YORP Effect on Asteroid 162173 Ryugu: Implications for the Dynamical History

Masanori Kanamaru Sho Sasaki Tomokatsu Morota Yuichiro Cho Eri Tatsumi Masatoshi Hirabayashi Naru Hirata Hiroki Senshu Yuri Shimaki Naoya Sakatani Satoshi Tanaka Tatsuaki Okada Tomohiro Usui Seiji Sugita Sei-ichiro Watanabe

JOURNAL OF GEOPHYSICAL RESEARCH-PLANETS 126(12) 2021年12月

Asteroid 162173 Ryugu is a carbonaceous asteroid that was visited by Japan's Hayabusa2 spacecraft in 2018. The formation mechanism of the "spinning-top" shape of Ryugu is a vital clue to the dynamical history of the near-Earth asteroid. In this st...
