All planets have no stars
When you think of a planet, you probably think of one of the planets in our own solar system like Earth, Jupiter or Mars.

Earth’s “Evil Twin” hides many mysteries under its opaque environment.
Most of the exoplanets we discovered are like those in our solar system. They revolve around their original stars like tomorrow.
However, not all planets are present in such systematic systems. Some planets are floating through the galaxy alone, especially not bound to any star. These virgins are called “evil planets” or sometimes “free-flotting planet”.
They are not easy to study, as they do not revolve around any star, and it cannot be seen firmly or repeatedly. Scientists need to be basically lucky and find one at all to find out in front of a random star as an evil planet.
What are the crook planets?
Wicked planets, a lot like you find in solar systems, come in every shape.
Some are spacious and gaseous, a lot of Jupiter (and sometimes large), while others are more like snow veterans Neptune or Uranus, which are small.

These 5 Neptune facts blown my mind
There is a giant of esoteric ice compared to the eye meeting.
And some of them are like our own planet- small and rocky.
The major feature that combines all of them together is temperature.
Because they are not warm by an original star, the surface of the evil planets is all quite cold. In which summer they are.
Some of that internal heat is mechanical. For example, when you benches a piece of plastic repeatedly, mechanical forces at work during the formation of a planet produce heat, which is considered sufficient to completely melt the surface of rocky planets. The heat gradually fades as the age of the planet.
Another source of heat is radioactive decay. Heavy elements (including radioactive) got stuck in the centers of the planets. As those radioactive elements undergo decay, the core is continuously heated.
Collectively, those two sources could keep extreme toast inside a planet for a very long time. For example, take the earth. The Earth is approximately 4.5 billion years old, and it is believed that the origin of the Earth is somewhere between 5,000 and 6,000 ° C – about the same temperature as the surface of the Sun. The rhythmic gravitational bridge of the moon also adds slightly.
In billions of years, their original winds will become completely frozen in their original winds, as heat from their formation and radioactive materials.
How do wicked planets are formed?
Some evil planets make “normally”, such as in our solar system. In the form of dust and gas soup (properly called protoplanetary disc) revolves around a newly created star, the particles slowly collide with each other and start climbing up. In millions of years, some of these clumps get large, which start vacuuming everything in their classrooms, as we know that make planets.
However, these are not a quiet time in a solar system. They are marked by rapid changes and instability. As many planets are formed, the instability in the system occurs in the planets that migrate in different classes. Sometimes, if a planet is particularly inauspicious, it is completely removed from the solar system, resulting in an evil planet. Another star passing by (or black hole or neutron star) can also destabilize an existing solar system, resulting in a planet out.

We know more about them as much as you can think.
Alternatively, scientists believe that perhaps it is possible for evil planets to get out of the clouds of floating materials in space, such as the stars themselves. However, there is some debate about how big such planets will be.
Either way, once a planet starts moving through the galaxy on its own, it will probably be forever.
Can life be present on an evil planet?
Perhaps, but it will probably be very limited that you can find on planets orbiting planets.
There are many places in our solar system that can provide some clues: Earth and Gas Veterans Moon.
Life on evil planets like Earth
On Earth, hydrothermal vents, where the water of the frigid ocean in general is heated to hundreds of degrees by volcanic procedures, is the hotband of life.
The water is hot and has abundance of decomposed minerals, which encourages the development of bacteria and other simple organisms. Once they are present, large, more complex creatures adhere to quickly. There is a decent amount of evidence that suggests that a very first life has arisen on the earth in such areas.
If the Earth suddenly became an evil planet, the planet would have cooled down, and during months or a year, the entire ocean would be covered in snow. That ice will act as an insulator, which will slow down the loss of energy in space.
It is possible that it will take millions of years to freeze the deep parts of the ocean, and that hydrothrimal vents can make ooz for simple life so that the planets are geologically active as long as the planets are geologically active, which will probably be the case for at least one and billion years.
Life on wicked gas giants and their moon
Apart from the Earth, the moons of gas giants like Jupiter are considered the best place for life in our solar system.
However, wearing with tidal Jupiter, worn with icy exteriors, heats the interiors of the moon due to stress and other moon due to gravity interaction with tidal Jupiter. This heating can be very intense – the result is the 4th largest moon in Jupiter, which has become the most volcanic body in the solar system.
IO is not considered to hide an ocean in itself, but the salty oceans may be present on many moon in the solar system, including Jupiter’s Moon Europa, Colosto, Ghanimade and Saturn’s Moon Titan and Enseldus.
If a gas giant and its moon were removed from a solar system, it is completely possible that tidal heat could maintain the conditions required for life on the moon for billions.
While the life found on the moon of the wicked, earth or wicked gas giants is not like life, it will definitely be present to talk to captain Kirk, it may definitely be present. Therefore, while the company cannot be much for conversation, at least one possibility that these planets are in Some? As friends, they roam the universe.
