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 Kepler47 system(星系) does have two stars in its sky. It is about 5，000 lightyears 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 multiplestar(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 Kepler47 system because it is very hard for planets to form in such a difficult environment.
One of the planets, Kepler47b, is closer to the stars. It's three times larger than the Earth. The other one, Kepler47c, is about 4.5 times the size of the Earth. Most importantly, Kepler47c 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.
1.According to Paragraphs 2 and 3, the two stars in the Kepler47 system ________.
A. are similar to our sun in size B. are quite close to the Earth
C. are as bright as each other D. always move around one another
2.Which is TRUE about the planets in the Kepler47 system?
A. Kepler47b is five times as large as the Earth.
B. Kepler47b is farther away from the stars.
C. Kepler47c is neither too hot nor too cold.
D. Kepler47c is a good place for humans to go to.
3.The passage mainly tells us ________.
A. some facts about the Kepler47 system
B. the stars and planets of multiplestar systems
C. the different systems in space and their history
D. the special environment of our solar system
