Trappist-1 and our Solar System to scale

In 2017 it was announced that we had detected 7 Earth-sized planets in the Trappist-1 system, 3 of which were in the star's habitable zone. This image shows how that solar system compares to our own solar system in size. The star is much smaller and redder and all 7 planets are roughly Earth-sized. The blue objects in the Trappist system indicate which objects may be habitable like the Earth.
