Nasa scientists in particular have found a planet in a multi - star system . 30 ##° b has four stars in its twenty - two pairs of binary stars . All binary stars would be visible from the planet , even in daylight . But its highly unlikely that the planet or any moons it has could host life . Discovery suggests that 4 % of sun - like stars are in quadruple orbits .
