Interstellar interlopers are bodies formed outside of the Solar System but observed passing
through it. The first two identified interlopers, 1I/'Oumuamua and 2I/Borisov, exhibited …

Over the course of the past two decades, observational surveys have unveiled the intricate
orbital structure of the Kuiper Belt, a field of icy bodies orbiting the Sun beyond Neptune. In …

Our understanding of planet formation has been rapidly evolving in recent years. The
classical planet formation theory, developed when the only known planetary system was our …

Little is known about the origin of the spectral diversity of asteroids and what it says about
conditions in the protoplanetary disk. Here, we show that samples returned from Cb-type …

Astronomical observations reveal that protoplanetary disks around young stars commonly
have ring-and gap-like structures in their dust distributions. These features are associated …

The nature and origin of free-floating planets (FFPs) are still largely unconstrained because
of a lack of large homogeneous samples to enable a statistical analysis of their properties …

Context. Methods used to detect giant exoplanets can be broadly divided into two
categories: indirect and direct. Indirect methods are more sensitive to planets with a small …

Abstract The Solar System's orbital structure is thought to have been sculpted by an episode
of dynamical instability among the giant planets,,–. However, the instability trigger and timing …

The current state and surface conditions of the Earth and its twin planet Venus are drastically
different. Whether these differences are directly inherited from the earliest stages of …

Updated formation and structure models of Jupiter predict a metal-poor envelope. This is at
odds with the two to three times solar metallicity measured by the Galileo probe …
