Yes, the sun is indeed attracted to the planets through its gravitational force, which plays a fundamental role in keeping the planets in their orbits around it. This gravitational attraction between the sun and the planets is responsible for maintaining the delicate balance required for the stability and harmony of our solar system.
Gravitational force, as famously explained by Sir Isaac Newton in his law of universal gravitation, is a force of attraction between two objects with mass. In the case of the sun and the planets, the sun’s massive size and the planets’ comparatively smaller masses create a gravitational pull that keeps them bound in their respective orbits. As Newton eloquently put it, “I have explained the phenomena of the heavens and of our sea by the force of gravity, but I have not yet assigned a cause to gravity.”
Here are some interesting facts about the gravitational relationship between the sun and the planets:
-
The sun, with its immense mass, exerts a gravitational force that is approximately 28 times stronger on Earth than the moon’s gravitational pull.
-
While the sun’s gravitational force affects all the planets, the strength of the force varies based on the mass and distance of each planet from the sun. The closer a planet is to the sun, the stronger the gravitational force it experiences.
-
The planets also exert gravitational forces on the sun, albeit significantly weaker due to their smaller masses. However, this reciprocal pull causes the sun to experience slight fluctuations in its position, a phenomena known as “barycenter motion.”
-
The sun’s gravitational force not only keeps the planets in their orbits but also plays a crucial role in shaping their paths and influencing their orbital velocities.

Earth 5.97 x 10^24
Mars 6.42 x 10^23
Jupiter 1.89 x 10^27
Saturn 5.69 x 10^26
Uranus 8.68 x 10^25
Neptune 1.02 x 10^26

In conclusion, the sun’s gravitational force not only attracts the planets but also plays a pivotal role in maintaining the delicate equilibrium and order of our solar system. This celestial dance of gravitational forces continues to captivate scientists and astronomers as we strive to unravel the mysteries of our cosmic neighborhood. As astrophysicist Carl Sagan once said, “Somewhere, something incredible is waiting to be known.”
See a video about the subject.
This YouTube video explores the concept of gravity and its application in explaining why the Earth doesn’t crash into the Sun. By using the equation F = Gm1m2/R^2, historical examples are given to demonstrate the successful use of gravity in predicting celestial events. The video then explains that objects can be launched with sufficient velocity to create an orbit, where they constantly fall towards the Earth but never reach its surface. This circular orbit prevents the Earth from colliding with the Sun. However, without proper control, the Earth’s orbit may eventually slow down and spiral back towards the Sun. This explanation applies not only to the Earth but also to other planets and their moons in the solar system.

Because the Sun is the largest, most massive object in our solar system, it also has the strongest gravitational force in our solar system. It pulls every one of the planets (and everything else) toward its center of mass.
Thus Hooke postulated mutual attractions between the Sun and planets, in a way that increased with nearness to the attracting body, together with a principle of linear inertia.
