Terminal World other brother, Opportunity, founded Fortune's Landing. This refers to the Mars Exploration Rover mission. The ages of characters, given in years, also imply that either they mature much more quickly than present-day humans, or that the year is much longer than 365 days (which if the planet is Mars will be the case since a Mars year is 687 Earth days). It is said that people once lived to be twice as long as now, which makes Mars such a good fit. There are also references to people in the past being similar in size to children; this could indicate
Gliese 687 40% of the Sun's mass and nearly 50% of the Sun's radius. Compared to the Sun, it has a slightly higher proportion of elements with higher atomic numbers than helium. It appears to have a rotation of 60 days and to be somewhat chromospherically active. It displays no excess of infrared radiation that would indicate orbiting dust. It is known to have a planet, Gliese 687 b, with a mass of 18.394 Earth masses (which makes it comparable to Neptune), an orbital period of 38.14 days, and a low orbital eccentricity. Gliese 687 is a solitary red dwarf that emits
