The Cats's Eye Nebula is a perfect example of a planetary nebula. See related link for a pictorial.
That depends what you include in the "Solar System". The Oort Cloud - a group of comets - is believed to be at a distance of about 1 light-year from the Sun; that would give a diameter of about 2 light-years. If you only include the 8 major planets, the size of the Solar System is only a fraction of a light-year. (A light-year is the distance light travels in a year; light gets from the Sun to the farthest planet in just a few hours.)
Oh, there are so many beautiful nebulas visible from Earth! You can see the Orion Nebula, the Lagoon Nebula, the Eagle Nebula, the Carina Nebula, just to name a few. Imagine all the lovely colors and shapes softly glowing in the night sky – it's truly a sight to behold and be inspired by. Keep looking up, and who knows what other wonders you might come across!
The Lagoon Nebula is located in the constellation Sagittarius. It is a prominent emission nebula and can be seen with the naked eye from a dark location.
Another popular nebula is the Eagle Nebula, also known as Messier 16. It is located in the constellation Serpens and is famous for the "Pillars of Creation," which are towering columns of interstellar gas and dust where new stars are forming.

Considering the distance to the Cats Eye Nebula is only 3,300 light years away, it is going to be within our own Milky Way Galaxy.

The eye of god is a Helix nebula. Close to a Planetary nebula.
Not "a" - it's the name of one specific planetary nebula. You can find pictures of it in Google Images.
Swan. To me, that doesn't rhyme. The answer may be the "prawn nebula".
The Cat's Eye Nebula [See Link] is a planetary nebula in the constellation of Draco.Observations with the Hubble Space Telescope revealed remarkable structures such as knots, jets and sinewy arc-like features.

The Cat's Eye Nebula appears in the constellation of Draco.
SN1987A was a supernova in the outskirts of the Tarantula Nebula. It could be seen with the naked eye from the Southern Hemisphere in 1987.
