is there more planets beyond the nine we know of?

Question

tell me about them

Answer 1

krypton

Answer 2

We know of some 350,000 asteroids and minor planets in the Solar System, Four hundred years ago, before Galileo trained his telescope on Jupiter, we thought there were only 8 bodies in the Solar System in all (The Sun, the Moon, Mercury, Venus, Earth, Mars, Jupiter & Saturn) That is how far we have come in 400 years of using telescopes!

But only two out of these newly discovered bodies are large enough to be regarded as planets, Uranus, discovered in 1781 and Neptune, discovered in 1846.

The idea that the points of light we can see in the Milky Way might be stars like our Sun and that some of them might have planets around them, some of which might harbour life, was first proposed by the Greek philosopher Democritus, 2,500 years ago

Answer 3

We only know of eight now, as Pluto is no longer considered a planet. And the answer is no, as far as we know there are no other planets orbiting the sun. But there are vast numbers of smaller bodies, including Pluto, Eris, Sedna and others yet to be named. And increasing numbers of planets are being discovered in orbit around other stars, it's only a matter of time before we detect radio/TV signals from life elsewhere, and they detect ours.

Answer 4

Several extra-solar planets (planets outside our own solar system) have been discovered. Most of these are gas giants more massive than Jupiter. A startlingly large number of them orbit extremely closely to their parent star, giving them the nickname, "hot Jupiters." We also know of a rocky planet 14 times as massive as the Earth. This one was dubbed a "super-earth."

Answer 5

When the official number of planets was changed to eight, it was because there are several rocks of similar size to Pluto, including Charon and Ceres and one that used to be nicknamed Xena, but got an official greek name I can't remember.

Also, extrasolar (planets orbiting other suns) have been observed.

Answer 6

I guess there are but we haven't develope the technology to study them, with the passing of the years there will be more interesting and exciting discoveries.

Answer 7

Billions and billions. Tell you about them, got a few years of time to spare. I don't.
