The first exoplanet was discovered in 1992, but the floodgates really opened in 2009, with the launch of Kepler, a planet-hunting space probe.Thousands have since been found. Statistics suggest that every star in the galaxy——and, presumably, the universe——has at least one. 译文 首个系...

At that distance, surface temperatures would be suitable for liquid water, a condition believed to be important for life.C D )21. The newly-found planet is Earth. A. smaller than B. as big as C. the same as D. much bigger than CD)22. Kepler is the name of A. the planet B. a...
Soon thereafter, Tycho Brahe, Kepler, Galileo, and Newton provided observational and theoretical support that ultimately demoted the Earth from the central object in the universe into a mere planet; the change in the status of the Earth occurred in parallel with the promotion of the Sun into ...
According to Kepler's third law,the orbital period T of a planet is related to the radius R of itsorbit by T2 R3.A planet's orbit is larger than Earth's by a factor if4.97.What is the planet's orbital period?(Earth's orbital period is 1 yr.) 相关知识点: 试题来源: 解析 T ...
2. The following picture is from NASA 3, which shows the Goldilocks Zone around Earth and an extrasolar planet known as Kepler 22b. As you can see from the image, both Mars and Earth are in the zone, but life as we know it only exists on Earth. Venus misses out on being in the...
Scientists have discovered a new planet that is similar to the earth. The planet, called Kepler-186f, is slightly (no more than 10%)larger than ours and probably has seasons like the earth does. But while this news is exciting, there is a lot that we still don’t know about Kepler-18...
At the time of its discovery, it had the longest period of any small planet in the habitable zone of a multi-planet system. Because of its long period, only four transits were observed during Kepler's interval of observations. It was initially missed by the Kepler pipeline, but the first...
of interest in this book, which shows how the concept of 'planet' has evolved throughout history. As a professional interested in this topic, I found the historical narrative quite illuminating and useful."—Gibor Basri, University of California, Berkeley and Co-Investigator, NASA's Kepler ...
故选E。【小题2】根据下文“However, in 2015 NASA’s Kepler space telescope found its first Earth-sized planet in a “habitable” zone. ”(然而,2015年美国航天总局的开普勒太空望远镜在一个“宜居”区域发现了第一颗地球大小的行星)可推知,大多数系外行星和太阳系的行星不同。B. Most exoplanets are ...
