Wondering about “What is Lagrange Point 1?” It is a point in space and was discovered by Italian-French mathematician Joseph Louis Lagrange. This point is also referred to as the Lagrange Point (L1). It is an equilibrium point in space that lies 1.5 million kilometres between the Earth-Sun system. The Lagrange point L1 is one of the most significant points among other Lagrangian points for solar observation. After the success of Chandrayaan-3, ISRO’s upcoming Aditya L1 mission will be placed in the halo orbit around the Lagrange point L1 for observing the sun.

What is L1 in Aditya L1?
As you now know about Lagrange L1, you will think about What is L1 in Aditya L1? Aditya L1 is the India’s first solar mission. ISRO (Indian Space Research Organization) has revealed the Aditya L1 launch date and Time. The spacecraft will be launched on 2nd September 2023 at 11:50 AM (IST) from the Satish Dhawan Space Centre SHAR, Sriharikota.
The L1 is the point between the Sun-Earth where the Aditya L1 spacecraft will balance itself for studying the outermost layer i.e. chromosphere. The gravitational pull of the earth and sun at the L1 point equals the centripetal force experienced by the Aditya L1. This enables the spacecraft to stay in a stable position.

FAQs
The L1, L2 and L3 are the unstable Lagrange points among the 5 Lagrange point that lies along the line connecting two large celestial bodies such as the earth and the sun or earth and moon.
The Lagrange point L1 is 1.5 million km away from Earth. This is just 1 % of the distance between the Sun and the Earth. This point allows the spacecraft to hover since the gravitational pull of two celestial bodies at this point equals the centripetal force of the spacecraft.
No, the Aditya L1 solar spacecraft of the ISRO will not touch the sun. NASA’s Solar Parker Probe reached the closest to the sun’s surface i.e. 7.8 million kilometers from the sun’s surface.
Aditya L1 is the first ever India’s solar mission to study the sun’s outermost layer. This blog covers information about the point at which the spacecraft will be placed.
