The L1 point, or Lagrange Point 1, is a unique location in space situated about 1.5 million kilometers from Earth toward the Sun, along the line connecting the Earth and the Sun. At this point, the gravitational forces of the Earth and the Sun, combined with the orbital motion of a smaller object, balance out so that the object can maintain a stable position relative to both bodies. This means an object at L1 orbits the Sun with the same period as the Earth, effectively "hovering" between the Earth and the Sun

. This makes L1 an ideal spot for spacecraft that need an uninterrupted view of the Sun, such as the Solar and Heliospheric Observatory (SOHO) and India's Aditya-L1 solar mission. These spacecraft can continuously monitor solar activity and provide early warnings of solar storms that might affect Earth

. In summary, the L1 point is located on the Earth-Sun line, approximately 1.5 million kilometers from Earth toward the Sun, where gravitational and orbital forces create a stable equilibrium for spacecraft
