No one knows. Astronomers are scanning the visible stars of our own Milky Way galaxy for planets orbiting faraway stars, but such planets would have to be nearly the size of Jupiter to be detected at such distances
The planets were formed in the Milky Way. Our Galaxy (Milky Way) is older than the planets of our solar system.
There are millions, possibly billions, of planets in the Milky Way. An exact number will never be known.
pluto,asteroids,stars,comets and dwarf planets Stars, gas, black holes.
No. There are dwarf planets in our own solar system that are smaller than Pluto and there are many undiscovered planets in the Milky Way that would be smaller than it, but are too far away to see.
Most planets that have been discovered are in the Milky Way
It is not known. Scientists are still not sure how many dwarf planets are in the solar system or how many true planets are in the galaxy. If estimates from our solar system apply elsewhere, however, the number is probably in the trillions.
Pluto is still in the Milky Way Galaxy.
Yes. There have been hundreds of planets discovered in other stars in the Milky Way. It has been estimated that the Milky Way likely contains hundreds of billions of planets.
there way to small to be planets
There are more than 350 known planets in the milky way, with only 8 in our solar system.
All the planets we know of... even those orbiting other stars... are in the Milky Way Galaxy.
Yes, Pluto is a dwarf planet in our solar system, and our solar system is contained within the Milky Way Galaxy.
