- India’s maiden solar mission Aditya-L1 reached the L1 point on January 6, 127 days after it was launched on September 2, 2023.
- After a 1.5-million km journey the spacecraft was placed in a halo orbit around L1.
- The orbit of Aditya-L1 spacecraft is a periodic halo orbit.
- It is located roughly 1.5 million km from earth on the continuously moving Sun–Earth line with an orbital period of about 177.86 earth days.
- This halo orbit is a periodic, three-dimensional orbit at L1 involving Sun, Earth and a spacecraft.
- The distance of L1 from the earth is approximately 1% of the earth-sun distance.
- There are currently four operational spacecraft at L1 which are WIND, Solar and Helio spheric Observatory (SOHO), Advanced Composition Explorer (ACE) and Deep Space Climate Observatory (DSCOVER).
