Spikey Orb hovering. I thought it was a balloon. Came back and it was gone.

Driving home at 8:28pm and here, above a field near home, about house height from the ground was a black, spiky looking orb. Looked like a sun shaped birthday balloon but it was black. No lights, no sound just hovering. I thought someone tethered a helium balloon in the field just behind their house. There was a bicyclist going the same way as us. We noticed him turn around, it must have been unusual for him too. We found an opportunity to turn around. We we got back to the main street and we saw the biciclist standing and looking back where it was. There was no object. I rolled down the window and said "Was that a balloon?" he said "I don't know, it just disappeared. All of this happened in the span of 2 minutes.
