None in the solar system itself, but over 500 trillion in the rest of the universe.
The solar system is not part of any other star system. It is part of a galaxy called Milky Way.
There are no galaxies in our, or any other, solar system. They are far too large.
They are in all three. Planets are in solar systems. There are lots of solar systems in a galaxy. There are lots of galaxies in the universe. So any planet is in a solar system, a galaxy and the universe.
No, we have not seen any evidence of a black hole in our solar system.
Solar System: The sun with the celestial bodies that revolve around it in its gravitational field. Galaxy: A collection of star systems; any of the billions of systems each having many stars and nebulae and dust.
The solar system is only a small part of a galaxy. The Milky Way, galazy in which our solar system is found, has other solar systems.
500 light years from our solar system, in any direction, you're still deep within the Milky Way galaxy, and on a scale of galaxy-size, still relatively near our solar system.
The orbital plane of a stellar system can be oriented in any way in relation to the plane of the Milky Way Galaxy. Our solar system, for example, is almost perpendicular to the plane of the Milky Way Galaxy.
No, there is nothing to "float" in. Like just about any object in outer space, the Solar System ORBITS the center of the Milky Way; it is moving in "free fall", meaning that gravity is the only force of any significance acting on the Solar System.
These are the basics. Our sun is the star at the center of our solar system. A solar system is made up of a star and any other objects connected to it by its gravity. Our sun has the standard eight planets along with their moons, and also countless other objects including asteroids and comets. Our galaxy, The Milky Way, is estimated to contain between 200 billion and 400 billion stars. Some of those stars have planets orbiting them, and others do not. Our solar system then is just a very very tiny part of the Milky Way, and the Milky Way is one of billions of observable galaxies throughout space.
Yes. Our solar system is part of the Milky Way galaxy.
Saturn has more moons than any other planet in our solar system
