The gravity we experience on Earth does not come from the Sun. Gravity is a force that attracts any two objects with mass toward each other. The greater the mass of an object, the stronger its gravitational pull. In our solar system, the Sun has the greatest mass, so it exerts the strongest gravitational force. However, the Earth also has a significant mass, so it too exerts a gravitational force. The pull of gravity between the Sun and the Earth is what keeps our planet in orbit around the Sun.

The gravity we feel on Earth is primarily due to the Earth's own mass. The Earth's gravity is about 9.8 m/s², meaning that every second, objects fall towards the Earth at a rate of 9.8 meters per second. The Sun's gravity is also pulling on the Earth, but its effect is much smaller than the Earth's gravity. The Sun's gravity is about 0.006 m/s², meaning that it pulls the Earth towards it at a rate of only 0.006 meters per second. This is why we do not feel the Sun's gravity as strongly as we feel the Earth's gravity.

So, while the Sun's gravity does have a slight effect on the Earth's orbit, it is not the main source of the gravity that we experience on Earth. The gravity that keeps us grounded to the Earth comes primarily from the Earth's own mass.
