Properties of the planets are identified - such as size, spin rate, and distance from the sun - that are important in understanding the characteristics of their atmospheres. Venus, earth and Mars have surface-temperature differences only partly explained by the decrease of solar radiation flux with...
size as the Earth. The planets go around a dwarf star (矮星) called Trappist-1. It is much smaller and cooler than our Sun. They are about 40 light years (光年) from the Earth. 27.___But scientists say it's a little close.28.___If you lived on one of them, you could possibl...
Just as astronomers disagree with one another as to the distance of the planets, so also are they at odds in determining their sizes, as is evident from Book I, Chapter 25. Thus Tycho Brahe asserted that Saturn is at least twenty-two times larger than the earth while Riccioli said it ...
It was the first planet visited by a spacecraft (Mariner 2) and the first to be successfully landed on (Venera 7) but the first detailed maps were not possible until the arrival of Magellan in 1991. Diameter: 7,521 miles or 12,104 km Distance from Sun: 0.7 AU Day: 241 Earth ...
Alpha Centauri, triple star system, the faintest component of which, Proxima Centauri, is the closest star to the Sun, about 4.2 light-years distant. The two brighter components, called A and B, about 0.2 light-year farther from the Sun, revolve around each other with a period of about ...

relatively small size选项对应第三段第二句，应该属于类地行星的； contain选项对应第四段最后一句，属于类木行星的；temperatures选项对应第五段第三句，温度越高，逃逸速度越小，聚集气体的能力越差，所以应该属于类地行星的；density选项有一定迷惑性，原文第四段说类地行星密度大类木行星密度小，说的是类木行星...
