what the reason that venus rotate clock wise and how many of u think there was life on mars in the past ?

The rotation of Venus is believed to have been caused by a huge planetary impact that occurred very very early in the formation of the planet.  A similar event is thought to have happened to Earth and it lead the the formation of the Moon.  As for life previously existing on Mars, I think it is possible.  However it was probably only microscopic bacteria-like organisms.  We will never now until humans do some on-site digging in the Martian crust.

It's completely beyond our current science and technology to replicate the environment of Mars with such precision that we could be confident that we'd have the exact same (or even similar) conditions for life as exist on Mars.\n\nIn addition, how would we replicate Mars' environment when we know so little about it?  You'd need to send thousands of probes to Mars to get enough information to even *begin* such an experiment ... and by the time you'd finish that, you could've already run a full set of experiments on Mars testing directly for the past or present existence of native life forms.\n\nA planet's biosphere is an incredibly complicated thing.  It's something that scientists seem to only now be learning about our own biosphere, unfortunately a bit too late.

The earth rotates on its axis (spins) the same way as the sun does on its axis, since the planets all formed out of the proto-solar disc when the sun was forming.  All of the planets spin the same way, EXCEPT for Venus, which rotates (very slowly, once every 243 days) in the opposite direction.  Some planetary scientists consider this evidence that Venus at one time collided with another large body early in its lifetime, which caused the retrograde rotation.

According to current accepted beliefs, there is no people in Mars, although there has been fossils of single celled organism.\n\nWe should stick to this, until we found any further information about living things in Mars.

Venus rotates clockwise (as seen from Earth) in retrogate rotation as well as Uranus and Pluto. However, it is the only terrestrial planet that rotates in the opposite direction. The theory is that a large asteroid impacted it and that reversed its motion. As a result, it orbits the Sun faster than it rotates, creating a hostle environment with hot surface temperature, making it the hottest planet in the solar system, (hotter than Mercury, although it is closer to the Sun).

First "time" is relative.  \n\nAs you should know time as we know it is based on the rotation of the Earth, 24 hrs to make one revolution and 365.4 days to go around the Sun.  \n\nMaking the assumption that time is based on the revolutions of the planet you hypothetically happen to be on, time would be different on each planet because the day/night revolutions and the time to go around the Sun are different than on Earth.\n\nIf you were on Mars the Martian year is much longer that the Earth year, as it the day.  If you took you watch to mars and went by it, it would not make much sense on Mars because it is set to Earth time.  \n\nIt  sort of be like if you traveled to Sidney Australia but you were still on New York time and you tried to live like you were still in NY.  It wouldn't work very well.

Of course there is.  You would have to be crazy to think we're the only ones in the universe and the parallel universes, and so on.  They found rust on Mars, which means there was water - therefore leading to the conclusion of life on Mars.  If there was life on Mars, you better believe there's some kind of lifeform billions and trillions of light years away.  No life was discovered yet because we haven't built rockets that are capable of taking us to the destinations of where we haven't discovered yet.

Its earth and venus...the reason behind it is due to their some what similar size, mass of planet, rotation and revolution time and gases in some cases. hope so u satisfied with my answer.

Exactly. Your an optimist. Keep it up! Its optimism that makes the earth rotate or else it would have stopped.\n\nForget the past , think of the future. We always take steps forward , never backward. So why do we think of the past. Yesterday is History. Right said. Tommorrow is a mystery, even better. \n\nLive today to the fullest.

