No, a planet's moons and atmosphere do not directly affect its gravity. Gravity is primarily determined by the mass of the planet itself; the more massive the planet, the stronger its gravitational pull. While moons can influence tidal forces and an atmosphere can affect pressure and weather, they do not change the fundamental gravitational force exerted by the planet.
Space does not have an atmosphere. It is generally considered a vacuum. Planets and some moons have atmospheres.
Yes, gravity affects celestial bodies such as planets, stars, and moons. Gravity is the force that causes objects with mass to be attracted to each other, keeping planets in orbit around stars and moons in orbit around planets. The strength of gravity between celestial bodies is determined by their masses and distances from each other.
Isaac Newton
The gas planets are much more massive than the terrestrial planets and therefore have stronger gravity. It is believed that as they formed many of their moons formed around them much like the planets formed around the sun. Other moons are likely captured asteroids and comets.
Planets and moons are both celestial bodies that orbit around a larger body, such as a star like the Sun. However, planets are typically larger in size, have more mass, and are able to support their own atmosphere, while moons are smaller and often lack an atmosphere of their own. Moons generally orbit around planets, while planets orbit around stars.
Gravity helps to keep the planets in orbit. It also helps to keep the moon's close to the planets.

They do not have the exact same color, mass, diameter, number of moons, atmosphere composition, name, or gravity.
The planets are satellites of the sun. The moons are satellites of the planets. The moons revolve around the planets captured by their gravity, while the planets revolve around the sun captured by its gravity and the sun.
If there was no gravity, the Sun and and the planets would never have formed.

false, meters are asteroids in the earth atmosphere
the gravitational pull of the gravity of the planet so in other words bigger planets more gravity, smaller planet less gravity. usually bigger planets have more moons
There is gravity. There is gravity on all planets, moons, and stars.
the planets do not orbit the moon but the moon orbits the planets because of gravity and inertia
There is no atmosphere on the moon. There is insufficient gravity to keep an atmosphere there.
Asteroids orbit the sun. Moons orbit planets and planets orbit the sun. So you could say the moons orbit the sun. However, moons are kept in their orbits by the gravity of their planet and planets are kept in orbit by the gravity of the sun. So in that sense, moons do not orbit the sun.
