Expert Answer:

Gravity is the gravitational force experienced by a given mass in presence of another
huge mass like mass of planet, mass of moon, mass of sun etc.

This gravitational force is expressed as F = (G×M×m)/R2 ,
 
where G is universal gravitational constant, m is the given mass that experience gravitational force
in presence of huge Mass M and R is the distance between masses.
 
Gravitational force experienced by unit mass (acceleration due to gravity)
on surface of huge masses like earth, moon and sun are given below
 
For Earth :-  Mass = 6×1024 kg ,   Radius = 6371 km,  acceleration due to gravity on earth's surface = 9.8 m/s2
For Moon :-  Mass = 7.3×1022 kg, Radius = 1740 km,  acceleration due to gravity on moon's surface = 1.6 m/s2
For Sun :- Mass = 2×1030 kg, Radius = 7×105 km,  acceleration due to gravity on moon's surface = 271 m/s2
 
In nutshell, to create gravity, you need a huge mass like mass of earth, mass of moon, mass of sun etc.
Nearby this huge mass you feel gravity
