A star and a galaxy are two distinct astronomical entities. A star is a luminous sphere of plasma held together by gravity, while a galaxy is a large system of stars, gas, and dust held together by gravity.

Is each star a galaxy?

No, each star is not a galaxy. Stars are individual celestial bodies that emit light and heat, while galaxies are vast systems of stars, planets, gas, and dust held together by gravity.


What is the most common star in the universe?

The most common type of star in the universe is a red dwarf star. These stars are smaller and cooler than our Sun, making up about 70-80 of all stars in the Milky Way galaxy.


How does star formation in the Milky Way contribute to the overall structure and evolution of our galaxy?

Star formation in the Milky Way plays a crucial role in shaping the galaxy's structure and evolution. New stars are born from clouds of gas and dust, which in turn create regions of intense radiation and stellar winds. These processes influence the distribution of matter and energy within the galaxy, leading to the formation of spiral arms, star clusters, and other structures. Over time, the life cycles of stars, including their deaths and explosions, release heavy elements into the interstellar medium, enriching it and providing the building blocks for future generations of stars and planets. This continuous cycle of star formation and destruction helps drive the evolution of the Milky Way and contributes to its overall structure and dynamics.


Does the galaxy orbit anything in the universe?

Yes, galaxies like the Milky Way are part of galaxy clusters that move through the universe, but they do not orbit a single object like planets orbit a star. Instead, galaxies are influenced by the gravitational forces of other galaxies and dark matter in the universe.


Does our galaxy orbit anything in the universe?

Yes, our galaxy, the Milky Way, is part of a group of galaxies called the Local Group. Within the Local Group, the Milky Way and the Andromeda galaxy are the two largest galaxies and they are actually moving towards each other. It is believed that the Local Group is also moving towards the Virgo Cluster, a larger cluster of galaxies. So, in a sense, our galaxy is moving within the universe, but it is not orbiting around a single object like a planet orbits a star.

Largest to smallest filament galaxy planet or star?

The order from largest to smallest would be: star, galaxy, planet, filament. Stars are individual astronomical objects, galaxies are collections of stars, planets are celestial bodies in orbit around stars, and filaments are structures in the cosmic web that connect galaxies.


What would be the size order of the astronomical objects Moon Neutron star White dwarf star and Galaxy?

Among the smallest astronomical objects is the neutron star, which is smaller than Earth's Moon, but larger than some. Next would be our Moon, followed by the shrunken White dwarf. Normal stars would then follow, and a galaxy is the largest , being a collection of millions or billions of stars. Neutron Star : as small as 20-24 km Moons : for Earth, 3400 km in diameter White Dwarf star : from about 5000 to 50000 km diameter Galaxies : 2000 to 100000 light-years across
