By means of the comparison between dynamical figures of Venus and the Earth, we confirmed that the nonhydrostatic moment difference ratios of the two celestial bodies are approximately equal. The hydrostatic flattening of the external equipotential surface of Venus according to the theory of internal ...
随着技术的发展,更多的探测器如美国的“麦哲伦号”探测器也对金星进行了详细的雷达成像,帮助科学家们更好地理解这颗行星的表面特征和地质活动。 六、金星与地球的比较 (Comparison Between Venus and Earth) 金星与地球在许多方面有相似之处,但又有显著的差异。两者的大小、质量和组成都很相似,但金星的环境条件却极...
This is a flowchart summary of the histories of the terrestrial planet atmospheres (Venus, Earth, and Mars). It shows the histories side-by-side so it is easier to compare the planet histories. The chart for Venus up to the dashed arrow describes the runaway greenhouse process that ...
Venus is often referred to as Earth's "sister planet". With a mass of 4.8676×1024 kg, a surface area of 4.60 x 108 km², and a volume of 9.28×1011 km3, Venus is 81.5% as massive as Earth, and has 90% of itssurface areaand 86.6% of its volume. ...
Lavas on Earth and the Moon that flow this readily typically consist of basalts, and so it is probable that basalts are common on the plains of Venus as well. Of the many types of lava-flow features seen on the Venusian plains, none are more remarkable than the long, sinuous canali. ...
Venus and Earth have long been considered sister planets. The reason for this comparison is that they are similar in size, mass, and age. The diameter of Venus at its equator is about 7,500 miles (12,000 kilometers). The planet revolves around the Sun at an average distance of 67 ...
an atmosphere that is incredibly dense (92 times that of Earth, in fact) and reaches temperatures that are hot enough to melt lead. In addition, the planet’s rotation is immensely slow by comparison, taking 243.025 days to complete a single rotation, and rotating backwards relative to Earth...
A Southwest Research Institute-led team has modeled the early impact history of Venus to explain how Earth’s sister planet has maintained a youthful surface despite lacking plate tectonics. Through a comparison of the early collision histories of Earth and Venus, it’s believed that Ve...
It has been shown that Venus can have an internal solid core only if the composition of the planet is very different from that of Earth. Comparison of the observed values of the moment of inertia and tidal Love numberk2with model values allowed us to conclude that the radius of the core ...
