Note that the meridional circulation is much lower than the zonal circulation, which transports heat between the day and night sides of the planet. All winds on Venus are ultimately driven by convection. [3] Hot air rises in the equatorial zone, where solar heating is concentrated and flows to the poles.
Questions on the effect of obliquity in super-rotation on Titan is often compared to Venus, as they share similar centrifugal accelerations to achieve dynamic balance. Any seasonal variations effected by obliquity between Titan and Venus is much different, as the small obliquity of Venus at 2.7° negates any strong seasonal effects.
The reason for this is that when Venus is closest to Earth, it is between the Earth and the Sun, so we see only its night side. Indeed, even when Venus is brightest in the Earth's sky, we are actually seeing only a narrow crescent. For a Mercurian observer, on the other hand, Venus is closest when it is in opposition to the Sun and is showing ...
The EnVision Venus explorer will study that planet in unprecedented detail, from inner core to the top of its atmosphere, to help astronomers understand why the hot, toxic world didn’t turn out ...
A NASA spacecraft has captured never-before-seen images of Venus, providing stunning views of the hellishly hot surface of the second rock from the sun. Dark side of Venus revealed in new NASA ...
Jupiter and Neptune have ratios of power emitted to solar power received of 2.5 and 2.7, respectively. [27] Close correlation between the effective temperature and equilibrium temperature of Uranus can be taken as evidence that processes producing an internal flux are negligible on Uranus compared to the other giant planets.

This month’s stargazing agenda brims with planet sightings. We have planet pairings, moon-planet hangouts, and a special treat to end the month: several evenings with all seven of our space ...
The dense greenhouse atmosphere on Venus keeps its surface hot enough to melt lead throughout the night. [33] [34] Its planetary wind system, driven by solar heat, reverses direction from day to night. Venus's winds flow from the equator to the poles on the day side and from the poles to the equator on the night side.
