- Distances shorter than 1017 m
- 110,000,000 million km -- 12 light years -- Distance from Earth to Tau Ceti
- 1017m -- diameter of the Crab nebula (formed by a supernova)
- 2.6 × 1017m (27 light years) - distance from Earth to β Comae Berenices, a star approximately as bright as our sun. Its faintness gives us an idea how our sun would appear when viewed from even so close a distance as this.
