On December 3, 2015, an Earth Swing-by operation of the asteroid explorer 'Hayabusa2' was performed. Several observatories successfully measured the brightness of 'Hayabusa2'. The variation of the apparent magnitude of 'Hayabusa2' measured during the swing-by is hard to explain using a simple hypothesis based on the distances of the observatories and 'Hayabusa2'.On December 3, 2015, an Earth Swing-by operation of the asteroid explorer 'Hayabusa2' was performed. Several observatories successfully measured the brightness of 'Hayabusa2'. The variation of the apparent magnitude of 'Hayabusa2' measured during the swing-by is hard to explain using a simple hypothesis based on the distances of the observatories and 'Hayabusa2'. In this paper, apparent magnitude of 'Hayabusa2' is estimated using modeling and rendering techniques based on computer graphics. The method is found to be useful to roughly estimate the variation of the magnitude, while more consideration is required to perform precise estimation.
