NASA'S Spitzer space telescope has revealed the first known system of seven earth-sized planets around a single star.The planets are located in the habitable zone,the area around the parent star where the rocky planets are most likely to have liquid water.

The new discovery sets a record for the most habitable planets around one star.But all seven planets could have liquid water-but the chances are highest with the three in the habitable zone.

This system is called TRAPPIST-1.In may 2016,researchers announced that they discovered two planets in the system,then this year using NASA'S telescope Spitzer discovered five other planets,making the whole system.At about 40 light-years,the system planets are relatively close to us.
