The June 2025 issue of Icarus (vol. 433) is a good one:

Planet Nine: no way to not have an opinion of it (assuming you’re up to speed on the question). It even touches upon seemingly separate bodies: what does the presence (/absence) of a new planet imply for the rest of the Solar System? Ask Ribeiro de Sousa et al., at least re: comets passing (?) Planet Nine.
Pit crates: also a bit of a sticking spot. Pit craters are craters that, in their basins, appear to have a second crater there. While there’s certainly a chance that the second crater is a cosmic “bullseye/hole in one”, odds are that the (first) crater impacted in volatile-rich territory. The second crater, then, is not an impact feature at all, but cryo-related, possibly cryovolcanic. The disturbance melted subsurface ices, which then escape, leaving a pit. de Luis et al. walk us through pit craters on ice-bearing asteroids.
Venus trojan asteroids: unlikely (due to Earth’s strong disturbances) yet not impossible, at least on short (for the Solar System) timescales. And when a small body enters or leaves the trojan state, it typically does so through one of several commensurate orbits: horseshoe, quasi-satellite, etc. It may even enter and leave trojan-hood or other states repeatedly.
Speaking of temporary, what of impacting meteors? 2024 XA1 was such an asteroid, discovered on an inbound trajectory. Are there any samples to be had, without any sample return spacecraft?
Similar to pit craters, polygonal craters tell us of the subsurface that an impactor impacts. In the case of these craters, a nonround shape implies the ground was riven with fractures before the impactor hit. Vesta and Ceres were well-photographed by the Dawn mission; what do their nonround craters tell us?
Meteors fall all the time, becoming meteorites (…nominally). Some meteors are completely disrupted, leaving little but ash and vapor. In between, we have meteors that split, forming paired meteorites. Since we see numerous examples of bilobate comets (and some bilobate asteroids, such as Donaldjohanson), what does that imply for finding multiple meteorites after a meteor entry? Li et al. are on it.
That Dawn mission had the good fortune of orbiting large, hydrostatically-equilibrated worlds. That is, Vesta and Ceres had enough gravity to overcome the strength of rock, and thus pulled themselves into more or less sphere shapes. Sphere shapes result in sphere gravity fields and sphere orbital paths. But this is not the general case: most asteroids are potato-shaped, with irregular gravities. How does one orbit in an irregular force field? Duan et al. attempt a new method: better computer algorithms.
