Scientists think planets that don't orbit any star, called free-floating planets or rogue planets, can harbor life too. These planets originally form around stars like any other but get kicked out of their system at some point due to gravitational effects of giant planets within.18 Jan 2022
Which planet could support life?
Earth Understanding planetary habitability is partly an extrapolation of the conditions on Earth, as this is the only planet known to support life.
Can a rogue planet enter our solar system?
In most cases, a rogue planet entering our system would spin out again, possibly dragging one of our own native planets along with it. In roughly 40% of cases, however, the rogue could be captured, either without perturbing the orbits of nearer planets or by booting one of our own planets out in the process.
What would happen if a rogue planet entered the solar system?
The rogue planet might not push us out of the habitable zone, but it would bring us much closer to the Sun for very short and exceptionally hot summers. Those extreme summers would be followed by long and super cold winters. Quick summers would leave us less time to grow crops.
What would a rogue planet be like?
A rogue planet (also termed a free-floating planet (FFP), interstellar, nomad, orphan, sunless, starless, unbound or wandering planet) is an interstellar object of planetary-mass, therefore smaller than fusors (stars and brown dwarfs) and without a host planetary system.
How much longer will the Earth be habitable?
The upshot: Earth has at least 1.5 billion years left to support life, the researchers report this month in Geophysical Research Letters. If humans last that long, Earth would be generally uncomfortable for them, but livable in some areas just below the polar regions, Wolf suggests.
What is the most Earth like planet?

Why hasn’t a rogue planet destroyed the Solar System yet?
Yes, there could be billions of rogue planets inside our galaxy, but the chances of any one of them ever crossing our path are slim. And that's why a rogue planet hasn't destroyed the solar system yet.
Is planet 9 a rogue planet?
Others proposed that the planet was captured from another star, was once a rogue planet, or that it formed on a distant orbit and was pulled into an eccentric orbit by a passing star….Planet Nine.

Do rogue planets rotate?
So instead of orbiting a star, they go rogue and fly off into the Milky Way, possibly seeking fame, fortune and adventure, but keeping to the beat of their own drummer. A rogue planet is any planet that doesn't orbit a star. Instead of being a member of a solar system, it orbits the Milky Way on its own.
