Detailed explanation-1: -Venus is often called “Earth’s twin” because they’re similar in size and structure, but Venus has extreme surface heat and a dense, toxic atmosphere. If the Sun were as tall as a typical front door, Earth and Venus would each be about the size of a nickel.
Detailed explanation-2: -The mesosphere of Venus extends from 65 km to 120 km in height, and the thermosphere begins at approximately 120 km, eventually reaching the upper limit of the atmosphere (exosphere) at about 220 to 350 km.
Detailed explanation-3: -Venus has the similar surface acceleration as well as the mass as that of the Earth. It implies that the radius will also be similar for both these planets. Therefore we can conclude that Venus has a similar size as that of the Earth.
Detailed explanation-4: -Venus has the most massive atmosphere of the terrestrial planets, which include Mercury, Earth, and Mars. Its gaseous envelope is composed of more than 96 percent carbon dioxide and 3.5 percent molecular nitrogen.
