Slowly moving low and large star shape craft was observed and watched till it passed overhead.followed by another

I watch stars nightly and identify them with a App that follows them and satellites.
I have done this dutifully nightly for last 7-10 years as I walk my dog between 9-12 pm. I also awaken between 4-5 ea. morning to let him out for a nature break in our back yard.
I have good knowledge of where all major stars are, their travel patterns, times ETC. after years of studying them.
The early morning this happened I didn’t have my cell phone.
I walked out on our patio and scanned the skies paying Attention to Jupiter and Saturn which was where the moving bright light was positioned slowly moving towards me fairly low and getting larger as it approached.
I have wanted to spot a UFO for the last ten years, read about sightings but had never witnessed one.
I studied it as it approached and could not see any FAA lights, just a solid bright light with a blueish hue. As it got very close It was obviously not anything conventional as it resembled a flat star and there were no moving aircraft anywhere in sight. It travelled at a pace a little faster than a jog.
Frozen it was almost overhead and it’s detail became evident. Traveling at 500-1000 feet it was as dimensionally as big as a 747
At least 100-150 feet from corner to corner. It was two triangles forming a singular flat star shape.
Third thing that was so eerie was the total silence. It doesn’t compute. How can anything this large right above you be so quiet?
By now my heart was racing and I ducked under our back porch kinda scared.
I ran inside to have my wife join me but she’d just commenced a shower.
I yelled for her to come out and ran back outside. It was passing towards the NE. In the direction of NE AZ. When it had passed out of sight I ran back inside babbling about it to my wife dragging her outside in her towel. I was describing what had just happened and was pointing to where it had first been observed.
When another exact craft but much higher like at least 10,000 ft. appeared to follow the exact same path. My wife watched it slowly pass and we went back inside.
My BP was pretty high and I felt like I had several cups of coffee.
I immediately wrote about what I saw to a report form in MUFON.
I am sure there had to be others that witnessed it. I checked the airplane traffic app I keep on my cell and the only planes at that time in the sky were two FedEx planes leaving Tucson way south of PHX.
I can’t help but think it was observed by Airport personnel that morning as it passed just to the west of PHX airport.
Most commercial flights start leaving around 5am so I’m sure someone else saw this thing.
The craft seemed to be projecting a light out in front of it. As it moved it was not linear. Kind of like taking steps. The middle was same color as sky which was still dark then. The outlines were what was bright and ea. 4 corners came to a point all the sides lit very brightly.
Seeing the second one w my wife made me feel better cause you immediately worry no one will take you credibly.
The lack of noise is what really stands out about my experience.
