Aditya-L1 launch: What is Lagrange point, the location of ISRO's spacecraft on Sun?

Aditya L-1 has reached Sriharikota and is prepared for launch in the first week of September. "After the launch, it will take 125 days from the earth to reach Lagrange point 1 (L1). We have to wait till then," Somnath said.

The final date of the announcement is still not decided and will be fixed by Monday. The mission involves placing Aditya L1 in a set orbit from where it would be easy to observe different phenomenons on Sun's surface. It will be placed in a halo orbit around the Lagrange point (L1) of the Sun-Earth system.

The location is around 1.5 million km away from Earth. Before the final countdown of the space mission to Sun begins in September, know all about the orbit where Aditya L1 will be placed by ISRO. The Lagrange point L1 is located around 1.5 million km from the Earth.

Movement in the halo orbit around L1 point will let the satellite to continuously observe the Sun without any occulation/eclipses. Because of this, the scientists would be able to observe the solar activities and its effect on space weather in real time. L1 is among the five Lagrange points in the Earth-Sun system.

At this point, the gravitational forces of the two bodies balance the centrifugal force felt by a smaller object. Due to the balance of force, the object is not attracted by the Sun, hence would be able to effectively “hover" in a stable position relateve to the two larger bodies. Keeping in mind the gravitational forces of Earth and Sun, Lagrange Point 1 (L1) is located between the Earth and the Sun about 1.5 million kilometers away from Earth, in the direction of the Sun.

This point is located on the line connecting the two bodies. It is situated in the Earth's orbital path around the Sun. The spacecraft will carry seven
