Would there be a sky without gravity?
No, as there would be no coalescence of matter to form suns and planets without gravity.
Does any other planet have gravity?
Yes. All planets have gravity.
How does the sun stay in orbit?
The Sun stays in orbit because of gravity. This is also why all the planets stay in orbit too. Gravity pulls the planets towards the Sun. Without gravity, the planets would be wandering all over the universe.
Why do the moons stay in orbit around Jupiter?
Any moon is held in orbit by gravity, just as the planets are held in orbit around the sun by gravity.
What were the two factors Isaac Newton concluded that combined to keep the planets in orbit?
1) The gravitational attraction between the planets and the Sun. 2) The "inertia" of the planets. That's their tendency to move in a straight line unless a force (gravity in this case) acts on them.

Does any other planet have gravity?
Yes. All planets have gravity.
Does the sun hold the planets in orbit with its gravity?
Yes. Without the sun's gravity the planets would move out into interstellar space in straight lines.
Can gravity consist without air?
Yes, gravity is present in a vacuum. If it weren't, planets wouldn't orbit the sun, moons wouldn't orbit planets ect.

Could the universe have formed without gravity?
No - without gravity, galaxies would not have formed, planets would not have formed, stars would not have formed.
Why do the moons stay in orbit around Jupiter?
Any moon is held in orbit by gravity, just as the planets are held in orbit around the sun by gravity.
What impact does gravity have on the planets and their orbit?
Without gravity, each of the planets would continue straight ahead into space, and become dispersed. Gravity holds them in their orbital paths around the Sun. Of course, without gravity, the Sun would explode, and the planets would also disintegrate and their mass would scatter because of the centrifugal force of their spin and angular momentum.
Where do the planets get gravity?
Planets have gravity because they have mass.
Why is there only gravity on earth and not any other planet?
All planets have gravity, not just Earth.
What is the gravity af all of the planets in cm?
-- There is no such thing as the gravity of all the planets. Each planet has its own number, which is different from any other. -- Gravity can't be described in units of cm.
Why don't any other planets have any air and gravity?
All planets have gravity- Some more than Earth, some less. Other planets that are large enough do have air- but not made up of the same gasses as Earth.
