The spatial distribution of impact craters on Ryugu
Naoyuki Hirata, Tomokatsu Morota, Yuichiro Cho +40
Asteroid 162173 Ryugu has numerous craters. The initial measurement of impact craters on Ryugu, by Sugita et al. (2019), is based on Hayabusa2 ONC images obtained during the first…
High-Resolution Observations of Bright Boulders on Asteroid Ryugu: 1. Size Frequency Distribution and Morphology
Chiho Sugimoto, Eri Tatsumi, Yuichiro Cho +34
The near-Earth asteroid (162173) Ryugu displays a Cb-type average spectrum and a very low average normal albedo of 0.04. Although the majority of boulders on Ryugu have reflectance…
High-Resolution Observations of Bright Boulders on Asteroid Ryugu: 2. Spectral Properties
Chiho Sugimoto, Eri Tatsumi, Yuichiro Cho +34
Many small boulders with reflectance values higher than 1.5 times the average reflectance have been found on the near-Earth asteroid 162173 Ryugu. Based on their visible wavelength…
Hayabusa2 Extended Mission: New Voyage to Rendezvous with a Small Asteroid Rotating with a Short Period
M. Hirabayashi, Y. Mimasu, N. Sakatani +41
Hayabusa2 is the Japanese Asteroid Return Mission and targeted the carbonaceous asteroid Ryugu, conducted by the Japan Aerospace Exploration Agency (JAXA). The goal of this mission…
The Western Bulge of 162173 Ryugu Formed as a Result of a Rotationally Driven Deformation Process
Masatoshi Hirabayashi, Eri Tatsumi, Hideaki Miyamoto +26
162173 Ryugu, the target of Hayabusa2, has a round shape with an equatorial ridge, which is known as a spinning top-shape. A strong centrifugal force is a likely contributor to Ryu…
Thermal conductivity and coordination number of compressed dust aggregates
Sota Arakawa, Misako Tatsuuma, Naoya Sakatani +1
Understanding the heat transfer mechanism within dust aggregates is of great importance for many subjects in planetary science. We calculated the coordination number and the therma…
