Several properties of the Solar System, including the wide radial spacing of the giant
planets, can be explained if planets radially migrated by exchanging orbital energy and …

We provide a nonspecialist overview of the current state of understanding of the structure
and origin of our Solar System's transneptunian region (often called the Kuiper Belt) …

Abstract The observable Solar System can be divided into three distinct regions: the rocky
terrestrial planets including the asteroids at 0.39 to 4.2 astronomical units (au) from the Sun …

Abstract The Wide Field Survey Telescope (WFST) is a dedicated photometric surveying
facility being built jointly by University of Science and Technology of China (USTC) and the …

Abstract The Vera C. Rubin Observatory is expected to start the Legacy Survey of Space and
Time (LSST) in early to mid-2025. This multiband wide-field synoptic survey will transform …

Here we measure the absolute magnitude distributions (H-distribution) of the dynamically
excited and quiescent (hot and cold) Kuiper Belt objects (KBOs), and test if they share the …

We utilize ALMA archival data to estimate the dust disk size of 152 protoplanetary disks in
Lupus (1–3 Myr), Chamaeleon I (2–3 Myr), and Upper-Sco (5–11 Myr). We combine our …

Abstract The Outer Solar System Origins Survey (OSSOS), a wide-field imaging program in
2013–2017 with the Canada–France–Hawaii Telescope, surveyed 155 deg 2 of sky to …

Comets have three known reservoirs: the roughly spherical Oort Cloud (for long-period
comets), the flattened Kuiper Belt (for ecliptic comets), and, surprisingly, the asteroid belt (for …

We present a search for outer solar system objects in the 6 yr of data from the Dark Energy
Survey (DES). The DES covered a contiguous 5000 deg 2 of the southern sky with≈ 80,000 …
