Red metallic rectangular shaped object spinning horizontally in sky.

I noticed something strange in the sky, so I grabbed my binoculars for a closer look. Binoculars are Galileo Model G-1250 so I can see 12 times farther than the naked eye. In the field of view through the lenses, the object was about 1/2 inch wide and 1/3rd of that in height. Rectangular shaped and red. It was the color of a cherry. The object spun horizontally, which doesn't make any sense. It really looked like a car, and that doesn't make any sense. It even looked like there was a wheel too, a small one - with a rim, the same as a car wheel would. I could not make sense of this thing. I even wondered of it was that Tesla that Elon Musk released into space, but it wasn't falling fast like it should have with the gravitational pull. The object was too strange to be a plane or an air balloon. It wasn't a helium balloon. It was too big to be a drone. I do not think a remote controlled device can fly that high, but I do not know. It was just a spec in my eye w! ithout the binoculars. I grabbed the binoculars because of the flash the sun made on it when it spun. The spin speed was about as fast as a beacon light for aircraft to see. The metallic sheen flashed brightly when the sun reflected upon it, when the object made a horizontal rotation. I put down the binoculars to try and focus my eyes on it and try to get a photo, but when I looked up again it was gone. I only took my eyes off of the object for a 2/10ths of a second. I regretted putting my binoculars down. I was facing south, and the object would be about south west if the face of the compass were facing me. There were no lights. I can hear sound through my windows, but only a small amount. I heard no sound coming from the object, and there were no streaks. The sky at the time, as I looked through my window, was cloudy, but blue sky was also visible, and the sun was able to flash off of the object. This sighting happened around 4:52pm on June the 18th.
