Light from the stars they orbit makes it difficult to see them.
Rocks are to geologists as stars are to astronomers.
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.

Dwarf stars are actually very abundant in the universe, but they can be more difficult to observe because they are fainter and cooler than other types of stars. Astronomers use specialized techniques and instruments to detect dwarf stars, but they can still be challenging to study due to their dimness. Additionally, dwarf stars may not stand out as much in crowded regions of space where brighter stars and other celestial objects dominate the view.

Rocks are to geologists as stars are to astronomers.
Astronomers believe that stars, planets, and other celestial objects are 'born' in nebulae. Nebulae are vast clouds of gas and dust in space that can eventually collapse under their own gravity to form new celestial bodies. This process of stellar birth is essential for the formation and evolution of galaxies.
Astronomers do. Also, theoretical physicists and cosmologists, as well as anybody who's interested.

extra solar planets are not bright compared to the stars they orbit
