Humans have only visited the moon so far....sorry to disappoint but we are observers.

So far, with current technology, yes. Note that the nearest stars are in the order of 10,000 to 100,000 times farther than the planets in our own Solar System. You might imagine a technology that allows astronauts to travel to such other star systems, but that would require enormous technological breakthroughs, and the trip may well take generations - or require the astronauts to be put in some sort of artificial hybernation - another technological breakthrough we haven't achieved yet.
So far, none. The only way we've been able to observe it so far is by powerful telescopes.
Sheer distance. We are talking about millions and millions of miles alone between Earth and Mars. When you factor in the distance between other planets, like from Jupiter to Saturn, the expanse of space only grows. It takes time to travel that far.
No astronaut has travelled to a different planet. If they were to do so it would be for exploration and exploitation. Astronauts are known to explore and travel for the benefit of the others.
So far all the noon landing astronauts were astronauts not artists.
It's possible that other planets have life - and even intelligent life - and that we simply don't know about them yet. Not many planets have been explored so far.
Astronauts go to different planets etc and collect specimens and other things so that scientists can research and find out more about our solar system.
So far most planets are too hot or too cold to support life or are gas giants. Scientists are yet to find signs of life in other planets, other than planet Earth. The universe has many galaxies and planets, most are still yet to be explored. The search for extraterrestrial life is ongoing.
So far. Jupiter and Saturn

None have been found so far.
Most planets that have so far been discovered have had gaseous atmospheres.
So far the 12 astronauts who walked on the moon were all Americans, no Arab has gone or walked on the moon.
As far as I can imagine, No. Astronauts and space shuttles are tiny with respect to the planets. Mostly,space shuttles are in between two orbits. To observe planets revolving around the sun, you need to be very far away (so that you can see this view. Think of this: If you are standing in the middle of the track of a gigantic circular race track,would you be able to see all the cars moving around the race track? No. You would just be able to see the cars zooming in front of you. And it would appear as though the cars are moving straight. You would only be able to see all the cars moving round the enormous track if you were on a helicopter, or sitting on a seat high above the track. This is exactly the same thing with the planets. You can't see them all revolve unless you are really far away.And, astronauts don't go that far out.
None so far.
Well,planets do not have any light of their own so they are definitely not brighter and yes there may be some stars smaller than the planets but most of the stars are bigger than the planets . But on the whole the Space is not that much explored so that we can get any cumulative answer.
