Gravitational pull gives planets their spheroidal shape (balanced by the outward push of matter, causing hydrostatic equilibrium) and also dictates their orbits, for example, their orbit around the Sun.
Gravity is determined by mass. Everything with mass has gravitational pull (including you). Planets with more mass have higher gravitational pulls
Yes. They all do - any mass, especially large masses like planets, have a gravitational acceleration that pulls things towards them!
Gravitational Pull?
Not only planets but everything with mass, no matter how large or small, has a gravitational effect.
the gas giant planets have strong gravitational pulls that hold on to their thick atmospheres. Additionally, the high escape velocity prevents the gases from escaping into space. The cold temperatures of these planets also help in maintaining the integrity of their atmospheres.
Allegedly, the gravitational forces of the planets have an effect on us here on earth.
the suns gravitational pull pulls them toward it but the planets try to escape its gravity
Mass & distance.
By causing them to rotate around the sun
The sun's gravity pulls the planets.
Planets revolve around the Sun due to gravitational force, which is strongest at the center of mass of a system. The Sun's immense gravity pulls the planets towards it, causing them to orbit around it in elliptical paths. This balance of gravitational forces keeps the planets in their orbits.
It may have something to do with the fact that the gravitational pulls are proportional to the masses of the earth and your teacher and that your teacher has considerably less mass than the earth!
