What exactly do you mean by "in space"? Everything is in space.
If you meant why they are individually floating without getting attracted into the corresponding star, then that is due to the centrifugal force caused by the revolution of the planet.
Please append the corrected question to this answer if you happen to read this again...:)
Planets are held in orbit around a star by gravity. Gravity is the force of attraction between objects with mass, and it is what keeps planets in their respective orbits around stars like our Sun. Without gravity, planets would not be able to maintain their position in space.
Planets are held in their orbits by the gravitational force exerted by the sun. This force is what allows planets to stay in motion around the sun without flying off into space or falling into the sun.
Planets are held in orbit around the Sun by the force of gravity. Gravity is the attractive force between two objects with mass, and the Sun's immense mass keeps the planets in their orbits.
Although not yet proven, it is believed that their is a massive black hole at the center of each galaxy.
The space between planets is known as interplanetary space. It is mostly vacuum but can contain small amounts of particles and gases.
The sun's gravity holds the planets in their orbits. It also holds other space objects in their orbits, such as asteroids.
the sun holds the planets in orbit.
Because the mass of the planet holds it down.
My teacher Mrs. Black said before that it was gravity that holds the planets together in space.
because the stars gravity pulls them in and holds them in orbit
why do the PLANETS orbit the sun? Because of gravity, the sun has loads of gravity so it holds all the planets in space.
Because the suns orbit holds the earth and all of the other planets in place.
we have outer space because what else is going to hold the planets up and not let them fall forever, that's what our sun does, and outer space holds the sun up
