The Moon is about 384,000 km from Earth, so even a tiny launch error becomes huge over such a long distance. If the spacecraft is aimed just 1° off course, the sideways error grows as it travels. Using d = Rsinθ the miss distance is 384,000 x sin1° = 6700km. This shows why missions like the Artemis program require extremely precise navigation.
