Trappist-1 Solar System
A prime example of other life sustaining planets in our Milky Way Galaxy is the Trappist-1 Solar System. Trappist-1, also designated as 2MASS J23062928-0502285, is a dwarf star that is slightly larger and much more massive than the planet Jupiter. It is about 40 light- years from our Sun in the constellation Aquarius. What is amazing is that 7 rocky, Earth-sized planets orbit this star.
This illustration shows the seven Earth-size planets of TRAPPIST-1, an exo-planet system about 40 light-years away, based on data current as of February 2018. The image shows the planets relative sizes but does not represent their orbits to scale. The art highlights possibilities for how the surfaces of these intriguing worlds might look based on their newly-calculated properties.
The seven planets of TRAPPIST-1 are all Earth-sized and terrestrial. TRAPPIST-1 is an ultra-cool dwarf star in the constellation Aquarius, and its planets orbit very close to it. [Description by NASA scientists]
