KEY POINTS:
European researchers say they have discovered a batch of three "super-Earths" orbiting a nearby star, and two other solar systems with small planets as well.
The trio of planets orbit a star slightly less massive than our Sun, 42 light-years away towards the southern Doradus and Pictor constellations. The planets are bigger than Earth - one is 4.2 times the mass, one is 6.7 times and the third is 9.4 times.
