When I first read this I assumed that there was an error in the captions: at a little under 10,000 km range Bennu is only 3.7 pixels in Polycam? But it's true, and that just goes to show how dinky Bennu is. Polycam's IFOV is 13.5 urad so at range R Bennu (246 meters mean radius) subtends 0.246*2/(R*13.5e-6) pixels. -------------------- Disclaimer: This post is based on public information only.
