Empty worlds

Can a planet be empty? No. Crashed ships reach every type but Waterworlds, and those have sunken ships instead. What a planet can lack is anything that pays a tool. A spot, below, is a place on a planet's grid that holds a building.

In charted systems, 11% of planets hold no tool source. Nearly all of those are Dead and Weird worlds and gas giants, and they still hold staff terminals.
In Uncharted systems, planets hold neither. A median one holds 0 spots, all wrecks.

Beyond the spots, any planet with water has fish to catch, as fishing lists by planet type, and one whose card shows Ancient Bones holds bone piles, whose fossils the Fossil Collector trades.

What each kind of planet can hold

No kind of planet is ruled out whole: every column has a yes. Gas giants hold no shop, monolith, or pillar, so they have no tool source. They are not empty, though: about 160,000 spots at the median, because the grid of a 523 km body is huge. Those spots follow the same rules as all the others, and we have not stood on a gas giant to check them.

Sea level

The grid does not care about water, but a building does. A spot at sea level or under it, up to 5 m above the water, stands empty.

24% of planets lose nothing to it. Where the rule bites, it bites hard: a median 30% of the grid gone. Lush worlds are the wettest, Dead and Weird worlds lose nothing. A few planets lose 90% or more.

Planets and moons of Euclid with at least one land spot in the grid, Waterworlds left out. Sea level means at sea level or under it, up to 5 m above the water.

Waterworlds

Sea level does not apply on a Waterworld, so they are counted apart: a median of about 7,100 spots, none lost to the water.

The opposite of an empty world is a dissonant one, where the rarest tools and ships wait: Sentinels and dissonance.
