Indian Mission Aditya L-1 is related to which of the following ?

The correct answer is Sun.Aditya or Aditya-L1 is a spacecraft mission to study the Sun.​The Aditya-1 mission was conceived as a 400kg class satellite carrying one payload, the Visible Emission Line Coronagraph (VELC) and was PLANNED to LAUNCH in an 800 km low earth orbit. A Satellite placed in the halo orbit around the Lagrangian point 1 (L1) of the Sun-Earth system has the major advantage of CONTINUOUSLY viewing the Sun without any occultation/ eclipses. Therefore, the Aditya-1 mission has now been revised to “Aditya-L1 mission” and will be inserted in a halo orbit around the L1, which is 1.5 million km from the Earth. The satellite carries additional six payloads with enhanced science scope and objectives.The project is approved and the satellite will be launched during the 2022 timeframe by PSLV-XL from Sriharikota.​Aditya-1 was meant to observe only the solar corona. The outer layers of the Sun, extending to thousands of km above the disc (photosphere) is termed as the corona. It has a temperature of more than a million DEGREE Kelvin which is much higher than the solar disc temperature of around 6000K.