Well, that is one hypothesis, which is "conjecture", which is just to say it's a "great big guess".  No astronomical explanation has thus far been a satisfactory explanation, because the hypotheses fail to explain "why" comets orbit the Sun clockwise, while everything in our Solar System rotates counter-clockwise along with the counter-clockwise rotation of the Sun.\n\nMy analysis has determined that our Solar System and the Sirius Binary System are interlocked in an electromagnetic deadly dance of death in which the two systems cyclically and recurrently interpenetrate through each other every 12,000-year period.  Hence, our Solar System is on a collision course with the Sirian System.  This transversion is an extinction level event that I have identified as the Sirian-Solar Reconvergence.  The Sirian Binary rotates clockwise, thus comets are dislodged debris from the Sirian System captured within our Solar System from each Reconvergent event in which the comets retain their original clockwise rotation due to their immense velocity that cannot be overcome by the rotational influence of our counter-clockwise system. \n\nThe Sirian-Solar Reconvergence also explains all the crater impacting that has scared all the solid-body planets.  As the cosmocataclysm ensues all the debris from the various debris belts in both systems dislodge and rains down mass celestial bombardment on every object in both systems, particularly when the Reconvergence reaches its critical vertex of transversion.\n\nAdditionally, the Sirian Solar Reconvergence would completely explain why the planet Venus spins clockwise and backwards (opposite to the spin of the other planets) while revolving around the Sun counter-clockwise, thus creating the unusual phenomenon of one day being one year, because it completes one revolution in one year.  Clearly this is an indication that Venus was originally a planet torn out of its clockwise orbit in the clockwise Sirian System during one of the Reconvergence, and was captured by our Sun.\n\nThe reason why the two systems are locked in this process is because they were formerly unified as one solar system; our system was originally the Osirian Trinary Stellar System.  Sirius B is our original paternal star, Sirius A was the outer star that orbited the body of the system, our Sun (Sol) was technically Sirius C, originally a binary companion with Sirius B at the core of our former Trinary System, and there were originally a total of eleven planets.  The split occurred because Sirius B after depleting its helium as a Red Giant exploded into a Nebula Discontinuity Event, creating the Local Compression Bubble and precipitating the celestial dynamics that tore the system in half.  The two halves journey off to their greatest distance, and then invert and return to the path around the galactic center that they were originally blown apart from, being the recyclic event of the Sirian-Solar Reconvergence.  This cosmocataclysm wipes all human civilization off the face of the Earth and catapults Mankind back to a State of Neobarbarism to begin the slow and incremental process of re-civilization all over again.  It is also responsible for suddenly laying down the Geological Column and entombing the charred bones of beasts and men into fossilization within the stratification, because the event is so violent, catapulting the Earth out of its orbit and thrusting the oceanic waters out of their basins, overrunning the continents.\n\nAs our Solar System and the Sirian System near ever closer, signs of the next Sirian-Solar Reconvergence are mounting, being the environmental deterioration of the terrestrial environment, increased volcanism on the oceanic floors that is heating up the seas and affecting the climatic temperatures, the melting of Earth’s and Mars’s polar ice caps, new red spot storms on Jupiter, the addition of a third belt to the Van Allen Radiation Belts that surround the Earth, the vio

For years it was thought that in the case of Venus that the Earth was the culprit. It is a curious fact that as Venus rotates three times on its axis in 729.27 days, the Earth goes twice around the Sun ( 728.50 days) This has suggested to many dynamicists that Earth and Venus are locked into a 3:2 tidal resonance. There are many bodies in the solar system that seem to be locked into various kinds of spin-orbit resonances, especially families of asteroids with the planet Jupiter. Mercury also seems to be gravitationally locked into some kind of resonance with the Sun since its day (58.646 days) and its year ( 87.969 days) are also in the proportion of 3:2. \n\nwhat happened in essence is that venus spins once a year which is about zero rotation in the normal planetary sense.  evidently the way the solar system formed it just sucked the spin out of venus.  that probably accounts for why it's a greenhouse.

I think we would be very naive to believe we are the only life form in the universe.As vast and diverse as it is,I believe there has to be a reason for the formation of these planets to sustain life.That said,who knows when the life was present on these planets?And who knows what life forms are out there as we speak?Perhaps Mars and Pluto had life trillions of years ago but there are no remnants now for us to find.It's a fascinating topic.If you think about the possibilities,it's incredible.

Mars is the Roman god of war and Venus is the Roman god of love. Jules, Australia.

Cuz the planet has a 23 hour 59 minute rotation.\n\nWe needed a way to keep track of things, and somebody made up this system.

you almost answered your own question..\ntake out the lost part and the decendants part and you have the ingredients to what a lot of us believe...even mars has pyramids and a face structure( look up "the face of mars").\nplanet exploration is something that would have happened regularly if our universe is infinite and you believe in other life forms....we are from afar and have today, lost our way :)

Earth's graceful 24-hour rotation rate is one of the traits that makes our planet so friendly to life, allowing most parts of Earth to stay a nice, comfortable temperature as they are bathed in sunlight during the day and darkness at night. \nEach planet in the solar system has its own unique rotation rate. Tiny Mercury, sizzling closest to the Sun, takes 59 Earth days to turn around just once. Venus, the second planet, rotates once every 243 Earth days. What's more, Venus rotates backwards from the direction of its orbit around the Sun, as do Uranus and tiny Pluto. Uranus even lies down on the job, rolling around with its axis of rotation pointed nearly toward the Sun.\n\nWhy do Earth and the other planets rotate at all? It will help to understand how our solar system formed. Almost five billion years ago, our solar system had its beginnings as a vast cloud of dust and gas. The cloud began to collapse, flattening into a giant disk that rotated faster and faster, just as an ice skater spins faster as she brings her arms in. The Sun formed at the center, and the swirling gas and dust in the rest of the spinning disk clumped together to produce the planets, moons, asteroids, and comets. The reason so many objects orbit the Sun in nearly the same plane (called the ecliptic) and in the same direction is that they all formed from this same disk.\n\nYou can visit this nasa site which has audeo narration and animation on earth rotation.\nhttp://spaceplace.nasa.gov/en/kids/phonedrmarc/2003_march.shtml
