Didn't even notice the dumbness was still going on. The word "pixel" is a contraction of the term PIC-ture ELement. The practice of taking the word "pictures" and turning it into "pix" is lost in time but was around in the 1800's. The adoption of the word pixel for computer use started in the 60's.
A pixel by itself has no dimension. It is a point. What you people are confusing is the size of the dot. You can take a magnifying glass and hold it up to your monitor, then you will see a dot size. That doesn't mean that defines the size of the pixel. Astronomy sloppily interchanges the word pixel to mean "sensor size". Yes, the sensor has dimensions and it will be comprised of an array of transistors. This is a 4K CCD.

Good grief. This is the same junk that was going on when HD was first being introduced. No wonder the Japanese were first. The use of the word "pixel" is like use of the term "K". K is sloppily used as 1000 when it is 1024. Computer geeks know this and just adjust mentally to its use in context. The question was mangled, like when a child asks "How many stars are there in the sky?". The question is malformed, not the subject. BTW, the example pix of what a pixel looks like is obsolete. Ask someone in Japan why.
