Xerojenix: Maybe try starting again.
If all the humans that ever lived throughout history played the game from birth to death and lived for 100 years, spending 5 minutes to discover each new planet, it'd still take them 3 and a half lifetimes to collectively visit every planet.
Not all of those 18 quintillion will be near game start locations, but you'd be unlucky for this to keep happening.
However, this was a known part of the game, so ...

I'm just going to point this out to stop that overblown and very exaggerated number from continuing to be used:
There are 256 unique galaxies. When you go through the Centre (not to) on the last Galaxy you are transported to the same Galaxy 256 with a new name, but you can prove it to be the same Galaxy by going to planets discovered while in the last Galaxy (256).
There is no where near 18quintillion planets.
There are 256 unique galaxies.
Each Galaxy goes to a sector count of 0FFE,0FFE,0FFE (4095 counting sector 0,0,0). A large number of those sectors around the Centre are not populated with selectable star systems and left as empty space.
Each sector of space has a number of solar systems. The highest Valid solar System Index I have encountered was around 600 (a valid SolarSystemIndex value is one where the solar system shows on the GalacticMap).
Each Solar system has up to 6 planets.
256 Galaxies * 4095 X Sectors * 4095 Y sectors * 4095 Z sectors * 1000 Solar Systems * 6 planets = at best 105 Quadrillion which is a major factor away from 18 Quintillion
18,000,000,000,000,000,000
-105,475,825,728,000,000
=
17,894,524,174,272,000,000 planets short of 18 Quintillion
That is using the most generous form of the math that includes sectors where there are no selectable solar systems and has a 400 buffer over the highest valid solar system index noted so far. Even if you were to include the
Invalid SolarSystemIndex values (which do create solar systems that have planets) your best amount is 431.9 Quadrillion which is still 17.56 Quintillion short. That is with each Solar System having 6 planets which we know is not the case.
Even if we double the number due to the planets being different in Normal/Creative versus Survival/Permadeath that leads to still being short by over 17.13 Quintillion planets.
