RESEARCHERS today said they discovered a batch of three "super-Earths" orbiting a nearby star, and two other solar systems with small planets as well.
They said their findings, presented at a conference in France, suggest that Earth-like planets may be very common.
"Does every single star harbour planets and, if yes, how many?" asked Michel Mayor of Switzerland's Geneva Observatory.
"We may not yet know the answer but we are making huge progress towards it," Mr Mayor said in a tatement.
