While similarly sized planets have been found before, the latest one, known as Kepler-452b, is circling a star that is very similar but older than the sun at a distance about the same as Earth’s orbit. “It’s great progress in finding a planet like Earth that is similar in size and...
Kepler-452b Observation Candidates must follow up observations and analyses to show that they are actual planets . However , Kepler-452b was identified by the Kepler space telescope , and its discovery was announced by NASA on 23 July 2015 .`` We`ve been able to fully automate our process ...
2. 答案 D根据第四段中的Kepler-452b is 6 bill ion years old(our Sun is about 4.5 billion year s old), has the same temperature, and is 20 percent brighter and has a diameter 10 percen t larger.可知,Kepler-452b比太阳先存在15亿 年。 3. 答案 B根据最后一段中的Kepler-452b provi des...
While Kepler-452b is larger than Earth, its 385-day orbit is only 5 percent longer. The planet is 5 percent farther from its parent star Kepler-452 than Earth is from the Sun. Kepler-452 is 6 billion years old, 1.5 billion years older than our sun, has the same temperature, and is...
