It's believed that in addition to Earth, the terrestrial planets Mars and Venus may have had oceans soon after their formation.

The planet-hunting spacecraft went into orbit two years ago and a year later Laughlin decided to create price tags for the terrestrial planets that Keplar was set to discover.
两年前，美国宇航局的“开普勒”飞船进入轨道开始寻找类地行星。一年后，劳克林教授决定发明一种公式为“开普勒”发现的目标估价。

This could be the way terrestrial planets evolve and the Moon is begging us to go back and explore to figure that out.
这可能是类地行星的演化方式，月球正在期待我们回去探索，让真相水落石出”。

Several panel members have favored dividing planets into categories: terrestrial planets (Mercury, Venus, Earth, Mars), giant planets (Jupiter, Saturn, Uranus, Neptune) and a third class that would include Pluto.

Mr. ALAN STERN (Southwest Research Institute): And, you know, whereas we know of four terrestrial planets and four gas giants, we expect that there are hundreds if not thousands of these ice dwarfs, and so this class of planets which we have not yet reconnoitered is in reality the most populous class of planetary body in our solar system.

Dr. THOMMES: We had have ordered a few percent of systems that where the giant planets at least resemble the architecture in our own system, as to whether we would then have terrestrial planets in the habitable zone, the chances of that actually aren't too bad, because the terrestrial planets, we think, they kind of sprout like mushrooms pretty much anywhere.

类地行星
Our results showed all the terrestrial planets were in the typical fast prograde rotation state before 4.5 billion years, and the rotation states of Venus and Mercury remained steady before about 3.5 billion years.
结果更加有说服力的证明,在45亿年之前,所有的类地行星自转都可处在典型的快速正向自转状态,自转变化最大的是金星和水星,在大约35亿年前金星和水星的自转就可能稳定到目前状态。
