定位原文: F段2、3句“Johann…” 解题思路: 显然对应文章F段出现的数字,通过阅读F段前五行,可以找出reasonably accurate 对应 a fair degree of accuracy, a value for the AU “天文单位的数值”, 即太阳到地球的距离,对应distance of the Sun from the Earth。所以此题应选D。 Question 19 答案: A 关键...
(vee -nŭs) The second planet of the Solar System in outward succession from the Sun and the one that comes closest to the Earth. It orbits the Sun every 224.7 days at a distance varying between 0.72 and 0.73 AU. It has a size (12 104 km equatorial diameter), density, and, probabl...
Another nearby public transport station is the Pengkalan Raja Tun Uda Bus Terminal, which is also within walking distance from Venus Female Boarding House. This terminal offers a wide range of bus services, connecting you to different parts of Penang and even other cities in Malaysia. Whether ...

About a century later, Edmund Halley proposed that the distance from the Earth to the Sun (which was then unknown and is defined as one astronomical unit, AU) could be measured by observing transits of Venus across the Sun. These transits occur in pairs separated by eight years at intervals...
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 orbits the Sun at an average distance (semi-major axis) of108,208,000 km (0.723 AUs), ranging between 107,477,000 km (0.718 AU) at perihelion and 108,939,000 km (0.728 AU) at aphelion. This makes Venus’ orbit the least eccentric of all the planets in the Solar System. In...
AU (Astronomical Unit) = distance of the Earth from the Sun ( paragraph B) 所以答案是: D (Johann Franz Encke) Question 19: He understood that the distance of the Sun from the Earth could be worked out by comparing observations of a transit. In paragraph B, “He realised that from dif...
The mean orbital distance of Venus from the Sun is about 0.72 AU or 108 million km and completes an orbit every 224.7 days. All the planets within the system orbit the Sun in an anticlockwise direction as viewed from above Earth’s the North Pole. Venus rotation is different as compared ...
Venus is sometimes characterized as Earth's 'twin' because of its close proximity in solar system location ( 0.72 AU heliocentric distance compared to 1.0 AU) and its similar size ( 6053 km radius compared to 6371 km radius), but other close resemblances are few. Besides the more obvious ...
