When was Jupiter discorved?

Answer 1

Because Jupiter is easily visible to the naked eye (you can see it without a telescope or binoculars) no one can say when or by whom it was discovered. It has been known since ancient times. To the Babylonians it represented their god Marduk. The Romans named it Jupiter (also called Jove) the prinicpal god of Roman mythology. Greek equivalent Zeus supplies the root zeno- used to form some Jupiter-related words, such as zenographic. The Chinese, Korean, Japanese, and Vietnamese referred to the planet as the wood star based on the Chinese Five Elements. Our best guess is that Jupiter was discovered by some of the first men in ancient times back when humans first started walking the earth.
