We do everything we can to keep ourselves away from the sun in summer. Some wear hats, others buy umbrellas or sit under trees. But can you imagine what it would be like to have two suns over your head?

Well, the Kepler?47 system(星系) does have two stars in its sky. It is about 5,000 light?years away from us. One of the stars is similar to our sun, but the other is much smaller and less than 1 percent as bright.

In fact, systems with two stars are quite common. “Unlike our sun, many stars are part of multiple?star(多个恒星的) systems where two or more stars move around one another,” said a scientist from NASA's Research Center in the US.

Scientists are more surprised that there could be two planets in the Kepler?47 system because it is very hard for planets to form in such a difficult environment.

One of the planets, Kepler?47b, is closer to the stars. It's three times larger than the Earth. The other one, Kepler?47c, is about 4.5 times the size of the Earth. Most importantly, Kepler?47c is neither too close nor(既不……也不……) too far away from the stars. It means the planet won't be too hot or cold. So, scientists believe there could be water on it or even life.
