Can one planet share its orbit with another? Here is the Answer

Today we’ll see the continuation of the potential objects in the universe that could exist. We’ve previously done a video about it and many of you asked me to do a continuation of it. So, this is the second part. Imagine that Jupiter loses all of its gas.

What are you left with?

A rocky or metallic core, of course.
Very similar to an Earth-like or rocky planet.

These kinds of planets, which result from a gaseous giant that completely loses its atmosphere are called ‘chthonic planets’. from the greek ‘χΦονιος’. Which means ‘terrestrial’.

But how can this happen?

How can such a big planet lose all of its gas?

Indigestion?

No. The loss of atmosphere by a gaseous giant can be caused by its proximity to its star if it’s too close to it.HD209458b, also known as ‘Osiris’, is an example of a planet that is considerably losing its atmosphere due to evaporation, and even though it’s not yet a chthonic plalnetIt’s foreseen to become one in a nearby future. However, that’s not the only possible case.

In 2011, the space telescope Kepler discovered two planets that orbit around the star KIC05807616 at a distance 50 times greater than Mercury’s orbit.

Presumably, these planets could have been gaseous giants that were reduced to their iron cores once their star became a giant red. Some scientists suggest that Mercury -yes, the one in our solar system is a body of this kind because of its high density and its metals-rich core. Perhaps Mercury once was gaseous.

Now let’s pass to another kind of hypothetical planets. The ‘carbon planets’.These kind planets would be rocky, just like ours. But instead of being mainly composed of silicon it’d be carbon. It’s predicted that these carbon planets would have a similar diameter to those made out of silicon and water were seen in the previous video, which makes them difficult to spot. They can also have similar geological characteristics to Earth but with different compositions. For example, the rivers there could be petroleum. If the temperature is low enough, below 350 kelvin then gases could be synthesized into hydrocarbons such as methane and butane which would fall as rain.

Petroleum rivers and methane rain. The same way, some carbon planets could have solid diamond mantles or cores this may sound incredible, but remember that diamonds are carbon compounds that have been formed under extreme pressures and temperatures in Earth’s interior. Then it’s not unreasonable to think that a planet could have diamonds beneath its surface.

You could open a jewelry store. But remember, ‘carbon’, not ‘charcoal’Diamonds do not proceed from charcoal, that I have already explained it in another content of geological myths.

In 2011, NASA canceled a mission called ‘TPF’such mission aimed to be a much greater observatory than the Hubble space telescope, which had been capable of detecting such planets.

Carbon planets’ spectrum would lack water but it would show us the presence of carbon-based substances such as carbon monoxide. For now, we haven’t found any yet but scientists trust that within the next decades with more sophisticated and better telescopes, we will.

Have you ever heard of the ‘Trojans’?

Well, Trojans don’t only exist in books, movies, and your computer…They’re in space too Trojan objects orbit 60° either past LaGrange’s point L4 or behind the point L5 of a much more massive object, both orbiting around an even more massive central object. But what are Lagrange’s points?

We’ve seen that before, but a brief reminder does no harm. They’re positions in space, where the combined gravitational interaction of two large bodies-for example, the Sun and Earth can sustain a third much smaller body such as an asteroid in a stable orbit with one of the larger bodies.

In the solar system’s orbits, there are considered five Lagrange’s points. For some time it’s been confirmed the existence of Trojan asteroids, these are asteroids that share an orbit with a planet around Lagrange’s points previously mentioned.

The Trojan asteroids are distributed around these points. Jupiter, for example, has an astonishing amount of Trojan asteroids. Can you guess how many?

4800 discovered so far.

Earth also has a Trojan asteroid that accompanies it in its trip around the sun. It’s around 300 meters (984.252 ft) in diameter and has been baptized with the name of2010 TK7.

Anyone would have named it ‘Little Troy’ or ‘Little Earth’. Just saying. However, there are not only Trojan asteroids, there can also be Trojan minor planets.

To those who want to learn a better definition of ‘minor planets’, or ‘planetoids’, or ‘dwarf planets’, I’ve also got another video about such astronomical objects right here in the video suggestions. Besides, there can also be Trojan moons Trojan moon is one which orbits nearby the Trojan point of another bigger moon. All of the known Trojan moons known are part of Saturn’s system.

However, what is yet to be discovered but that could exist, are the so-called ‘Trojan planets’.

These planets would share their orbit with others. Some years ago it was thought that a pair of co-orbital exoplanets were orbiting the star Kepler-223.

Initially, it was thought that this system had two planets orbiting the star about the same orbital distance every 9.8 days, with one of them permanently locked 60° behind the other in one of Lagrange’s points.

Nevertheless, this data was discarded later on That is, so far not a single Trojan planet has been discovered yet, and that’s why it’s still considered as hypothetical.

Let’s move on now from planets to stars.

Let’s see the quark stars.

Stars that are also called ‘strange stars’.These stars would be made out of a broth of quarks, matter’s main components. astronomers believe that these stars form after a mid-sized star-around 1.48 times the size of our sun runs out of fuel and starts its final collapse stage in its life cycle. As it collapses, it squishes protons and electrons together, forming neutrons. However, scientists believe that if the star is heavy enough, and continues to collapse after this stage, such created neutrons could discompose into their quark components under such immense pressure, creating so an incredibly dense kind of matter.

In a study published some years ago, it’s explained that such stars could be covered in a thin nuclear crust mainly consisting of heavy ions submerged in an electron-based gas. Well, that’s it for this video about hypothetical objects in the universe that could exist. Did you like this content?
