light from the they orbit makes it difficult to locate extrasolar planets with telescope
extra solar planets are not bright compared to the stars they orbit
Astronomers cannot locate extrasolar planets with telescopes because these planets are outside of our solar system and too far away for telescopes to directly observe. Instead, astronomers use indirect methods such as radial velocity and transit techniques to detect these distant planets.
To - minimise the distortion of the received image due to light pollution.
Astronomers recognize 88 official constellations, which form the basis for dividing the sky into different regions to help locate and identify stars and celestial objects.

Planets are considerably smaller than their parent stars, also they emit no light and are very close to the star. With all this combined, separating between the two with a telescope is very difficult.
Light from the stars they orbit makes it difficult to see them.
extrasolar planers are not bright compared to the stars they orbit For approximately the same reason that it's difficult to spot a mosquito circling a street light that is 5 miles away, with a telescope.

Two reasons. (1) Such planets are very dim, from our point of view. Some of the planets in our own Solar System look roughly as bright as the brightest stars; now imagine them at least 100,000 times farther - that would make them 10 billion times dimmer, from our point of view. (2) Such planets are very close to their star - once again, from our point of view, i.e., considering the angular distance.
