Yes, with sensitive instrumentation, almost two thousand planets outside the solar system (exoplanets) have been discovered - and even the first ones in another galaxy. (Note, the human eye cannot see exoplanets unassisted).
No planets in our solar system fit that description. There may be some outside our solar system that do, but we can't see those well enough yet to be able to tell.
Within our Solar System, no planet has more moons than Jupiter. [See related question] Outside of our Solar System, it is any ones guess.
There are no constellations in our solar system. All constellations you see are outside our solar system.
through a telescope :)
the reason you can see the planets in our solar system is because, they reflect the suns light off of their atmosphere or sufrace.
they are very far away
You see them by reflected sunlight.
No. All the stars you see at night are in our galaxy, but outside of the solar system. The only star in our solar system is the one at its center: the sun.
You cannot see planets outside our solar system with the naked eye. And, only a rare few can be seen with the most powerful telescopes. Most are detected by way of indirect measurements -- by observing their effect on their suns (stars).
Actually, there are 18 known planets in our solar system, as well as two known protoplanets. For a complete list of objects in the solar system, see the related links.
there is only 1 star in our solar system, which is our sun. the stars that we can see at night are outside of our solar system
