Black holes, stars, planets, proto-planets, large and small agglomerates (comets, meteors, interstellar dust), gas clouds.
No. Stars are not fixed objects.
The Milky Way galaxy is made of stars, dust clouds, planets, comets, and other astronomical objects, probably including a black hole at the center, but mostly stars.
Scientists determine the amount of mass in our galaxy by studying the movements of stars and other celestial objects. By observing how these objects move and interact with each other, scientists can calculate the total mass of the galaxy. This helps us understand the structure and dynamics of our galaxy.
That sounds like a description of a galaxy.
Super Mario Galaxy was made on 2007.
galaxy are group of billions of stars
The galaxy is not a planet. The galaxy is MADE of millions and millions of stars and planets.
The three major ones are:-Supermassive black holeStarsPlanets
stars
Every galaxy is made up of millions of stars. An elliptical galaxy consists of predominately old stars,. See related question.
Each individual object (such as a star) revolves around the galactic center according to the laws of celestial mechanics. As a result, the objects closer to the center of the galaxy take less time for a complete revolution than the objects further out; the galaxy rotation is differential, meaning it does not rotate as if it were a solid object.
Yes, with the help of powerful telescopes, scientists can observe and study objects outside of our galaxy, such as other galaxies, stars, and nebulae.
