First Ring System Around Asteroid (2014)

https://en.wikipedia.org/wiki/Hydrostatic_equilibrium#Planet... claims the limit of hydrostatic equilibrium for rocky bodies is ~400-500km, so probably not.

With a diameter of 160 Km, it'd be the smallest one, by far. This is particularly interesting because I don't think there's anything round with this size in the system - and a circular ring indicates that.

Do we have instruments able to directly image it?

The dimensions listed are 296 × 264 × 204 km. It’s kind-of round-ish, but not spherical.

Finally, a practical use for AR goggles!

We could just kill all the light pollution and give everyone something truly spectacular to look at.

Earth has several rings now; a ring of satellites at geostationary orbit, and an accretion disk of space trash at the equator in LEO.

Also for fun try the "Sky Guide" app and have it alert you when the ISS is visible overhead. That is fun to look at. And the planets have been really nice this month, with Venus, Jupiter, Saturn, and Mars all super bright. So nice!

LEO billboards?

Ring systems are most enjoyable to look at when you're not in the plane of the rings. From in the plane, you're looking at them side-on, and they're flat, so that's a thin line across the sky. On earth, you would always be (roughly) in the plane.

Really, you want to add rings to the moon.
