Answer

Explanation:

The correct answer is option 'B' - Galaxy.

Definition of a Galaxy:
A galaxy is a vast system of billions or even trillions of stars, along with gas, dust, and various celestial bodies, all held together by gravitational forces. They are the building blocks of the universe and can be found throughout the cosmos.

Millions of Stars:
A star is a massive, luminous sphere of plasma held together by its gravity. There are billions of stars in the universe, each with its own unique characteristics, such as size, temperature, and brightness. When millions of stars come together, they form a galaxy.

Characteristics of a Galaxy:
1. Size: Galaxies can range in size from small dwarf galaxies containing a few million stars to giant galaxies with hundreds of billions of stars.
2. Shape: Galaxies come in various shapes, including spiral, elliptical, and irregular.
3. Components: Apart from stars, galaxies also contain other celestial objects like planets, asteroids, comets, and even black holes.
4. Gravitational Forces: The gravitational forces between stars and other celestial bodies within a galaxy are responsible for holding them together.

Types of Galaxies:
1. Spiral Galaxies: These galaxies have a distinct spiral structure, with arms winding out from a central bulge. The Milky Way, our own galaxy, is a spiral galaxy.
2. Elliptical Galaxies: These galaxies have a more rounded or elliptical shape. They lack the spiral arms and have a smooth, featureless appearance.
3. Irregular Galaxies: Irregular galaxies do not have a defined shape and often appear chaotic or distorted. They can be the result of interactions between galaxies or other gravitational disturbances.

Importance of Galaxies:
1. Home to Stars and Planets: Galaxies are the birthplaces of stars and planets. Within the vast expanse of a galaxy, new stars are constantly forming, and some of these stars may have planets orbiting around them.
2. Study of the Universe: By studying galaxies, astronomers can gain insights into the formation and evolution of the universe. Galaxies provide valuable information about the distribution of matter and the expansion of space.
3. Cosmic Evolution: Galaxies are crucial in understanding the cosmic evolution of the universe. By observing galaxies at different distances, astronomers can study how galaxies have changed over time and how they have influenced each other.

In conclusion, millions of stars come together to form a galaxy, which is a vast system of stars, gas, dust, and other celestial bodies held together by gravitational forces. Galaxies play a crucial role in our understanding of the universe and its evolution.

Answer

Million of stars together make a galaxy. Our solar system falls under the milky way galaxy.

Answer

It's a galaxy
many stars together will form a galaxy

Answer

Millions and billions of stars, gas, dust, meteors etc., held together by friction and gravitational force make a galaxy.. so, correct answer is B*
