SUMMARY
A 10 arc second accuracy is insufficient for sending objects to the Moon, as it translates to a positional error of approximately 20 kilometers at the Moon's average distance of 350,000 to 400,000 kilometers. This level of precision is roughly 1 in 20,000, which does not meet the stringent requirements for lunar missions. Accurate geocentric coordinates are critical for successful navigation and landing on the Moon.
