We have been investigating the differences in the way the Moon is seen in Australia and Japan (parallax). Using parallax, we can determine the distance to the Moon. We took photographs of the Moon in Sydney and Japan at the same time. We confirmed that the moon seen in each of the images taken was slightly different, and the parallax was found to be about 0.5 degree. On the other hand, if we determine the parallax using the known data of 380,000 km distance to the Moon, we obtain a theoretical value of 0.56. Therefore, there was no significant difference between the parallax we obtained and the theoretical value. Since we were unable to obtain an accurate parallax this time because the images were unclear, we would like to improve the accuracy by reviewing the imaging technique and other factors.
