Apple ships some nice-looking Earth and Moon wallpapers with iOS, but there are 7 other planets who deserve some attention as well, so I've gone ahead and made them all myself using high resolution imagery from NASA. As you'd expect, these are all very high resolution, and will look good on an iPhone with 2x as many pixels, so they should be relately future-proofed. Enjoy!

Download all 8 in a single ZIP.

And here is each planet if you just want one:

• Mercury
• Venus
• Earth
• Mars
• Jupiter
• Saturn
• Uranus
• Neptune
