if a large object hitting earth created our moon--then{WHY]couldn't that object be the planet Venus--???

Answer 1

You got it wrong. To start with, if you enter the paths of both Earth and Venus on a supercomputer and calculate back in time if something like you said could have happen, you have less than 1% chances. Venus is on a very circular orbit so is unlikely it happened like that.

But besides that fact, you need to research more about the theories of Moon formation.

Our latest theory explains that the Moon and Earth were actually formed from the collision of two planets. The original Earth (usually called Proto-Earth) was about 90% the size of our current Earth. The second planet was not bigger than Mars.

The collision wasn’t like on the movies. It was in fact slow and they didn’t collide directly, but just “touched” on a off angle. The result was great heat and destruction of almost both planets. From far away, it would look like a slow motion movie as everything happened in a period of days.

The latest computer results show that in fact, after the first crash, both planets got “sucked” towards each other due to gravity, ending on a second crash that this time was a direct impact pretty much. At that point, both planets broke apart, and gravity little by little put them back together into a one planet which is our Earth.

But due to centrifugal forces, some mass escaped the main gravity attraction and kept a semi steady orbit around the new Earth, condensing by gravity once again, and becoming our Moon.

Back in those days, the Moon was much closer to Earth than now, but as we now know, we are “loosing” the Moon as its orbit is not perfect and little by little it keeps going farther away making our day longer and forcing Earth into a more unstable spin (the Moon help Earth stay balanced in orbit so the equator always points towards the Sun).

All this happened billion of years ago. Recent studies suggest that it must have happened right after the final formation of the inner planets. It also raises questions about the theory and calls for a re-evaluation.

But at the end, is just a theory and is the most accepted as it gets to explain almost everything about the Moon, the orbit, the composition, etc, etc.

Any interaction with other planets has been impossible to be proven as no computer has been able to predict the current orbits from other crashes like the one you suggest. Still it could be a possibility as we don’t have all the clues with us. Maybe Earth and Venus were one planet before and a colossal crash split the planets, and then other crashes made Venus enter into it’s orbit. We can’t tell as there is no signs of it anywhere, but the remains of such an event could have been catapulted towards the Sun or out of the Solar System, making for us impossible to know.

For now we don’t know what really happened, and probably we won’t be sure unless we discover time travel so we can go back in time and witness the envents.

Answer 2

Mostly because Venus is still there. Also, if Venus had been in our vicinity at any time in the past (even billions of years ago), then either we or Venus would still have a very eccentric orbit (a very squished ellipse instead of the almost-perfect circles that both Earth and Venus follow).

Finally, the rotation of Venus can be explained by solar tidal effects if Venus has been on its present orbit since its formation at the start of the solar system.

There is also the annoying question of mass: Venus is too big, Earth -- and probably Venus as well -- would have been completely shattered by the collision.

Answer 3

If Venus hit earth then the two planets would have entrapped each other in their prospective gravitational fields. This means that after impact the two bodies would be pulled toward one another resulting in one main body in which the remainder would orbit the other.

There is just no way that Venus could have hit earth left part of it here then continued on to where it is and start on a near perfect orbit around the sun.

The body that hit the earth to form the Moon is still here as part of the earth and most of the moon.

Answer 4

The large object that presumably hit the Earth to create the Moon was a Mars-sized object. It no longer exists as a separate object because it is smashed into the Earth.

Answer 5

It is impossible to know, just from walking into a home, whether it is the home that is haunted or an object in the home. The team on "Haunted Collector" review cases and do research and choose their cases based claims of items with strange histories or activity centered around items. And even they get it wrong sometimes and find the house is haunted rather than an item in it. Now, if you have activity that started immediately following the acquisition of an object, then it is possible that object is haunted. Get rid of the object. If the activity stopped, it was the object. If not, then it's the house.

Answer 6

Venus is about the same size as Earth is now, which means the proto-Earth was probably less massive than Venus. The impact of the Mars-size object added about 15% more to the Earth as it is now, in addition to the debris which became the moon.

Answer 7

Venus is too large for the calculated mass of the object and, besides, Venus is still there.

Answer 8

Let me guess...been reading Velikovsky?

Venus has an almost circular orbit. It is EXTREMELY unlikely that it EVER passed near the Earth. In addition, the impactor that is theorized to have created our moon would have been vaporized.

To even consider this as a possibility displays a PROFOUND misunderstanding of orbital mechanics. Period.

Answer 9

If Venus had collided with the Earth, it is very unlikely that Venus would be in its current near-circular orbit.

Answer 10

Your entire arguement is quite impossible .........
