which planet was invented first?

Answer 1

I think the word "discovered" should only be used for Uranus and Neptune (and Pluto) as they were the only ones that involved either chance discovery (Uranus) or looking for and searching for them and then finding them (Neptune and Pluto) (and also Ceres).

The rest were simply noticed as existing, recognised as having something in common (they visibly moved) and then regarded as planets, once that concept had been formulated.

The Greek word "planetes" means wanderer and the ancients noticed that five of the brighter lights in the skies did not have fixed positions like the rest did but wandered to and fro, hither and thither, and regarded them as different because they were in motion and the rest were not.

These were Mercury, Venus, Mars, Jupiter and Saturn. They also regarded the Moon and the Sun as planetes as they too changed their position as against the "fixed stars" in the firmament.

Earth was not, at the outset, RECOGNISED as a planet like the others because it was thought (wrongly) that it stayed still and was the centre of the known universe.

Only with the advent of a heliocentric model of the Solar System, placing the Sun at the centre, not the earth, as proposed by Copernicus in 1543 did the earth become recognised as a planet, and when it was, the Sun and the Moon were derecognised as planets. The term planet had acquired a new meaning: "revolves around the Sun". The Moon did not, and plainly the Sun did not revolve around itself, so they could no longer be regarded as planets,

So the answer is: 7 celestial bodies, Mercury, Venus, Mars, Jupiter, Saturn. the Moon and the Sun were all regarded as planets from antiquity, Only after 1543 did the Earth become regarded as a planet, and Uranus and Neptune were not discovered until 1781 and 1846 respectively as they were not bright enough to be found without the aid of a telecope.

As Bob Dylan once remarked "you don't need a Weatherman to know which way the wind blows" and nobody needed an astronomer to discover any of these seven bodies for them. All you had to do was look up at the heavens.

Answer 2

Planets were, of course, not "invented"; they have been around since long before people (over four billion years). Earth, of course, was discovered first, since it is under foot all the time. Which of the visible planets was discovered next is unknown, but it was probably either Venus or Jupiter because they are the brightest.

Answer 3

Planets were discovered, not invented. And I believe that the first planet to be discovered was Venus, because Venus has been used for navigational purposes by ancient cultures.

Answer 4

I don't think planets are "invented" but I imagine Earth was the first with a name...

Answer 5

Planets were, and are not, invented. They are "discovered" by scientists. They're already out there but we have only found them fairly recently, with the advent of the telescope. As technology gets more and more sophisticated, we may have the capability to discover more planets around us.

Answer 6

Planets were not invented

Answer 7

I'm going to assume you mean "Discovered, of course, and not "invented" It would depend on which era you're looking at. Officially I beleive they discovered them in the 1800's once astronomy was no longer considered herasy. Before that, Ancient Egypt, ancient Greece- they've all got records of planets, sometimes all 9.

Answer 8

If you mean "formed or created" then after the big explosion I think all planets were formed at the same time and took some time to orbit in a constant orbit
If you mean "Discovered" then I don't know exactly which one but I know that Venus was known along time ago because it can be seen by naked eye in certain times of the day

Answer 9

"Invented" implies an idea based on inspiration leading to the realization of a tangible thing, like Edison inventing the lightbulb.

Even staunch creationists generally don't go so far as to call the Creator an "inventor", since the inspiration, experiment, and trial-and-error implicit in invention are all non-omniprescient and non-omnipotent characteristics inconsistent with godhead.

Answer 10

No planet can ever be 'invented'. It can only be discovered. I hope you realise the difference between the two words.
