How may planets in the galaxy and what is the name for the planets?

Answer 1

Just 2. MAN & WOMAN

Answer 2

Infinity plus or minus one is the number of planets in the galaxy. No one knows for certain.
The word planet means wandering star.
For certain, there are 11 planets that have been successfully found over and over in our solar system. They are:
Mercury
Venus
Earth
Mars
(the planetesimils and asteroids of the asteroid belt do not count as planets in the same way the Moon does not count as a planet...1 - not large enough; and 2 - do not follow a specific linear orbit around the central gravity phenomenon, AKA the Sun)
Jupiter
Saturn
Uranus
Neptune (sometimes, it's Neptune and then Uranus as their orbits sometimes cross paths)
Pluto
Chiron
and Planet X

Answer 3

Current theory is that planets form along with stars as sort of a natural by-product of star formation. So we'd expect planets to be common around stars, at least whose formation took at least as long as it takes to form a planet (not all necessarily would). But to get a good idea of how common they really are, we need to examine a lot of stars and either find planets or convince ourselves that none exist. Since we've only been finding planets outside our solar system recently (in the past 5 years) and since we still can only find fairly large planets with small orbits, we are a long way from achieving this goal.

This doesn't stop astronomers from making guesses, though. We are really interested in this, since the number of planets in our galaxy affects the chances that we might find life elsewhere. Some astronomers think that nearly all stars have at least one planet. Others think that as few as 1 in 10 or 1 in 100 might be a better guess. Since there are 100 billion stars in our Milky Way galaxy, this means that the guesses would expect there to be between 1 billion to 100 billion stars with planets.

You also need to guess how many planets are found around each such star. Our sun has 8 or 9, but we might have more or less than normal. I'd guess maybe between 1 and 5 planets/star-with-planets, so I'd guess between 1 billion planets and 500 billion planets.

Bear in mind that these numbers are really only guesses, and we have almost no evidence for any of them. There are basically just astronomers guessing according to what they'd like there to be (some of us want lots of planets, of course, so our guesses are probably too high).

If you want to read more, try "Astronomy Today" by Chaisson and McMillan or "The Cosmic Perspective" by Bennett, Donahue, Schneider and Voit. Both textbooks have sections about this (and I'd expect most introductory astronomy texts would, as well).

Sorry the numbers are so vague. Stay tuned, because I beleive that we will be able to improve these guesses a lot in the next few years as we find more planets outside out system!

Answer 4

You question impies that there is only one galaxy. so either you don't know that there are billions of galaxies in the universe or you meant to ask about our own galaxy (the milkey way). Or perhaps maybe you meant to say "the universe" instead of "the galaxy"

so how many planets are in our own galaxy?
the answer is hundreds of millions of them.
Over the past decade, astronomers have discovered more than 100 planets orbiting around stars other than our Sun. So far, they primarily have only studied relatively nearby stars (closer than 200 light-years), but unless there is something special about our local neighborhood, planets should be found around more distant stars as well.

Answer 5

We have no idea how many planets are in our galaxy of 100 billion suns. The ones we have detected so far (maybe about 100) are referred to as "extrasolar planets." Even if only 10 percent of those 100 billion suns had planets (a conservative estimate in my opinion), that would put it around 10 billion planets. We could even name one after you!

Answer 6

I'm assuming you mean the Milky Way by "the galaxy"
Anyway, the number of planets is nine.They are:
Mercury
Venus
Earth
Mars
Jupiter
Saturn
Uranus
Neptune
Pluto

Answer 7

except the planets in our solar system there are other 179 planets that have been detected and they have to be in our Galaxy

.for all the info visit the source, and get their names which in general are numbers, like;
HD 142 b, HD 1237 b, HD 3651 b, etc, etc,

Answer 8

i dont know abt other galaxies but in milky way (our galaxy) there are 9 planets....murcury, venus, earth, mars, jupiter, saturn, uranus, neptune, pluto

Answer 9

9: Mercury, venus, earth, mars, jupiter, sartun, urunas, neptune, and pluto.

Answer 10

I suggest you accept Jesus as your saviour and ask him when you get to Heaven. He is the only one I know who will be able to answer this correctly
