Planets with a large amount of mass.
Large planets have more gravity than smaller ones
The difference between large planets and small planets are that large planets are made up of gases and therefore don't have soild surfaces where as small planets are made up of rocks and other materials liek that and have soild surfaces.
GRAVITY... gravity means that objects are "attracted" to other objects, and the larger the object, the more GRAVITY will "attract" the object. The sun's gravity is too large for the planets to overcome.
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.
Planets have gravity because they have mass.
It is gravity that holds the planets in their orbits around the sun. Gravity is what gives "shape" to the solar system, to galaxies, and is the large-scale organizer of the universe as a whole.
The other planets do have gravity.
Yes. All planets have gravity. Earth is one of those inner planets.
No. Planets have gravity as a result of their own mass.
The premise of this question is incorrect; all planets have gravity.
Yes, dwarf planets can be round. Like regular planets, dwarf planets are large enough for their own gravity to pull them into a nearly spherical shape, making them round. Examples of round dwarf planets include Pluto and Eris.
the planets were formed by gravity because starts had gravity around them witch caused them to become bigger and be planets i think.. idk
