Venus, second planet from the Sun is often termed “Earth’s Twin Sister” because of their similarities in size, mass, density, bulk composition and gravity. It is believed that both planets share a common origin, forming at the same time out of a condensing nebulosity around 4.5 billion years ago. Due to its proximity to Earth, Venus has been a prime target for early interplanetary exploration. About 80 percent of the Venusian surface appears to have been shaped by volcanic activity. Venus has several times as many volcanoes as Earth, and it has 167 large volcanoes that are over 100 km across. The Indian Space Research Organization (ISRO) is looking at 2024 for launch of its mission ‘Shukrayaan’ to probe Venus instead of earlier schedule in June 2023 on account of COVID-19.
