What are three sizes for galaxies?
Galaxies can be classified into three main sizes: dwarf galaxies, which are small and contain less than a few billion stars; Milky Way-sized galaxies, which are intermediate in size and contain a few hundred billion stars; and giant galaxies, which are massive and can contain trillions of stars.
Do all galaxies contain billions of stars?
Yes, most galaxies contain billions of stars. For instance, our Milky Way galaxy is estimated to have around 100 to 400 billion stars. However, there are smaller galaxies, known as dwarf galaxies, that may contain as few as a few million stars. Despite this variation, the majority of galaxies are star-rich and typically hold vast numbers of stars.
Can the approximate size of a galaxy be measured by the Doppler effect?
false Irregular galaxies are different from elliptical and spiral galaxies because the contain very few stars. Fasle
Are some galaxies very small and have only a few thousand stars?
These small galaxies are believed to be the result of collisions between larger spiral galaxies. During such collisions pieces of the spiral arms get flung out into space, becoming small irregular galaxies.
How many stars on the galaxies?
A dwarf galaxy can have a few million stars; a huge galaxy can have a trillion stars or more.
How many stars are needed to form a galaxy?
Typical galaxies range from dwarfs with as few as ten million stars up to giants with one trillion stars, all orbiting the galaxy's centre of mass. Galaxies can also contain many multiple star systems, star clusters, and various interstellar clouds.See link for more information.
How many stars does the Cartwheel Galaxy contain?
Answer: These numbers are only estimates of course. Over the years estimates of the numbers of stars in our Galaxy has gradually increased. Good sources give various numbers ranging from about 200 billion up to 500 billion. I think the higher numbers are more likely to be correct. Our Milky Way Galaxy is, very roughly, average. So, a typical galaxy should contain a few hundred billion stars. Answer: It is very hard to give a "typical" number. The answer above refers mainly to our own galaxy, but there are lots of galaxies that are much, much smaller - and there are also giants that are much larger than our galaxy. Thus, a typical galaxy may contain anywhere between about 10 million stars, and a trillion (i.e., a million million) stars, although you'll probably find galaxies with more than that.
How many stars are there in each Galaxy?
Over 100 billion just in ourgalaxy. So more than 100 billion stars in a galaxy!
How many stars in the average galaxy?
Galaxies vary a lot in size, from dwarf galaxies that have a few hundred million stars, to huge galaxies with a hundred trillion stars. (That's a ratio of about 1 to a million.)Our own galaxy has somewhere between 200 and 400 billion stars. Actually, most galaxies are quite a bit smaller than our own galaxy, since dwarf galaxies occur in larger numbers.
How many stars, on average, are contained in a galaxy?
Oh, that's a delightful question! Well, galaxies come in all shapes and sizes, each as unique as a happy little tree in a painting. On average, a galaxy can have anywhere from a 100 billion to a trillion stars twinkling within it — each one adding its own touch of beauty to the cosmic masterpiece.
Can a nebula contain galaxies?
No, a nebula is only a few light-years across while a galaxy is thousands of light-years across.
How many stars are in galaxies?
There are billions of stars in a galaxy. Scientists are saying that they cant give any accurate answer to this question.Answer:Galaxies come in a range of sizes and the number of stars in them is not consistent. Dwarf galaxies may have as few as ten million (107) stars, giant galaxies may have a hundred trillion (1014) stars. Our own Milky Way has 200-400 billion stars (200-400 x109)
