What’s important though is that it’s large enough to hold an atmosphere (at least if it had one).
Define an atmosphere. Because there’s multiple asteroids that technically have one, albeit extremely thin ones. And be careful about being too nitpicky, as Mercury’s atmosphere is just it’s rock being vaporized due to its proximity to the sun

oh wait maybe you’re talking about something like this:
yeah, no, i don’t consider that an atmosphere. it’s individual molecules bouncing around, but they don’t fulfill the “statistical” character of gases.
