source, "It is difficult to find a mechanism that will cause the average "Venus is a mind bender for specialists in atmospheric dynamics. Venus rotates plenty slower than earth does around its very own axis. Its winds reach velocities higher than four hundred kilometers per hour, seventy times faster than the rotation of the planet. A) Venus has relatively few impact craters and these craters are distributed fairly even over the entire planet. The 584-day average interval between successive close approaches to the Earth is almost exactly equal to 5 Venusian solar days, but the hypothesis of a spin–orbit resonance with Earth has been discounted. In other words, it spins in the same direction it always has, just upside down, so that looking at it from other planets makes the spin seem backward. The material of the planetoids would melt. But this puzzle is not yet solved." Could the Galilean moons tidally lock Jupiter? Why is the rotation rate of Venus so slow? Would it be possible to “ride the wave” on Venus? The mechanism behind this, according to the theory, is that. Venus rotates so slowly because of its retrograde motion, an unknown cataclysm has been able not only to stop the motion of rotation due to the angular moment that Venus possessed during its origin, but even to invert it!

It might eventually slow down to one Venusian day per Venusian year. Venus has an extremely slow rotation rate, to the point that it actually rotates slower than it revolves around the sun. Thick clouds swirl on Venus in a 2007 picture taken from orbit. It only takes a minute to sign up. Venus' thick atmosphere slows its rotation Bow-shaped structures in Venus' atmosphere could be slowing the plant's spin by a few minutes per day, making it harder to pin down the exact length of a Venusian day, according to international researchers. But this puzzle is not yet solved. Venus rotates very slowly, taking 243 Earth days to rotate once around its axis. 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. Anonymous says: February 10, 2012 at 11:46 PM Technically yes, but Uranus is more accurately thought of as rotating on its side which presents its own unique features. In the early 1990s scientists with NASA's Magellan mission calculated that a single rotation of Venus takes 243.015 Earth days, based on the speed of surface features passing beneath the orbiting spacecraft. And there are hypotheses that Venus slow and reversed rotation is caused by coupling to the Sun, another factor to consider here. The current opinion is that Mercury's rotation is slow because of tidal braking by the Sun. Which of the following contributes to Venus being so hot? 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? All rights reserved. Not only Venus rotates very slowly, it also rotates the wrong way! share. I heard that one of the main reasons that Venus is so inhospitable is because of its slow spin around the axis is there some truth to it? Give Venus a few more million years, and it's rotation will slow down to the point where it matches it's orbit. Why is that? The initial counterclockwise rotations of the planetoid would be cancelled. Does the Venusian atmosphere's “super rotation” actually rotate? Venus Spinning Slower Than Thought—Scientists Stumped, Tips to stay focused and finish your hobby project, Podcast 292: Goodbye to Flash, we’ll see you in Rust, MAINTENANCE WARNING: Possible downtime early morning Dec 2, 4, and 9 UTC…. Physicists adding 3 decimals to the fine structure constant is a big accomplishment. The atmosphere also rotates much faster. Venus is so like Earth OK what is the best the Space. between the two objects averaged out to the current rotational speed in the solar cycle or in long-term weather patterns that modify the And there's two, nay three more odd things about it's rotation on its own axis, namely: Venus is indeed an oddball. Still, "it is difficult to find a mechanism that will cause the average rotation rate to change this much in only 16 years," Venus Express project scientist Håkan Svedhem told National Geographic News. 3 comments . Grammatical structure of "Obsidibus imperatis centum hos Haeduis custodiendos tradit", Differences in meaning: "earlier in July" and "in early July". Second order transfer function with second order numerator? 2020 National Geographic Partners, LLC. Venus' spin varies because of atmospheric waves over the planet's mountains, according to a new study. All the following statements about Venus are true. A) Its slow rotation. Planet lovers take note: Venus is spinning even slower than astronomers thought, according to new data from a European space probe. In other words, its day is longer than its year. what does "scrap" mean in "“father had taught them to do: drive semis, weld, scrap.” book “Educated” by Tara Westover, Is copying a lot of files bad for the cpu or computer in any way. Instead, he said, further study is needed to discern the cause—or causes—of Venus' slight reduction in speed. In other words, it spins in the same direction it always has, just upside down, so that … How does Venus' thick atmosphere survive against the solar wind? source, The rotation period of Venus may represent an equilibrium state between tidal locking to the Sun's gravitation, which tends to slow rotation, and an atmospheric tide created by solar heating of the thick Venusian atmosphere. The solar tide is slowing the rotation of Venus down. 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. But scientists now mapping Venus's surface with the European Space Agency's Venus Express orbiter were surprised to find the same features up to 12.4 miles (20 kilometers) from where they were expected to be, based on the previous measurements. 2 possible mechanisms for this slow down are: an exchange of angular momentum with Earth. Venus initially spun in the same direction as most other planets and, in a way, still does: it simply flipped its axis 180 degrees at some point. TreBert PS I have my own ideas too. It actually spins roughly in 58 days and 15 hours, not 176 days. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Venus Rotation May be Slowing. 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. A) Its atmosphere is made chiefly of carbon dioxide. Is the retrograde (clockwise) rotation rate of Venus speeding up or slowing down?
