Therefore, a large-scale survey that Ariel will perform is required to know more about exoplanets and exoplanetary systems.</span></span></span></span></span></span></p>

Exoplanets are not easy to detect since they are much less brighter than the stars they orbit and hence it is difficult to see them directly using telescopes.</span></span></span></span></span></span></p>
