No.
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.
Yes, all planets have gravity. Gravity is a force that attracts objects with mass towards each other, so every celestial body with mass, including planets, has its own gravitational pull.
Isaac Newton concluded that the force of gravity and the forward motion of the planets combined to keep them in orbit around the Sun. The force of gravity pulls the planets towards the Sun, while the forward motion of the planets creates the centrifugal force that counteracts gravity, leading to stable orbits.
"Gravity" is responsible for the existence of planetary orbits, and for their shapes and periods. It's also the reason for the spherical shapes of the planets, and for the existence of atmospheres, in the case of those planets that have any.
the planets would drift off into space in a straight line=========================================You're really asking "How would they move ...", because there is actuallyplenty of gravity in the solar system, and that's what keeps the planetsmoving in the way that they do move.If there were none, then a planet would sail off at a constant speed andin a straight line, forever.The answer may even be more complicated than that. Gravity is the mainthing that holds planets together. So without it, there probably wouldn'teven be any planets.Or stars.
Yes. Without the sun's gravity the planets would move out into interstellar space in straight lines.

Yes, gravity is present in a vacuum. If it weren't, planets wouldn't orbit the sun, moons wouldn't orbit planets ect.
No - without gravity, galaxies would not have formed, planets would not have formed, stars would not have formed.
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.
All planets have gravity, not just Earth.
Planets have gravity because they have mass.
-- 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.
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.

The other planets do have gravity.
