AN extraordinary solar system of seven Earth-sized planets orbiting a dwarf star could include at least three worlds on which life may have evolved, scientists believe.
The cool dim star, known as TRAPPIST-1, can be considered a close neighbour since it is only 39 light years away.
Six of its “exoplanets” lie in a temperate zone where surface temperatures range from zero to 100C. Of these, at least three are thought to be capable of having watery oceans, greatly increasing the likelihood of life.
No other star system known contains such a large number of Earth-sized and probably rocky planets.
