This might sound crazy people, but I thought of a theory that Mercury was once a moon of Venus. Here's how; so our moon moves away from us I don't even know how many inches or centimeters ever year, that happens with every single moons of planets. Haven't you think that Mercury was once Venus' moon pulled apart from Venus' gravity due to that natural process of movement? I mean think about it. Our moon moves away from us some centimeters or inches each year. Same with Mercury, it might have been pulled away from Venus, making Venus what it is right now. I think this is very likely to be true. Mercury even has the same composition as our moon does, but it also has iron due to the fact that it is so close to the sun that it just creates some other material on it's surface and because the Sun's radiation creating stuff on it.

Another theory, Mercury could have been a remnant of a gas planet. If you look at other gas planets such as Saturn or Jupiter, it's core is made of iron and rock. Same goes with Mercury, but Mercury's surface is stripping away due to the heat it gets from the sun. And because of that, Mercury's atmosphere stripped away due to the amount of heat because of how close Mercury is to the sun.

Anyone want to take a theory of this and add on or give feedback? This both are extremely likely to have had happen.

Our moon drifts away because of tidal forces of our oceans. Venus' oceans of... whatever liquid that can be a liquid at 700 degrees F isn't enough to affect any orbiting object

no they have completely different rock compositions and other features
so it couldn't have come from venus

venus doesnt have the gravity to pull in a moon so...

@why
our moon will deorbit because it isn't in a perfectly circular orbit
on one side it is pulled on a little harder by Earth so it speeds up a small bit
eventually this will be enough speed to let the moon escape
our oceans do nothing to the moon

No I mean it's possible that Venus was like Earth long ago. Take a look at the moon Titan. That's an example of early Earth. So it might be possible. You never know you know. Please read the whole thread..

not every moon moves away from the planet, some move inwards

@Lieutenant

as quoted from a BBC article:


The Moon is kept in orbit by the gravitational force that the Earth exerts on it, but the Moon also exerts a gravitational force on our planet and this causes the movement of the Earth's oceans to form a tidal bulge.

Due to the rotation of the Earth, this tidal bulge actually sits slightly ahead of the Moon. Some of the energy of the spinning Earth gets transferred to the tidal bulge via friction.

This drives the bulge forward, keeping it ahead of the Moon. The tidal bulge feeds a small amount of energy into the Moon, pushing it into a higher orbit like the faster, outside lanes of a test track.

This phenomenon is similar to the experience one feels on a children's roundabout. The faster the roundabout spins the stronger the feeling of being slung outwards.

As the Earth's rotation slows down, our whole planet may start to slowly wobble and this will have a devastating effect on our seasons”

Dr Maggie Aderin-Pocock
But the energy gained as the Moon is pushed higher is balanced by a reduction in the energy of its motion - so an acceleration provided by the Earth's tides is actually slowing the Moon down.

@65

I'm pretty sure Venus is too close to the sun to have liquid water

You know the sun grows too right? In about some billion years the sun will be a red giant and Titan will be what Earth looks like now.

that couldn't be true because the water "bulge" could not release enough energy to travel through air, and then the vacuum in space and affect the moon

thats the internet for you m90

If Mercury couldn't be a moon, then it's very likely it could have been a former gas planet that stripped it's atmosphere away due to it being so close to the sun. If you watch space videos a lot like I do, you would see some videos saying that some planets so close to their sun they're evaporating away. That might have been the case to Mercury. It's even evaporating right now, the rocks are dissapearing from Mercury due to the heat. If you look at Io, Jupiter's moon, it's like a cheese... In other words, it's like Mercury, but inside out. Jupiter and Saturn is like a solar system you know.

@guy that mentioned the ocean

You're confused. The moon pulls on our oceans which results in the different tides throughout the day.

I have just did and I just realised there are many topics like this... Yet none have been approved but have been theorised as highly possible on both sides. I also found out that a planet beyond Sedna may exist..
