Orginalna vijest 2 dio. One star, a red dwarf called GJ 1214, which is about 42 light-years from Earth, repeatably dimmed for 52 minutes every 1.6 days, indicating a planet with a orbit of 1.6 days. The group calculated that it had a radius of 12% of that of the star, which is roughly 2.7 times the size of the Earth. The drag caused by the planet on GJ 1214 allowed the group to calculate its density, of 1.9 g cm-3, compared to 5.5 g cm-3 to the Earth\'s, which suggests that because water\'s density is 1 g cm-3 , the planet is a mixture of rock and water, with other trace gases.
