Large galaxies typically have hundreds of billions to over a trillion stars, such as the Milky Way. Small galaxies, like dwarf galaxies, contain only millions to tens of billions of stars. Size can also be determined by the physical extents of the galaxy, with large galaxies having a larger diameter and mass than small ones.
Our Milky Way has a diameter of 100,000 light-years, and contains somewhere between 200-400 billion stars. Other galaxies can have anywhere from about 10 million stars to about 100 trillion stars; a dwarf galaxy is much smaller than the Milky Way, while the largest galaxies can have a diameter of several hundred thousand light-years.
No. The term "universe" can be a slippery concept to try and get ahold of, but here's
a working definition: The "universe" is all of the time and space that ever did, does,
and will exist, as well as all the matter and energy in it. In another word, the "universe"
means "everything". So, anything and everything you can think of is in the universe,
and nothing is bigger than it. Except perhaps the One who Created it, but that discussion
belongs in other categories of questions.
Next to that, a mere "galaxy" is puny. A "galaxy" is just a few hundred billion stars,
and there are probaly several billion galaxies in the universe, so you can see that
a galaxy doesn't amount to much at all. (? ! ?)
The Milky Way has a diameter of about 100,000 light-years. Each light-year is the distance light travels in a year, at 300,000 km/sec - so a light-year is about 9.5 million million kilometers.
Our galaxy is shaped like a disk or two dinner plates stacked facing each other. The central hub is about ten thousand light years thick, but out where we are the galaxy thins to three thousand light years wide.
100,000 light years across. That is close to 600,000,000,000,000,000 (six hundred quadrillion) miles, or 9x1020 meters.
The universe is so, extremely giant, it's pretty much impossible to actually imagine how big it really is. The best thing to do is to start with something small and work up from there; so let's start with the Earth. Earth may seem a giant place to us humans, but no where near in size to the universe. But, at approximate, the Earth is about 8,000 miles wide. If you drove a transglobal tunnel down through the middle of the Earth (which is not possible, but just imagine it) at a non - stop speed of 60mph, then you'd pop out the other side in about 5.5 days. Which isn't that long with what will come up. Now, lets try the distance to the Earth to our Moon. Every month, the Moon will get further and closer away from us. But, on average, the distance from Earth to Moon is 240,000 miles. Travelling at a speed of 60mph, you'd get to the Moon in about 168 days, which is quite long. Now, lets try something even longer; the Earth to the Sun. This distance is about 92 million miles, and would take you about 176 years to get there by 60mph. Now, to cross our galaxy, the Milky Way. By going at 60mph, you'd have to travel 621 million billion miles to cross the Milky Way. It would take 1 million billion (or, to be more precise, 1,181,401,000,000,000) years to accomplish. So, this tells us that a space car would be pretty cool, but 60mph is a pathetic speed for travelling across space. So, we'll think of something super - duper fast; light. The speed of light can travel a mind - blowing 186,000 miles in 1 second, at approximate. We're talking about a speed so fast it could travel 6 trillion miles if it kept on moving at it's normal speed for 1 year. This is known as a 'Light year'. But, even with our super fast speed of light travel, it'd take it about 100,000 years at approximate to cross the Milky Way. And, to move onto our universe. With out most powerful telescopes, we can measure that the universe is 15 billion Light years in every direction. So, at the speed of light, it'd still take at least 30 billion years to cross the universe.
For a conclusion, it's pretty much impossible to measure out the proper size of the universe.
It never ever ends. It goes on and on and on ........
It is theorized to be infinite but there is no way to know with our technology because we can only see a certain distance using different types of technology.
Per wikipedia: The stellar disk of the Milky Way galaxy is approximately 100,000 light-years in diameter, and is believed to be, on average, about 1,000 light-years thick. If you include the gaseous cloud outside of the galaxy proper, it is about 180,000 light-years. In English units, one light year is about 5.9 x 1012 miles, so the diameter of the Milky Way galaxy is about 590 x 1015 miles in diameter, or 590,000,000,000,000,000 miles.
If the question was posed by my kid, back when he was 5 or 6 and really into that sort of thing, my answer would be "As big as your mind and imagination wants it to be" which, in my mind, is a lot bigger than 590x 1015 miles.
The term "galaxy" typically refers to a large system of stars, gas, and dust, while a "solar system" refers specifically to our own system, with the Sun and its planets. There are no small galaxies within our solar system since galaxies are much larger in scale compared to solar systems.
The Andromeda Galaxy (also known as M31) is the closest spiral galaxy to the Milky Way. It is located about 2.5 million light-years away and is on a collision course with the Milky Way in the distant future.
The closest galaxy to the Milky Way is the Andromeda Galaxy, also known as M31. It is located about 2.5 million light-years away from us and is expected to collide with our galaxy in about 4.5 billion years.
in general no but it is an average sized planet, and very small compared to our sun, galaxy etc.
The Draco Dwarf Galaxy is a faint and small galaxy located in the constellation Draco. It appears as a dim smudge in the night sky when viewed through a telescope. Its stars are spread out over a large area, giving it a diffuse and ill-defined appearance.
Theoretically they can be as large as a small star or as large as a galaxy
No. It is a small galaxy.
The Large Magellanic Cloud is a galaxy, whereas the Small Magellanic Cloud is a dwarf galaxy.
The Andromeda galaxy is the nearest large galaxy. There are several "dwarf" galaxies which are nearer, including the Small and Large Magellanic Clouds
B.) A giant elliptical galaxy
Here are some galaxies (all of them part of the Local Group): The Milky Way, our own galaxy The Andromeda Galaxy, another large galaxy The Triangulum Galaxy, another large galaxy The Large Magellanic Cloud, a dwarf galaxy close to the Milky Way The Small Magellanic Cloud, another dwarf galaxy close to the Milky Way
The closest spiral galaxy to us is known as the Andromeda galaxy.The Large and Small Magellanic Cloud closer,but there not spiral galaxy there dwarf galaxies.The Andromeda galaxy is about 2,000,000 light years away,while the Large Magellanic Cloud is 160,000 light years away,and the Small Magellanic Cloud is 200,000 light years away.That is why the Large Magellanic Cloud looks larger.
They are all suns for far off Galaxy's.
One of the larger ones.
The Andromeda galaxy (M31), the Large Magellanic Cloud, the Small Magellanic Cloud.
Milky Way; Andromeda Galaxy; Large Magellanic Cloud; Small Magellanic Cloud; Triangulum Galaxy. (These five are part of the Local Group.)
We'll never know. Small galaxies are easy to overlook in the distances of space, and can be misidentified. At some point, there's not much difference between a "small galaxy" and a "large cluster". For example, is the "Small Magellanic Cloud" a small galaxy, or just a large stellar cluster orbiting the Milky Way?
