jupiter once in about 9.3 hours. The surface of Earth at the equator is rotating at about 1000 miles per hour, while Jupiter's equatorial cloud-tops are moving nearly 28,000 miles per hour.

Another facinating factoid....Earth is spinning around our galaxy at a whopping speed of 490,000 miles per hour, as the Earth spins on axis at 1Kmph while spinning around our sun at 67,000mph.
Meanwhile, the current wind speed is only 10-15mph where I am right now.

Lots of energy involved in that spinnin' and whizzin' around.Another facinating factoid....Earth is spinning around our galaxy at a whopping speed of 490,000 miles per hour, as the Earth spins on axis at 1Kmph while spinning around our sun at 67,000mph...
To put this in a bit of perspective. Think of balls bouncin' and spinnin' around on a pool table after a break. That's pretty much what we're lookin' at, with the break, presumably, having been the Big Bang.
Quite a break.

Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto. Subject to memorization in school and known as the definitive planetary lineup, Pluto was included in the list until the International Astronomical Union determined it did not meet qualifications in 2006.
Though Pluto is no longer considered a major planet, it's still beloved by the science community and regularly makes headlines. The National Aeronautics and Space Administration recently posted a technicolor photo of Pluto, created by scientists to show subtle differences between its regions.
Here's why Pluto isn't officially considered a planet anymore.
Why is Pluto not a planet?
Pluto came into the lexicon in 1930 when astronomer Clyde Tombaugh discovered it when searching for signs of a planet. It wasn't until the early 2000s that researchers began developing the qualifications for a celestial body to be considered a planet.
In 2006, the IAU voted that the definition of a planet relied on three specifications:
It orbits around the sun
It has sufficient mass so that it becomes a nearly round shape
It has cleared the neighborhood around its orbit
IAU members also concurred that dwarf planets and planets are two distinct classifications. They determined the solar system contains eight planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.
Pluto does not meet the third criteria because it is not gravitationally dominant, the Library of Congress reports. This means Pluto is classified as a dwarf planet rather than a major planet like its formerly assumed siblings.
What are dwarf planets?
Dwarf planets are smaller planets that do not meet all three categories of a planet. According to NASA, they are round in shape and orbit the sun, but don't clear their orbital path. There are currently five recognized dwarf planets in our solar system, listed here in order of closest proximity to the Earth:
Ceres: Located in the Asteroid Belt between Mars and Jupiter, discovered in 1801
Pluto: Located in the Kuiper Belt, discovered in 1930
Eris: Located in the Kuiper Belt, discovered in 2003
Makemake: Located in the Kuiper Belt, discovered in 2005
Haumea: Located in the Kuiper Belt, discovered in 2003
Controversial categories
While the IAU definition of planets remains the globally adopted one, that doesn't mean it's unanimously accepted. Some planetary experts dispute the 2006 vote, saying the definitions are arbitrary. In 2018, scientist Philip Metzger from the University of Central Florida published a study that suggested the standard for classifying planets is not scientifically sound.
Metzger argues that planetary scientists use the word "planet" in a number of ways because it's a functionally useful term, and that a planet should be defined by its intrinsic properties rather than its orbit, which can change over time.
"It's more dynamic and alive than Mars," Metzger said in a UCF press release, referring to its underground ocean, multiple moons, organic compounds and multilayer atmosphere. "The only planet that has more complex geology is the Earth."
NASA's Alan Stern also disagrees with the IAU. In an interview with Forbes, he said all dwarf planets should be considered planets for a number of reasonsโone being that the solar system contains so many asteroids that no celestial body has cleared the neighborhood of its orbit.

But...
It identifies as a planet.
Case closed. It's 2022. -
People already staking out places to see the launch try #2 and we are over 2 days away...expecting a larger crowd than the first attempt due to the fact it's Labor Day weekend.....A real shot in the arm financially for a town of 48,000....took almost 4 hours to clear the cars out of town....we have a great view from the house..

I will just drop this right here... I remember these launching way back in the day. It amazes me they are still out there doing their jobs pretty much as designed, but we can't get a toaster to work for six months before it's junk.

Is Neptune in danger of its current classification as well?
"Technically" Plutoโs orbit does cross Neptuneโs orbital path along with other objects in our solar system which the IAU classified Pluto as dwarf planet due to not clearing other object from its orbit . But one could argue that Neptune also hasnโt cleared its orbit around Pluto and Kuiper Belt Objects too since its orbit is crossed with theirs which means Neptune is technically a dwarf planet.
According to the IAU, clearing the neighborhood from other objects means a body thatโs gravitational dominant to the point that it has strong influence over other objects in its orbital path.
