What is one reason why it is very difficult to directly take a picture of an extrasolar planet?

Extrasolar planets are difficult to detect directly because they are small when viewed from Earth and light from the stars near them are brighter than they are

Explanation:An exoplanet or extrasolar planet is a planet outside the Solar System. The first possible evidence of an exoplanet was noted in 1917, but was not recognized as such. The first confirmation of detection occurred in 1992. This was followed by the confirmation of a different planet, originally detected in 1988. In addition to their tiny sizes, the light from the stars near the planets is much, much brighter than the planets themselves
