It is mainly due to the vast distances involved, compared with the relative small size of the planet.
To put it into perspective, a planet in orbit around a star 10 light years away (relatively close for a star) is 60 trillion miles away (60,000,000,000,000). The distance of Neptune (furthest planet in our solar system) is around 3.7 billion miles away (3,700,000,000). So the Exoplanet in this example is roughly 16000 times that distance.
The brightness of the star also overwhelms the nearby planets in orbit around it. Planets are much smaller than stars and tend not to emit light.
What else can I help you with?
Are there moons orbiting planets in other solar systems?
Most likely there are. But just detecting the presence of the 'extra-solar' planets is so delicate and difficult, we don't have the ability yet to detect the presence of their satellites.
Are planetary systems around stars extremely rare?
No, although it is difficult to spot exoplanets, so only the larger ones are often found. Most systems with identified planets most likely have many other smaller planets that we cant detect. A planet the size of Earth or Mercury is nearly impossible to detect with current technology.
Is there a solar system that has 8 planets besides ours?
Other stars, other than our own, have had multiple planets detected in an orbit around them. Its highly likely that there are other systems with eight planets. Planets the size of mercury or even slightly bigger planets the size of the Earth are extremely difficult to detect, so a star with four or five large known planets may actually have a lot more planets.
What are some purple planets from other solar systems?
We do not know. Although we have detected planets in other solar systems, we do not know what colors they are.
How do astronomers observe planets that are too far away to see?
Space Telescopes Planets that are orbiting stars that are far away creating fluctuations in the light that we see coming from the star. Astronomers can observe those planets by measuring the fluctuations of that light.

Why do you suppose all the other sun like systems we know about have only 1 huge planet within 2 AU of its star?
We currently have the ability only to detect large planets that are close to their parent star, but as the technology progresses, we will be able to detect smaller planets, and planets that are further away. Also, astronomers have found systems of planets, meaning stars that have more than 1 planet.
Which galaxy are planets in?
It is possible that every galaxy has some planets. We just are starting to detect some planets in other galaxies.

How people know that there are other planets?
Because we can see the nearest planets through telescopes and for those much further away we can detect them by their effect on other planets and stars.
How do astronomers observe planets that are too far away to see?
Space Telescopes Planets that are orbiting stars that are far away creating fluctuations in the light that we see coming from the star. Astronomers can observe those planets by measuring the fluctuations of that light.
Why is it only recently that planets in other solar systems have been discovered?
Other solar systems are extremely distant from us, and are correspondingly difficult to view in detail. We are constantly devising new and more powerful telescopes, and new astronomical observation methods, with which to see what we have not previously seen.
What is the biggest planet in the map?
The biggest planet observed directly is Jupiter. Planets have been discovered near other stars, and they tend to be large as well, maybe because the smaller ones are difficult to detect.
Is there life on other planets is there any similar to earth?
Astronomers have found Earth-sized planets in other solar systems.
Can you detect all types of radar with a radar detector?
You can detect most types of radar itself,but you need other detectors for other systems.
