About 100,000 light years in diameter and 10,000 light years thick.
No. The Milky Way is believed to be a barred spiral galaxy.
It's difficult to define a galaxies size, as there is no real cut off point. From estimations, the Andromeda is about twice as large as the Milky Way.
It looks like a spiral. Edit: Why does it look like a spiral? Here's one complication : The Milky Way Galaxy must have rotated over 50 times so far, at our distance from… the centre. The outer parts take longer to orbit than the inner parts. So why are the spiral arms so clear and not messy and twisted up? You can see this isn't such a simple question after all. The important thing is that the spiral arms contain a lot of new, bright stars. The process that creates the new stars is not easy to understand, but the point is that the spiral effect is due to new stars that are constantly being created. So, a spiral effect appears and is not lost as the Galaxy keeps rotating. The theory involves "density waves". Be warned it's a bit complicated, but I've given you the basic idea.
No, Milky Way is a barred spiral.
The Milky Way galaxy will collide with Andromeda, but it will take about a 2 billion years until they collide and finish. Earth will not get blown up, but by then, the sun wil…l probably be out of hydrogen and expand. Then earth will be engulfed and all life will die.
An atmosphere occurs when gases are held in a gravitational field by a body. The Milky Way is a galaxy not a planet or star and does not have an atmosphere of its …own.
cause of the depth of the water is what makes the color of the ocean along with what lies underneath it, the Palau Milky Way is not sand, it's white limestone mud. white limes…tones are free from impurities, but they generally contain small quantities of other minerals than calcite which affect their color. Many limestones are yellowish or creamy, especially those that contain a little iron oxide or iron carbonate or clay. They call it Milky Way because it is the color of Milk.Sciencetist call our galaxy the milky way because in the past,when they looked in our galaxy it was all white like milk.
Yes. All constellations are in the Milky Way Galaxy
The Sun is about 332,946 times more massive than the Earth. It is about 1,300,000 times the volume of Earth. As for the Sun and the Milky Way - The Milky way is composed o…f roughly 100 billion stars, so one can say that because the Sun is an average star, the Milky Way is, very roughly, 100 billion times more massive than the Sun. Another viewpoint: The latest best estimates have the Milky Way Galaxy containing about 500 billion stars. Using that number and a more accurate way of estimating the total mass of the stars gives: Total mass of our Galaxy is about 1.9 thousand billion times the mass of the Sun. Notice that's an estimate of the total mass of the Galaxy, including dust and gas. Then again there's "dark matter" of course, but let's keep it simple.
The name is from the Greek root galaxias [γαλαξίας], meaning "milky," a reference to the milky way galaxy. They referred to it as "milky" because of the faint white a…ppearance on the night sky. It looks like spilled milk. There are a number of ancient legends where milk is involved in its creation.
No, the Milky Way does not contain "other" galaxies. The Milky Way is a galaxy unto itself. It has two small, irregular "sattelite" galaxies associated with it called the Larg…e Magellanic and Small Magellanic Clouds, but they are not visible from the Northern Hemisphere in this epoch. The next nearest galaxy is Andromeda, which is about 2.5 million light years away. It is estimated that their are 100 billion galaxies in the known universe.
The Milky Way is the home galaxy of the solar system.Its a barred spiral shape galaxy. It contains 100-400 billion stars and at least 50 billion planets.The stellar disk of th…e Milky Way galaxy is approximately 100,000 light years.The Milky Way is part of the local group of galaxies and is one of around 200 billion galaxies in the observable universe.
The Milky Way Galaxy is classed as a spiral galaxy as it's appearance is of a spiral with looser outer stars becoming denser the closer you get to the centre. As a picture i…s worth a thousand of my words, the the related link for a generated picture of our galaxy. Note: This is a computer generation of what we believe the galaxy looks like and not a real one (as we have not ventured past our own solar system, let alone the galaxy).
It depends on where in Milky Way you measure from, but the closest to us is the Canis Major Dwarf Galaxy. In fact, we are closer to it than we are to the center of the Milky W…ay by several thousand light-years, and it is currently in the process of being incorporated into the Milky Way. The next spiral galaxy to us is the king of our local group--Andromeda. The Andromeda Galaxy is about 2.5 million light years away, and is only a little bit larger than the Milky Way.
Well if the sun were the size of a grapefruit we would not have anything in this solar system to compare it to, so lets make the sun the size of a grain of sand (2mm), t…he milky way would then be the size of our Sun, which is just over 109 the size of earth... however we are basing this off width, being that the Milky Way is disk shaped.
