  • The peculiar object P/2010 A2, discovered in January 2010, is in an asteroidal orbit in the inner main asteroid belt and was given a cometary designation because of the presence of a trail of material. These authors report observations of P/2010 A2 by the Rosetta spacecraft. They conclude that the trail arose from a single event, an asteroid collision that occurred around 10 February 2009.

  • The brightness variations of the interstellar object 1I/’Oumuamua observed during six nights are incompatible with a unique rotation rate, indicating that the body is tumbling. Colour measurements suggest a heterogeneous surface, with a large red region.

  • Visible and near-infrared spectra of the interstellar object ‘Oumuamua indicate the presence of inhomogeneities in surface composition, which are dominated by organic-rich material after long-term exposure to cosmic rays. An ice-rich interior is not ruled out.

  • The 33 minute change in the orbital period of Dimorphos after the DART kinetic impact suggests that ejecta contributed a substantial amount of momentum to the asteroid compared with the DART spacecraft alone.

  • Observations with the Hubble Space Telescope reveal a complex evolution of the ejecta produced by the Double Asteroid Redirection Test (DART) spacecraft impacting Dimorphos.

  • The European Space Agency (ESA) recently selected Comet Interceptor as its first ‘fast’ (F-class) mission. It will be developed rapidly to share a launch with another mission and is unique, as it will wait in space for a yet-to-be-discovered comet.

  • ‘Oumuamua is the first interstellar interloper observed in our Solar System and studied in some detail. This Perspective reviews the data acquired during its visit and discusses its origin and properties, concluding that there is no basis to the theory of an artificial ‘Oumuamua.
