Venus is the second planet from the Sun, and Earth's closest planetary neighbor. Venus is the third brightest object in the sky after the Sun and Moon. Venus spins slowly in the opposite direction from most planets. Venus is similar in structure and size to Earth, and is sometimes called Earth's evil twin.

Despite the emphasis on Venus of early space exploration (Mariner, Venera, Vega, & Pioneer), and the more recent Magellan, Venus Express, and Akatsuki Missions, Venus remains a global mystery. Sitting in our own planetary back yard, Venus represents an unusual example of terrestrial planet formation and evolution that obviously differs from Earth a...
EnVision, a low-altitude polar orbiter, was selected in 2022 as ESA's M5 mission in its Space Science Cosmic Vision Program. The mission is currently in phase B1, and the adoption is scheduled for January/February 2024. EnVision will carry 5 instruments and 1 experiment(an S-band Synthetic Aperture Radar, a Subsurface Radar, 3 spectrometers and a r...
Further Venus exploration to find the causes of differences between Earth and Venus is crucial to understanding how the Solar System works and the conditions for planet formation and the emergence of life. This is of particular relevance in this era of discovery and characterisation of a variety of terrestrial planets in other stellar systems and d...
Venus accounts for 40% of the mass of terrestrial planets in our solar system, yet even fundamental parameters such as the relative size of its core to mantle are unknown. As we expand the scope of planetary science to include those planets around other stars, the lack of measurements for basic planetary properties such as moment of inertia, whethe...
Venus features are named after females goddesses, mythological heroines and famous women in international history (poets, writers, artists, scientists) by the International Astronomical Union’s (IAU) Working Group for Planetary System Nomenclature, with the exception of Alpha Regio, Beta Regio, and Maxwell Montes named after James Clerk Maxwell (18...
ems, planets, and of life itself, is at the heart of this quest. The three terrestrial planets in our solar system - Earth, Mars, and Venus - show a wide range of evolutionary pathways, and so repr. nt a “key” to our understanding of planets and exoplanets. Earth and Venus were born as twins – formed at around the same.
The planet is nearly as big around as Earth – 7,521 miles (12,104 kilometers) across, versus 7,926 miles (12,756 kilometers) for Earth. From Earth, Venus is the brightest object in the night sky after our own Moon. The ancients, therefore, gave it great importance in their cultures, even thinking it was two objects: a morning star and an ...
Mar 2, 2015 · Understanding why Venus and Earth became so different will help us understand why Earth evolved as it has and what the range of conditions for similarly sized worlds around other stars may be. Venus provides the contrast to the Earth that can help us both better understand the origins of our world’s characteristics and the range of possibilities for similar sized planets orbiting other stars.
Jan 1, 2007 · Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 176. With the search for extra-solar planets in full gear, it has become essential to gain a more detailed understanding of the evolution of the other earth-like planets in our own solar system. Space missions to Venus, including the Soviet Veneras, Pioneer Venus, and Magellan, provided a wealth of ...
