The nearby (78 pc) K-star K2-266 hosts six possible planets in a compact system — including one with an inclination that is significantly misaligned with the other five planet candidates, suggesting a different origin.

Over 4.5 years, the Mission Accessible Near-Earth Object Survey assembled 228 near-Earth object (NEO) light curves; the team characterizes two NEOs as appropriate targets for a potential robotic/human mission.
Adam M. Dempsey and Benjamin E. Nelson 2018 ApJ 867 75
Dissipative N-body simulations demonstrate that the GJ876 system, an M-dwarf hosting three planets orbiting in a chaotic 4:2:1 Laplace resonance, can be formed through smooth disk migration models.
