Its mass.
More mass=more gravity
Also the distance from the planet's center
to its surface, i.e. its radius.
Gravity, together with the planet's total kinetic and potential energy, completely determines the size and shape of the orbit.
Your weight on a planet is determined by the strength of its gravity. Gravity is the force that pulls objects towards the planet's center. The more massive the planet, the stronger the gravity, resulting in a greater weight for objects on its surface.
Yes, gravity plays a significant role in preventing gases from escaping a planet's atmosphere. The strength of a planet's gravity determines the escape velocity required for gases to break free from the planet's gravitational pull. Planets with higher gravity, like Earth, are able to retain gases more effectively compared to those with weaker gravity.
Io is a moon of Jupiter, not a planet. Surface gravity is about 18% of the gravity on Earth.
Mercury, because it's the smallest if you don't consider Pluto to be a planet.
The force of gravity is determined by the masses of the objects and their distance apart.

It's mainly to do with the mass of the planet, the more mass, the higher the gravitational pull of the planet. The two are related.

The more gravity something has, the more gravity it has. A planet, like Jupiter, can have 30-something moons because of it's large mass. And the solar system exists only because the sun has so much mass it generates gravity for all the planets.
Yes, gravity is what determines the shape of a planet's orbit around a star. Depending on the initial conditions of the planet, the orbit can be circular, elliptical, or another shape, but gravity is always the force that governs the path of the planet.
The weight of an object on the surface of a planet depends on ...-- The mass of the object.-- The mass of the planet.-- The distance between the center of the object and the centerof the planet, i.e. the planet's radius.
The particles of rock and dust that the Earth much later would be made from had gravity. Much, much, much later, the planet was formed. Every object that has mass also has gravititational attraction, even your body. Even a sewing needle has gravity.
No. It is the other way around; gravity depends on mass.
Yes it does but not as much as earth does. Every object that has mass also has gravity.
the sun's gravity pulls the planets towards it but the other planet's gravity helps keep the planet not get sucked towards the sun. With gravity working this creates the planet to orbit the sun
