It doesn't seem very far, since both Pearl and Lapis look at a cluster of stars rather close to earth, and say that they are almost there. My guess is that Homeworld is only a Galaxy away from Earth's, and that Lapis with her gem powers, managed to get there in a year. A year because Steven is shown going through Winter, Spring, Summer and Fall. This is just my guess, but it seems to make sense. OK, I shouldn't be commenting on this, it is just a show for fun. It's all fantasy, etc. etc.

However astronomy is one of my main hobbies, and I used to teach, so I cannot restrain myself.

Please don't take this as a personal criticism JinxBlinx, I am really just concerned at how poor educational systems seem to be these days.

Galaxies are huge bodies of millions of stars, or more, that are tens of thousands of years across. Our galaxy, the Milky Way, is particularily large. It has over 200 billion stars and is between 100,000 and 200,000 light years across. The nearest other galaxy is currently believed to be the Sagittarius Dwarf Spheroidal Galaxy and is at a distance of something like 70,000 light years from Earth.

I assume you meant the nearest planetary system, which would be Alpha Centauri at 4 light years, so, if Lapis took a year to get there, then she was traveling at 4 times the speed of light. Those are some wings.

For those who are interested 2 planets have been observed now at Alpha Centauri, but they have not been confirmed with follow up observations.

Sorry, I do go on sometimes.
