Planetary orbits are a balance between gravity, which pulls them toward the Sun, and inertia that keeps them moving forward in the same direction as they are going now. Inertia causes the planets to keep moving just as before, but gravity pulls them toward the Sun. As the planets fall toward the Sun, the inertia (more properly called "momentum") keeps making the planet miss the Sun as it is falling.

Why do the planets all stay orbit around the sun and not drift on in an empty space?
Its because the gravitational field of the sun pulls the planets towards the sun and balances the intertia of the planets which make them want to move in a straight line.
What are the large objects in space that orbit a star such as the sun?
The answer is planets.
What would happpen to a space vehicle in orbit around Earth if it sped up?
If its speed was greater than the pull of gravity - it would simply leave orbit and drift off into space.
What will happen if planets do not follow their orbit around the sun?
planets will fall to the outer space ,they will collide with each other and they will melt or exploded
What makes the moon and a planet alike?
Both moons and planets are objects in space that orbit a larger body.

What is an orbit in outer space?
pathway that a celestial body follows. Planets, comets, asteroids orbit the Sun. Moons orbit their planets. The Solar System orbits the Galactic Center.It is the imaginary pathway that a body in space follows as it moves around another body. The earth and the other planets orbit the sun, and various moons orbit their host planets.
How does earth revolve in space?
the sun holds the planets in orbit.
What are the large objects in space that orbit a star such as the sun?
The answer is planets.
Why do the plantes orbit the sun?
why do the PLANETS orbit the sun? Because of gravity, the sun has loads of gravity so it holds all the planets in space.
Dose all the planets orbit the sun?
All the planets in our solar system orbit our sun. Recently other suns, far out in Space, have been discovered to have their own planets.
How many ways do planets move?
they can orbit or rotate around in space
How do planets only orbit around the sun and not go everywhere in space?
The Sun's gravity pulls on the planets.
Are the eight planets under the sun or above it?
Neither. The eight planets orbit the sun, but in space there is no "under" or "over."
What would happpen to a space vehicle in orbit around Earth if it sped up?
If its speed was greater than the pull of gravity - it would simply leave orbit and drift off into space.
Is a satellite a space probe?
A space probe is not the same as a satellite, because they can orbit planets and sat elites don't.
What is the difference between a planet and other space objects?
To qualify as a planet, a body has to be approximately round, it has to orbit the sun and it has to have cleared its orbit of all other objects - so that at that distance from the sun, there are no other sizable bodies. Some dwarf planets, like Pluto, fulfill the first two requirements, but not the last one, this is why they are deemed dwarf planets rather than planets.
