Long day point.
This is the balance point of the gravitational forces of the sun and the earth. Under the combined action of the gravitational forces of the sun and the earth, the telescope can just obtain the centripetal force required to move synchronously with the earth.
On December 25, 2021, the James Webb Space Telescope was launched aboard a European Ariane 5 rocket.
