The gravitational force balance point between the Earth and the Sun is known as the "Lagrange Point." Specifically, the Earth-Sun system has five Lagrange points, labeled L1 through L5. The point of interest for the balance of gravitational forces is typically L1, which is located between the Earth and the Sun.
L1 is approximately 1.5 million kilometers from Earth, or about 1% of the distance to the Sun. At this point, the gravitational forces exerted by the Earth and the Sun, as well as the centrifugal force experienced by an object at that point due to the rotation of the Earth and Sun, are in equilibrium. This makes L1 an ideal location for satellites monitoring solar activity, as they can maintain a stable position relative to both the Earth and the Sun.
It's worth noting that L1 is not a "fixed" point in space, as the gravitational influences of other bodies (such as the Moon) can have an effect. However, the concept of Lagrange points is crucial for understanding gravitational interactions in multi-body systems.
