yes, but as for how many... no one knows since they are unknown
lol
I hope I answered your question!
There are eight planets and five dwarf planets in our solar system.
Other planets other than earth is put in the solar system for humans to explore and do researches on them.
It is very unlikely there are unknown planets in our system,, although beyond the kuiper belt, at the very far edge of our solar system some believe there may be another planet. It is referred to as "Planet X".
No, the planets after Pluto are still within our solar system. After Pluto, there is Eris, Haumea, Makemake, and several other dwarf planets and minor planets that are part of our solar system. Beyond these, there is the Kuiper Belt and the Oort Cloud which are also part of our solar system.
Planets outside our solar system are called exoplanets. Thousands of exoplanets have been discovered orbiting other stars in the Milky Way galaxy. They come in a variety of sizes and compositions, and many are quite different from the planets in our own solar system.
Currently there are 353 known extrasolar planets (that is to say, outside of our solar system), but it is unknown how many planets exist in the universe.
They could, but as of now, no astronauts have travelled to any other planets in the solar system.
New planets are more or less constantly being discovered outside the Solar system. There are almost certainly no unknown planets still lurking within the Solar system, though.
The atom and the solar system are not equal. The solar system contains the sun and the other planets.
Actually, there are 18 known planets in our solar system, as well as two known protoplanets. For a complete list of objects in the solar system, see the related links.
Planets have no purpose. They just "are".
9 P in the S S = 9 Planets in the Solar System
