Which is bigger the moon or the milkyway?

Answer 1

Not even close.

Actually, the size basically goes like this:

Planet (i.e., Earth)

Solar System (has multiple planets)

Galaxy (i.e., Milky Way, has billions of solar systems)

Universe (contains billions of galaxies)

It's been theorized that there may be a multi-verse, which contains multiple universes, and maybe even multiples of those, but nobody really knows yet.
Universe is bigger.

Answer 2

The Milky Way is much larger in size than the Moon. The Milky Way is a barred spiral galaxy containing billions of stars, while the Moon is Earth's natural satellite and is much smaller in comparison. The Milky Way measures about 100,000 light-years in diameter, while the Moon is about 3,474 kilometers in diameter.

Answer 3

Considering the Moon is smaller than the Earth and the Earth is part of our Solar System and our Solar System is part of the Milky Way Galaxy, then I think the Moon is definitely smaller than our Milky Way.

The Moon has a diameter of 0.0058 light seconds
The Milky Way Galaxy has a diameter of 100,000 light years

Answer 4

No. The Pleiades is an open cluster of a few thousand stars within the Milky Way.

The Pleiades is a group of stars about 2 degrees across, at a distance of 600 light years. That means it is about 20 light years from one side of the Pleiades to the other, but that it still much less than the size of the Galaxy. From the Pleiades, the Sun would appear as a 9th magnitude star, with Sirius nearby at magnitude 6.

Answer 5

The minimum size an object needs to be a star is 0.075 solar masses or about 80 Jupiter masses.

So Jupiter needs to be 80 times bigger to become a star.

If Jupiter was 13 times bigger it would be a brown dwarf stellar object.

Answer 6

Yes, a neutron star is only a few miles long while a nebula can be over tens of millions of miles long depending on the nebula. Nebulae are massive expanses of gas where hundreds of stars are born while neutron stars a the remains of a dead star where the only the core is left.

Answer 7

Our Milky Way is a Galaxy. However there are Galaxies larger than our own, for example Abell 2029, which an elliptical Galaxy believed to be 60 times larger than our own Milky Way and the largest known to man.

Answer 8

Yes. But we must qualify the 'yes' a bit. If by star system you mean the 'local group' of galaxies, the neighbors of the Milky Way which is made up of perhaps 25 or 30 galaxies, then the answer clearly is no. The answer depends on the operational definition of 'star system'.

Answer 9

A galaxy is an island universe (as astronomers call it) composed of hundreds of billions of stars, and usually having a monster black hole at its center. The galaxy earth is in is the Milky Way Galaxy. Light takes 100th of a second to go across the diameter of Earth, but 100,000years to go across the diameter of a galaxy. Earth is a planet not a galaxy. Galaxies CONTAIN solar systems like ours. Earth is part of a solar system, and a solar system is a part of the Milky Way Galaxy.

Answer 10

Yes, by hundreds of times or more. Jupiter is the biggest planet in this solar system, but we have discovered over 400 "exoplanets" - planets that are orbiting other stars - and most of them are larger than Jupiter.

The smallest possible star capable of hydrogen fusion would be dozens of times more massive than Jupiter.
