Explanation:

Aditya L1 will be ISRO’s first ever solar mission to be launched in 2019. L1 in Aditya L1 represents Lagrangian points named after famous mathematician of 18th century Louis Lagrange. Langrangian Point L1 is among those 5 lagrangian points between earth and sun where the gravitational pull of earth (not the moon) and sun equals the centrifugal force exercised by a small mass body in its orbit. Hence, 2nd statement is incorrect and rest are correct statements.
