why is venus rotation so slow

C) Its atmosphere is much denser than the Earth's. They say these structures may be atmosphe There are several theories as to why Venus has a slow retrograde rotation, according to Why Venus Spins the Wrong Way (Franzen, 2001), states that a theory of this phenomenon states that. Its winds reach velocities higher than four hundred kilometers per hour, seventy times faster than the rotation of the planet. Since the energy that produces the tides comes from the Earth's rotation, it follows that whenever energy is lost in the tides, the Earth's rotation will slow down.Friction related to the tides. A) Its slow rotation. Venus spins on its axis from east to west, while Uranus is tilted so far over, it's virtually spinning on its side. So does Pluto.Uranus after taking a blow that tipped it >> >> about 100 degrees did not slow its rotation. The current opinion is that Mercury's rotation is slow because of tidal braking by the Sun. The rotation rate of Venus is difficult to measure because of the planet’s constant cloud cover.

Does the Venusian atmosphere's “super rotation” actually rotate? Why is that? Why would Sun-synchronous orbits be impossible around perfectly spherical bodies? 3 comments . And there are hypotheses that Venus slow and reversed rotation is caused by coupling to the Sun, another factor to consider here. With a toxic blanket of carbon dioxide, the surface pressure on Venus is 90 times what we experience on Earth at sea level. But this puzzle is not yet solved." The actual period of rotation of Venus is 243 days. According to the new data, Venus is rotating 6.5 minutes slower than it was 16 years ago, a result that's been found to correlate with long-term radar observations taken from Earth. Displaying vertex coordinates of a polygon or line without creating a new layer. Could the Galilean moons tidally lock Jupiter? With the new data, there is still no definitive answers, but very interesting theories. Which one offers evidence of a global repaving about a billion years ago? It is suggested that the slow rotations of Mercury and Venus may be connected with the absence of natural satellites around them. Right now, it has almost two rotations per orbit, just a little less, and the day is still getting longer and longer. atmospheric dynamics. Re: Why Does Venus Rotate so Slow? Exactly why is a mystery. The present rotation period of Venus represents an equilibrium state between gravitational tidal locking by the Sun that tends to slow the rotation rate, and an atmospheric tide created by the solar heating of Venus's thick atmosphere. That's not to say that there's no variation. If it spin as fast as Earth 24h for full rotation would it be more Earth like? Is there an easy formula for multiple saving throws? Be like SMART BANANA: https://goo.gl/JTfP6L Oh space, you wily minx. The mechanism behind this, according to the theory, is that. Instead, he said, further study is needed to discern the cause—or causes—of Venus' slight reduction in speed. Venus' spin varies because of atmospheric waves over the planet's mountains, according to a new study. Stack Exchange network consists of 176 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. How can I organize books of many sizes for usability? The rotation of the planet Venus is slowing down, according to recent data gathered by the European Space Agency's Venus Express satellite. ". (Also see "Early Venus Had Oceans, May Have Been Habitable."). What is a "constant time" work around when dealing with the point at infinity for prime curves? Ultimately, he added, it's important to know exactly how fast the planet is spinning, since any possible future missions to explore Venus will need precise information to chose their landing sites. Why do Clang and MSVC not like a member typedef declaration with a redundant set of parentheses? Why is the rotation rate of Venus so slow? The solar tide is slowing the rotation of Venus down. The motion of the atmosphere on Earth, for example, has been observed to affect … Source(s): wikipedia. ​ Rings Anonymous says: February 10, 2012 at 11:46 PM Venus is so like Earth OK what is the best the imperial thinkers can do on the reason it rotates ar a walk? 3 0. wilde_space. Weirder yet, the direction of its rotation is opposite to most planet's, including ours. "But we have checked every possible error we could think of.". Is Venus so inhospitable because of the slow rotation speed around its axis? To add to the mystery, the article Venus Spinning Slower Than Thought—Scientists Stumped (Major, 2012) suggest that the rotation is slowing down even further, with. source, "It is difficult to find a mechanism that will cause the average Changing a mathematical field once one has a tenure. A) Venus has relatively few impact craters and these craters are distributed fairly even over the entire planet. Details Published: 10 February 2012 Hits: 1115 Source: Universe Today ; New measurements from [ESA’s Venus Express]spacecraft shows that Venus’ rotation rate is about 6.5 minutes slower than previous measurements taken 16 years ago by the Magellan spacecraft. The material of the planetoids would melt. One possible cause for the slowed spin is friction caused by Venus' thick atmosphere and high-speed winds. Why can't we use the same tank to hold fuel for both the RCS Thrusters and the Main engine for a deep-space mission? When the planetoids merge their surfaces are moving on opposite directions. For one, Venus has an atmosphere that is incredibly dense (92 times that of Earth, in fact) and reaches temperatures that are hot enough to melt lead. Technically yes, but Uranus is more accurately thought of as rotating on its side which presents its own unique features.
