Asteroid Ryugu observed with the Thermal Infrared Imager (TIR).
The images were captured between 16:02 – 23:45 JST on June 30, 2018 and were taken every eight minutes
for one rotation. From the 20 km altitude (home position), one pixel is about 20 m in size.
The distance to the Sun at this time is 0.987 au (1 au is about 149.6 million km, the average annular
distance between the Sun and the Earth). The scale bar shows relative temperature
(the values have no meaning). Red indicates a high temperature while blue is for colder temperatures.
2018-10-09. Correction: 1 au distance is corrected as 149.6 million km.
