Extraterrestrial liquid water
The Gliese 581 planetary system contains multiple planets that may be candidates for surface water, including Gliese 581c, Gliese 581d, might be warm enough for oceans if a greenhouse effect was operating, and Gliese 581e.
Asteroidal water
Asteroidal water are water or water precursor deposits such as hydroxide (OH) that exist in asteroids (i.e., small Solar System bodies (SSSBs) not explicitly in the subcategory of comets). The "snow line" of the Solar System lies outside of the main asteroid belt, and the majority of water is expected in Kuiper belt objects (KBOs) and minor planets. Nevertheless, a significant amount of water is also found inside the snow line, including in near-earth objects (NEOs).
