Which statement best describes why the Milky Way is shaped a certain way?
Which statement best describes why the Milky Way is shaped a certain way? The gravitational forces from the center of the Milky Way cause stars and solar systems to orbit around the center of the galaxy. The gravity from the sun causes all of the other stars and solar systems to orbit it.
What is the general shape of the Milky Way galaxy group of answer choices?
What is the general shape of the Milky Way galaxy? a flattened disk in a spiral shape with a bulge in the center.
What are the three main types of galaxies?
Astronomers classify galaxies into three major categories: elliptical, spiral and irregular. These galaxies span a wide range of sizes, from dwarf galaxies containing as few as 100 million stars to giant galaxies with more than a trillion stars.
What do all stars have in common?
Basically, stars are big exploding balls of gas, mostly hydrogen and helium. Our nearest star, the Sun, is so hot that the huge amount of hydrogen is undergoing a constant star-wide nuclear reaction, like in a hydrogen bomb.
Which galaxies are the smallest?
The smallest independent structures known today are Segue 1 and Segue 3. Only approximately 1000 stars are present in the entirety of dwarf galaxies Segue 1 and Segue 3,…
What is a very small star called?
Smallest stars by type The red dwarf stars are considered the smallest stars known, and representative of the smallest star possible. Brown dwarf. Cha 110913-773444. 2004. Brown dwarfs are not massive enough to build up the pressure in the central regions to allow nuclear fusion of hydrogen into helium.
What is a mini galaxy?
A dwarf galaxy is a small galaxy composed of about 1000 up to several billion stars, as compared to the Milky Way’s 200–400 billion stars.
Is Samsung making a mini phone?
After all, the Galaxy S10e was essentially the Android equivalent of an iPhone 12 Mini — but Samsung abandoned the line before it even had a chance to take hold. It’s too late now, of course, but the Mini is more proof that Samsung made a huge mistake by skipping the Galaxy S20e.
What does galaxy mean?
A galaxy is a huge collection of gas, dust, and billions of stars and their solar systems. A galaxy is held together by gravity. Our galaxy, the Milky Way, also has a supermassive black hole in the middle. Some scientists think there could be as many as one hundred billion galaxies in the universe.
What are the 5 types of galaxies?
These galaxies are composed of stars, gas and dust held together with gravitational forces. Each galaxy type is named for its shape, making it easy to identify which type of galaxy you are looking at. You may already be familiar with the galaxies: spiral, barred spiral, elliptical and irregular.
What are the 6 types of galaxies?
There are four main categories of galaxies: elliptical, spiral, barred spiral, and irregular. These types of galaxies are further divided into subcategories while at the same time other types of galaxies exist based on their size and other unique features.
What type of galaxy do we live in?
Milky Way Galaxy
