Are there other planets in other solar systems?
Question:
Answer:
Currently there are 182 known "exoplanets". The large majority are Jupiter-sized or larger, and much closer to their Sun than the gas giants in our solar system are to our Sun. Thus, the term "hot Jupiter" is used to describe these, big close exoplanets.
While a variety of techniques exist to find exoplanets, the most common is looking for wobbles induced in the parent star by the planet's minor gravitational pull. This technique means that we're biased towards finding planets which induce large wobbles in their parent star. Large wobbles are produced by larger planets that are very close to their star...so the huge population of hot Jupiters we find is probably not representative of the true exoplanet distribution.
ya
yes
Yes alot
At least 210 extrasolar planets (those outside the Solar System) discovered to date (October 2006) most have masses which are about the same as, or larger than, Jupiter's the planets orbiting the stars Mu Arae, 55 Cancri and GJ 436 which are approximately Neptune-sized, and a planet orbiting Gliese 876 that is estimated to be about 6 to 8 times as massive as the Earth and is probably rocky in composition.
It is far from clear if the newly discovered large planets would resemble the gas giants in the Solar System or if they are of an entirely different type as yet unknown, like ammonia giants or carbon planets. In particular, some of the newly discovered planets, known as hot Jupiters, orbit extremely close to their parent stars, in nearly circular orbits. They therefore receive much more stellar radiation than the gas giants in the Solar System, which makes it questionable whether they are the same type of planet at all. There is also a class of hot Jupiters that orbit so close to their star that their atmospheres are slowly blown away in a comet-like tail: the Chthonian planets.
More than we know, they are just to far away to be discovered yet.
of course
scientists are saying yes with further investegating. maybe another world another universe. it is a mystery alright
DUH
Billions.
Yes. You might have heard of them. Mars, Venus, Saturn, Jupiter, to name a few.
Yes, other stars have planets orbitting them. The number we have cataloged keeps getting larger.
If you have a star and at least one planet orbitting it, you have a "solar system," and we've found dozens.
Yeah there's one called Proximus and no one knows about it except me as I was born there and I am an alien planning to take over the planet Earth. Don't tell your police/army/authorities because no one will believe you
Unless you can go there you will never know. God's creations are infinite!
yes, and sometimes they show up around here
god bless
yes closest to the Sun is Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune and pluto the solar system is located in the Milky way Galxy in space
As time goes on and we get better with technology we are discovering more and more planets. So the answer to your question is yes there are so many other planets out there it would make your head spin!! We just need better technology!
i'm 100% sure that there are ....imagine tha dimension of the universe...and the probability that rules in the universe..
i heard there are 200 of them.
