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...:)
They are held within the gravitational grip of the sun.

Gravity
everthing is weightless in space.
There is gravity in space. Gravity is what makes orbits possible.
Gravity holds the planets in their orbit
the planets would not receive heat from the sun and all life on earth would cease to exist. also the planets would not rotate or be held in place. the sun is what holds the planets together in orbit.
The Sun`s gravity holds all the planets in orbit in space.The gravitational attraction from our Sun.
everthing is weightless in space.
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.
There is gravity in space. Gravity is what makes orbits possible.
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
Because the suns orbit holds the earth and all of the other planets in place.
If they aren't in space, then where else can they be?
