and is completely shrouded by dense cloud. The atmosphere is principally carbon dioxide. Mean distance from sun: 108 million km; period of revolution around sun: 225 days; period of axial rotation: 244.3 days (retrograde motion); diameter and mass: 96.5 and 81.5 per cent that of earth respec...
As Venus was closer to the earth,its parallax angle would be larger,and Halley worked out that by using Venus it would be possible to measure the sun's distance to 1 part in 500. is it possuble to describe parallax to me? 是什么意思?

The planet revolves around the Sun at an average distance of 67 million miles (107 million kilometers). It takes Venus about 225 Earth days to complete one revolution. The planet spins extremely slowly on its axis, taking about 243 Earth days to complete one rotation. Like Uranus and Pluto...
respectively) vary little from the mean distance. The period of its orbit—that is, the length of the Venusian year—is 224.7 Earth days. As Venus and Earth revolve around the Sun, the distance between them varies from a minimum of about 42 million km (26 million miles) to a maximum of...
Venus is the secondplanetfrom theSun, and the closest toEarth’s orbital path. It is a rocky planet, and its size, structure, and chemical composition is similar to that of Earth. For this reason, Venus is often called Earth’s twin. ...
Now we need to know for sure. There is, after all, only so much we can do with ground-based instruments. Venus is extremely bright. This brightness, caused by the intense reflection of sunlight from its thick clouds and highlighted because of its closer distance to Earth, basically blinds ...
Venus is the second planet from the Sun, which orbits around the Sun every 224 Earth days. It has the longest rotational period (243 days) of any planet in the Solar System, and rotates in the opposite direction to most other planets. It does not have an
Venus is the 2nd planet from the sun and theclosest to the Earth. So,how far away is Venus? Venus is at a distance of around25 million miles (40 million kilometers)from the Earth, but theactual distance depends on the position of both Earth and Venus in their own orbits. ...
Venus is the second planet in our solar system close to the Sun. Venus can cast shadows and on rare occasion, visible to the attention in broad daylight. After the Moon, it is the second-brightest natural object in Earth's night sky.
