Tranppist-1 has more red color and much lower temperature than the Sun. Its size is only slightly larger than Jupiter and about 40 light-years from our Earth.

Here are 5 interesting features about the star system Trappist-1, "Solar System version 2.0".

1. "Solar System 2.0" Trappist-1 consists of 7 planets about the size of Earth.
