Which planet other than earth has gravity?

Answer 1

Every speck of mass in the Universe 'has gravity'. That includes every planet, comet,

asteroid, meteoroid, moon, artificial satellite, space ship, star, grain of dust, person,

car, dog, dish, shoe, goldfish, doorknob, rock, computer, soda can, cellphone, and the

lint in every pocket. Every one of them 'has gravity'.

Answer 2

All of them; in fact, everything that has mass, has gravity. The force of gravity is defined by Newton's Universal Law of Gravitation in Classical Mechanics. This law states: F=G(m1m2)/r2

where:

F is the gravitational force between two bodies,

G is the Gravitational Constant, 6.6726 x 10-11m3/kg/s2 ,

m1 is the mass of the first object (in kg)

m2 is the mass of the second object (in kg)

r is the distance between the two object (in meters)

The gravitational acceleration of an object toward another object is calculated with the equation: a= (-(G*M)/r2)

where:

a is the acceleration to the center of mass of the attracting body

G is the Gravitational Constant, 6.6726 x 10-11m3/kg/s2 ,

M is the attracting mass

r is the distance between the two objects

is the unit vector from the center of mass of the attracting object to the center of mass of the object being attracted.

Answer 3

All planets in our solar system have gravity. Some planets like Jupiter and Saturn have stronger gravity than Earth, while others like Mars and Mercury have weaker gravity.
