Are there planets that are better for life than Earth?

Comment

Trappist-1 is a red-dwarf star, the most common variety, located some 40 light-years away in Aquarius. In 2015, astronomers discovered that Trappist-1 was host to three earth-sized planets. Then it came under the spotlight again in 2017 when NASA scientists found an additional four planets, taking the total up to seven. This is the most terrestrial planets that have ever been found to orbit a single star, including our own Solar System. Trappist-1 is only fractionally larger than Jupiter in diameter. This image shows the star and six of the planets as they would appear from the vantage point of the fifth outermost planet, Trappist-1f. All of the planets and the Sun are to scale. One of the worlds is seen transiting in front of the star.
