Moon Question. Please Give a real answer.?

Question

Is it possible for the moon to form as a twin planet and still be the moon. Imagine the moon being just like earth and being able to go between both.

Is that possible: Theortically?

So It's not possible for the moon to be like the Earth and be a moon?

What would happen if the moon was like the earth?

Why would we be able to travel between both?

Answer 1

i think that our moon was made in a diffrent manner than earth was. I am not sure the details of either one, but i know that they are diffrent materials etc so life on the moon is impossible.

Answer 2

I don't think it would be possible because the mass of the second planet would be too big and thus the gravitational pull would be too large also. I think they would collide. Also, the moon would have to circle one of them by being solely in their gravitational field likewise. Actually, they now think that a large planet did hit the earth toward the top part. Not a direct hit, but a passing glance. It tilted the earth and broke off major amounts of crust and this rock, powder and gas coalesced as it circled the earth like a ring on Saturn. Ultimately, it formed the moon as we know it. But, the moon at one time was real close to the earth and would like like a next door planet! The moon gets farther and farther away every year by 3.8 centimeters or 1 and a half inches. The moon has no iron center as earth does-just crust material plus meteorite impact minerals. Thus, they had different origins. Our iron center creates a magnetic field around the earth so we can have an atmosphere. The magnetic field blocks ultraviolet rays from the sun and prevents the destruction of our atmosphere. And since we have an atmosphere, there is sound and thus we needed ears!

Answer 3

If the moon had the same mass as the Earth then they would rotate about the point equidistant between them. It would then be impossible to call it a moon, instead it would be a binary planetary system.

We simply call the smaller body the moon and the larger one the planet.

Our Earth / Moon system is slightly binary, we orbit the moon a bit as it orbits us. The maths is difficult but you can calculate the center of the orbiting pair is just beneath the earths surface, not the center of the earth as shown in animations and books. (This is why we have two tides a day and not just one. There is one on the side of the earth as the moon due to gravity from the moon pulling the water, and one on the back of the earth due to centripetal acceleration as we swing around the moon!)

Oh, and one final point in answering if you could go between the binary planets? You'd still need to gain enough speed (escape velocity) to get away from your planets gravity and halfway to the other planet. It's not like you can jump up and float there !

Answer 4

It would not be possible for the moon to become a planet-like binary partner with earth without losing the characteristics that identify it as the moon. You are proposing a logically empty concept.

It is possible to "go between both" as things are now, however. It's just kind of pointless.

Answer 5

If both are the nearly same size then it's a binary planet...neither one is a "moon." Theoretically possible, but highly unlikely. But, hey, it's a big universe.

Answer 6

Hi. Yes, there would be enough mass in both halves to hold thee moonlets together. They could orbit on opposite sides of Earth at the Lagrange points so you could fly between them.

Answer 7

there are planets with two or more moons. since this planet has only one moon, I guess we are stuck with it. In the future, if you want a real answer, please give a real question.

Answer 8

theortically, probably, but i think it wouldnt be considered a planet because its to small

Answer 9

I'm not sure what you mean. you might get something useful out of these links:

Answer 10

Of course but Who is going to do it?And why?
