The mutual gravitational forces that attract a planet and the sun to each other
are responsible for keeping the planet in orbit around the sun.
Gravity plays a crucial role in both tides and planetary orbits. Tides are primarily caused by the gravitational pull of the Moon and, to a lesser extent, the Sun, which creates bulges of water on Earth, resulting in high and low tides. In planetary orbits, gravity governs the motion of celestial bodies, keeping planets in elliptical paths around stars, such as Earth's orbit around the Sun. The balance between gravitational attraction and the inertia of moving objects determines the stability of these orbits.
According to Kepler's laws of planetary motion, planetary orbits are in the shape of an ellipse with the Sun at one of the foci.
They all obey Kepler's 3 laws of planetary motion.
Gravity is the fundamental force that governs the motion of planets within a solar system. It acts as the attractive force between a planet and the star it orbits, keeping the planets in their elliptical paths. Additionally, gravity also influences the formation and structure of planets, contributing to their spherical shape and affecting their atmospheres and surface conditions. Overall, gravity is essential for maintaining the stability and dynamics of planetary systems.
Johannes Kepler is credited with forming the mathematics of elliptical orbits.
because without it we would not have the same gravity or we wouldn't stay on our axis

Gravity
Gravity is completely responsible for planetary motion. The shape and size of each orbit, and the speed of the planet at every point in its orbit, taken along with the mass of the sun, are completely determined by the behavior of gravity.
Projectile motion has two components horizontal motion and vertical motion. Gravity affects only the vertical motion of projectile motion.
Isaac Newton
He didn't alter them. He showed that his theory of planetary motion under gravity was consistent with them.
Sin no
Newton's three laws of motion describe how forces affect motion. They have nothing to do with gravity, except that gravity is one of many possible causes of force.
