马克罗·斯塔特制作的视频《我们的太阳系中不同行星的规模比较》可视化地探索了我们太阳系内天体的巨大尺寸差异。该视频突出了包括地球、木星和土星在内的各种行星,强调相对于地球而言,每个行星的实际大小与屏幕上的表示有效传达了其庞大的体积。通过将其与更大气态巨行星如木星和土星进行对比,视频展示了令人惊叹的场景...
Planetary SystemGiant PlanetProtoplanetary DiskA comparison of solar system properties to experimental data derived from observations of exoplanets results in a significant revision of the accretion theory. We describe some new ideas of the present-day theory of the origin of planets and planetary ...
cross through our planet's atmosphere each day. Astronomers have recorded more than 800 comets passing through the inner part of the solar system. Billions more, however, lie in the area surrounding the solar system, in the far reaches of the swarm of comets known as the Oort cloud or in...
By comparison, the terrestrial planets have meager atmospheres at best. A planet's ability to retain an atmosphere depends on its temperature and mass. Simply stated, a gas molecule can "evaporate" from a planet if it reaches a speed known as the escape velocity. For Earth, this velocity is...
The Jovian planets have very thick atmospheres consisting of varying amounts of hydrogen, helium, methane, and ammonia. By comparison, the terrestrial planets have meager atmospheres at best. A planet’s ability to retain an atmosphere depends on its temperature and mass. Simply stated, a gas mo...
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...

Re-creating the solar system with modeling clay may seem like an easy enough endeavor; many of us learned how to roll clay into a ball long before we were able to speak in sentences. But creating an accurate representation of the solar system is much mor
