The speculation of the existence of life on Venus has decreased significantly since the 1960s, when spacecraft began studying Venus and it became clear that the conditions on Venus are extreme compared to those on Earth. The fact that Venus is located closer to the Sun than Earth, raising te...
Since the 1960s, astronomers have been aware that Venus’ atmosphere behaves much differently that those of other terrestrial planets. Whereas Earth and Mars have atmospheres that co-rotate at approximately the same speed as the planet, Venus’ atmosphere can reach speeds of more than 360 km/h ...
The Orbit Inclination is 3.39 degrees, that is how much the orbit deviates from the orbital plane. The volume of Venus at the equator is 92.843. The Escape Velocity, the speed which is need to break free is 10.36 kilometers per second. The Surface Gravity of Venus is 8.87 compared to Ea...
Its mapping mission, and subsequent aero-braking experiments, completed, Magellan was programmed to lower its orbit one last time on 11 October 1994. As planned, atmospheric drag slowed the spacecraft below orbital speed, causing it to re-enter and be destroyed. Last contact was made on 12 Oc...
The speed of the zonal westward wind increases with altitude and reaches ~ 100 m/s (mean value) near the cloud top altitude (Khatuntsev et al. 2013; Hueso et al. 2015). Several generation mechanisms of superrotation have been proposed by many authors (Leovy 1973; Gierasch 1975; Rossow ...
On the other hand, the wind speed becomes increasingly slower as the elevation from the surface decreases, with the breeze barely reaching the speed of 10 km/h (2.8 m/s) on the surface (DK Space Encyclopedia: Atmosphere of Venus p 58). Near the poles are anticyclonic structures called ...
Orbital Period: In Venus’ case, things work a little differently. For starters, it orbits the Sun at an average distance of about 0.72 AU (108,000,000 km; 67,000,000 mi) with almost no eccentricity. In fact, with its farthest orbit (aphelion) of 0.728 AU (108,939,000 km) and cl...
Venus orbital period (a year) lasts about 225 Earth days, and a sidereal day (rotation in retrograde motion) lasts about 243 Earth days1. Venus is similar to Earth in terms of size (0.95 of Earth’s radius), mass (0.814 of Earth’s), bulk density (0.95 of Earth’s), and gravity ...
Another common phenomena is Venus' strong winds, which reach speeds of up to 85 m/s (300 km/h; 186.4 mph) at the cloud tops and circle the planet every four to five Earth days. At this speed, these winds move up to 60 times the speed of the planet's rotation, whereas Earth's ...
