Planets Without Stars

Rogue planets or "Planets Without Stars" or wandering planets that don't circle around a particular star was said to be billions of them within our galaxy or the galaxy where our planet is.

"In the new paper,scientists have revealed that simulations suggest there could be BILLIONS of rogue planets in the milky way alone.Detecting them is a hard thing to do." /(Ancient Code)



" Astronomers say that their simulations indicate that there could be at least 16.5 billion rogue planets wandering around the Milky Way Galaxy,all of which belong to a total of around 100 Billion planets,give or take a million." (Ancient Code)

As the report says,scientists found some rogue planets but not all them because of not yet proven method to detect them.

"Rogue planets are planets without stars and thus orbit the galaxy directly. This makes them incredibly difficult to find because they don't reflect any starlight or are undetectable by common exoplanet detection methods.Yet science paved way to find just one such planet lurking in the dark about 80 light years away.The faint red glow of the rogue planet PSOJ318.5-22 was directly imaged by the Pan-STARRS PS1 telescope seeing that such rogue planets are hard to find,it makes sense that one is 6 times more massive than Jupiter,making it relatively easy to spot." (Medium)

Rogue planets are hard to find because they don't have stars and hidden lurking or wandering in the dark universe.Scientists detect planets through their stars or through a star.

"So,what can we do to spot  planets that don't orbit any stars? Well,last year [2018] it has been reported that two rogue exoplanets were spotted by astronomers thanks to the way their gravity bends the light that is being emitted from behind them.Infrared imaging has allowed astronomers to find outer rogue exoplanets.However,until now no more than 20 rogue planets have been discovered.Compared to 3,917 confirmed exoplanets orbiting a star,we see a massive discrepancy." (Ancient Code)

"Gravitational microlensing observations of 50 million stars in the Milky Way found 10 Jupiter-sized rogue planets.This helped scientists estimate that there are at least 2 rogue planets for every star in the galaxy.This means that there are potentially billions of rogue planets out there,lurking silently in the dark.Many of them are likely Earth-sized too." (Medium

"A rogue planet (also termed as interstellar planet,nomad planet,free-floating planet,unbound planet,orphan planet,wandering planet,starless planet,or sunless planet) is a planetary-mass object that orbits a galactic center directly.Sch objects have been ejected from the planetary system in which they formed or have never been gravitationally bound to any star or brown dwarf.The Milky Way alone have billions of rogue planets."
