Venus is known as the Earth's “Twin” because the planets are so like each other in size. The diameter(直径) of Venus is about 7,520 miles (12,100 km), 40 miles (644 km) smaller than that of the earth. No other planet comes closer to the earth than Venus. At its nearest appr...
New measurements of the Venus diameter in four wavelengths are presented. These measurements refer to phase angles between 92° and 145° completing those by other observers. No dependence on the wavelength of the diameter of the planet is found. The resulted value is : 16.86 ± 0.02 arcsec....

Fig. 1: Venus flytrap-inspired liquid metal-based logic module. a The Venus flytrap could generate an electric signal after receiving mechanical stimuli to sensory hair, leading to the increase of cytoplasmic calcium ([Ca2+]cyt) concentration. The strength of the electric signal gradually decreased...
For instance, a planet could lose its atmosphere with the consequence that liquid water would no longer be stable at its surface (similar to Mars), or a planet may have environmental conditions that are incompatible with the emergence of life (Venus, for instance). The observation of ...
Venus; Venusian clouds; acidity sensor; cloud droplet acidity; habitability of Venus1. Introduction Venus, with its surface temperature of 735 K and clouds composed primarily of sulfuric acid droplets has not been the most likely candidate for habitability research. While the surface of Venus may ...
Venus quick facts: Length of day:243 Earth days Length of year:225 Earth days Distance from sun:67 million miles (108 million kilometers) Number of moons:0 Surface temperature:900° F (480° C) Diameter:7,520 miles (12,100 km)
This work reviews the long-term evolution of the atmosphere of Venus, and modulation of its composition by interior/exterior cycling. The formation and evolution of Venus’s atmosphere, leading to contemporary surface conditions, remain hotly debated topics, and involve questions that tie into many ...
Our solar system consists of nine planets. The diameter of each planet, at its equator, is given here.aMercury 3,031 mi (4,878 km)bVenus 7,521 mi (12,104 km)cEarth 7,926 mi (12,756 km)dMars 4,222 mi (6,795 km)eJupiter 88,732 mi (142,800 km)fSaturn 74,565 mi (120,...
Abstract The lower cloud layer of Venus (47.5–50.5 km) is an exceptional target for exploration due to the favorable conditions for microbial life, including moderate temperatures and pressures (∼6...
