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

on that site i found this:
but no other mention of air or atmosphere on that object.
