8. Funny how you phrase it "your solar system"
There are eight planets in our solar system. However, in the entire cosmos, there are billions of planets that orbit stars in other solar systems.
9. Actually, there are 8 planets in our solar system. Pluto is no longer considered a planet. However, we have now found approx. 400 extra-solar planets, or planets in other star systems.
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.
In our universe there are billions of solar systems.
Maybe because if it's not, all the planets or many of the planets/solar systems/parts/the universe will be in jumble/disarray
We don't know for sure - Andromeda is just too far to see that small detail. However, from current understanding of solar system formation, there will be billions of solar systems, planets and probably life .
Since a galaxy can have many solar systems and a solar system might have more than one planet, for each galaxy there would be many planets. Therefore there would be more planets than galaxies.
There are nine planets in the solar system
Eight -mercury -Venus -earth -mars -jupiter -Saturn -Uranus -neptune
Mercury, Venus, Earth, and Mars are planets in our solar system that are made of rock. There may be many more in other star systems.
9 planets are in the solar planet.
