After five years of monitoring, astronomers in Europe have discovered a batch of three "super-Earths" orbiting a nearby star, and two other solar systems with small planets as well. Their findings, presented at a conference in France, suggest that Earth-like planets may be very common. It’s as if every single star harbor planets but the conclusive answer is not yet known but the astronomers are making huge progress towards it. The three super-Earths planets orbit a star slightly less massive than our Sun and this star is 42 light-years away towards the southern Doradus and Pictor constellations. One light-year is the distance light can travel in one year at a speed of 186,000 miles a second which is equivalent to 9.5 trillion kilometers. The three super-Earths planets are each bigger than the Earth. One is 4.2 times the mass of earth, the other is 6.7 times the mass of earth and the third planet is 9.4 times the mass of earth. They orbit their star at extremely rapid speeds. One of the planets is orbiting in just four days, compared with Earth's 365 days, the other planet is orbiting in just 10 days and the third is the slowest orbiting in 20 days.
