We studied a sample of 93 asteroid pairs, ie, pairs of genetically related asteroids that are on
highly similar heliocentric orbits. We estimated times elapsed since separation of pair …

Context. The recent close approach of the near-Earth asteroid (3200) Phaethon offered a
rare opportunity to obtain high-quality observational data of various types. Aims. We used …

Context. Asteroids smaller than about 100 m in diameter are observed to rotate very fast,
with periods often much shorter than the critical spin limit of 2.2 h. Some of these super-fast …

We obtained thorough photometric observations of two binary near-Earth asteroids (66391)
Moshup= 1999 KW4 and (88710) 2001 SL9 taken from 2000 to 2019. We modeled the data …

Context. The rotation states of small asteroids are affected by a net torque arising from an
anisotropic sunlight reflection and thermal radiation from the asteroids' surfaces. On long …

Context. Small binary asteroid systems and pairs are thought to form through fission induced
by spin up via the Yarkovsky-O'Keefe-Radzievskii-Paddack (YORP) effect. This process is …

Context. The close approach of the near-Earth asteroid (99942) Apophis to Earth in 2029
will provide a unique opportunity to examine how the physical properties of the asteroid …

Context. Asteroids with a diameter of up to a few dozen meters may spin very fast and
complete an entire rotation within a few minutes. These small and fast-rotating bodies are …

Context. The measurement of the Yarkovsky effect on near-Earth asteroids (NEAs) is
common practice in orbit determination today, and the number of detections will increase …

Asteroid 2012 TC4 is a small (∼ 10 m) near-Earth object that was observed during its Earth
close approaches in 2012 and 2017. Earlier analyses of light curves revealed its excited …
