Ahh, comparative planetology- the principle that one world is not one unique snowflake, but that it tells you things about other worlds by analogy. Scully et al. pick a fairly direct analogy: the ice content and activity of Ceres should reflect on the natural satellites Umbriel and Oberon, which haven’t gotten space missions.
Somewhat similar but far smaller, Vinogradoff et al. study organics (like on Ceres!) by way of what we have- Earth examples.
You may have seen Nugent, et al. in some lay press. The odds of harm by asteroid impact are nonzero, but what? At minimum, the amount of harm (scaled by the odds) makes asteroid telescopes worthwhile- they pay for themselves.
We have samples of Ryugu and Bennu, plus the orbiter images and other results. But what broader context do they form? Both asteroids are rubble piles, after a defining collision event. Is asteroid Polana the context, as the parent asteroid?
We can only speak of Polana through remote sensing- telescopic studies. That’s a quite limiting state of affairs. We also see the M-type and K-type asteroids- what are their natures? Fortunately, Masiero et al. studied the two types with polarimetry, one of the better telescopic methods that we have.
The DART program did far more than image Dimorphos. As a direct, dramatic experiment, we are now witnessing several effects on that asteroid. Knowing the properties of the DART spacecraft, and some initial numbers of Dimorphos, Lolachi et al. try to work out the impact process in between.
Binary asteroids (like Didymos-Dimorphos) can tell us a lot. Storrs et al. broaden our portfolio of asteroid systems, using the Hubble Telescope to find binaries.
Apophis is not a binary, but… it’s no sphere, clearly. And when the asteroid makes its close Earth flyby in 2029, our gravity will clearly treat the body like an extended mass. As a first cut, Wang et al. consider Apophis as two masses, to be pulled.
