who discovered all the planets?

Answer 1

I believe we still in the process of discovering new planets.

Answer 2

For each planet here are the discoverers:

1. Mercury: Mercury has been observed for thousands of years, and I believe the Babylonians are credited with mentioning it in writing for the first time some 3000 years ago or so. We do not know the name of the individual who first discovered it, just as we do not know the name of the man/woman who invented the wheel.

2. Venus: Because Venus is so bright, the first caveman who went outside at dusk or dawn surely noticed it. The ancient Greeks knew enough about it to know that it was different from other "stars". Mercury, Mars, Jupiter, and Saturn were also known to the ancients. This probably includes among many others the Chinese, Babylonian, and early American cultures which were relatively sophisticated. Galileo in 1610 was first to observe that Venus had a visible disk and that it had phases like the moon so perhaps he could be considered to have discovered the modern Venus. Captain James Cook made observations of a "Transit of Venus" in 1776-1779.

3. Earth: hahahaha..unknown?

4. Mars: Mars is much like Venus-- it's very bright and therefore easily spotted in the night sky. Because of this, we don't know who exactly discovered Mars. We do know it was named after the Roman god of war, because its reddish color reminded people of blood

5. Jupiter: Jupiter is the largest planet in our solar system. It is also one of the brighter objects in the night sky. No one knows for sure who discovered Jupiter, but we know the ancient Greeks named him after the god, Zeus.

6. Saturn: Like the inner planets and Jupiter, Saturn is clearly visible in the night sky. The ancient Greeks named the planet after the god of agriculture and time. It wasn't until 1655, however, that we knew Saturn had rings. Galileo saw two lumps on either side of Saturn, be he didn't know what they were. The astronomer Christian Huygens later found out they were rings

7. Uranus: It was discovered by William Herschel in 1781

8. Neptune: Neptune was discovered on September 23, 1846 by Johann Gottfried Galle, of the Berlin Observatory

9. Pluto (it is no longer considered a planet as of 2006) but it was discovery by Clyde Tombaugh in 1930

Answer 3

most of the planets were discoverd in the early 1600's by astronomers. the most recent was pluto in the 1930's

Answer 4

I wont tell, but he started it all. His name starts with a J and he got in trouble with the church because of his findings. Through out history many have found new planets and their still being found today.

Answer 6

Answer 7
