Gravity is the force of attraction between objects that is due to their masses and the distances between them

Kepler found that objects that orbit the sun follow elliptical orbits. When an object follows an elliptical object around the sun, there is one point called aphelion where the object is farthest from the sun.

The current model of the solar system is the sun-centered or heliocentric model.

The solar system is located in the milky way galaxy/ Orion Spur

gravity has a force on the high tide and low tide because of the large force and pull

Until Galileo improved the telescope in 1609, people observed space with the naked eye.
To people who looked at the sky, it looked like the sun, moon, planets, and stars moved around the Earth.

The formation of the solar system is thought to have begun 4.6 billion years ago when a cloud of dust and gas collapsed.
