An extragalactic planet, also known as an extragalactic exoplanet or an extroplanet, is a star-bound planet or rogue planet located outside of the Milky Way Galaxy. However, indirect evidence suggests that such planets exist. …
Will intergalactic travel ever be possible?
The technology required to travel between galaxies is far beyond humanity’s present capabilities, and currently only the subject of speculation, hypothesis, and science fiction. However, theoretically speaking, there is nothing to conclusively indicate that intergalactic travel is impossible.
What is the scariest planet in our solar system?
Welcome to TrEs-2b, the planet of eternal night. The darkest planet ever discovered orbiting a star, this alien world is less reflective than coal with a burning atmosphere – the air is as hot as lava.
Has rogue planet been found?
Astronomers have just detected four new Earth-sized exoplanets floating along near our Milky Way’s Galactic Bulge—the cluster of dust, gas, and stars at our galaxy’s center. But unlike Earth, these planets don’t belong to any solar system. They’re free-floating rogues.
What is there in intergalactic space?
The space between stars is known as interstellar space, and so the space between galaxies is called intergalactic space. Intergalactic space is as close as you can get to an absolute vacuum. There’s very little dust and debris, and scientists have calculated that there’s probably only one hydrogen atom per cubic meter.
What is the most beautiful planet in the universe?

Can a planet exist without a sun?
A Big Discovery It is the first really good evidence that planets without suns actually exist. It’s also exciting because this planet is very young. It could help scientists figure out what planets like Jupiter were like when they first formed. But there is something even more exciting about this planet.
Will a rogue planet ever hit Earth?
Only in the last couple of years, rogue asteroids such as Oumuamua and rogue comets such as Borisov whizzed through our solar system. It is unlikely a rogue planet would pass by us that close up. But it’s not beyond the realms of probability. Earth has so far escaped banishment from the Sun.
