What is the relationship between the universe galaxies Solar Systems stars and planets?
Our solar system consists of the sun, and all astronomical objects bound in its orbit. A galaxy is a collection of billions of stars, gas, and dust. Our solar system is one of millions of solar systems found in our galaxy, the Milky Way. Galaxies are held together by gravitational attraction,much like a solar system.
So how many stars are there in the Universe? Stars are not scattered randomly through space, they are gathered together into vast groups known as galaxies. The Sun belongs to a galaxy called the Milky Way. Astronomers estimate there are about 100 thousand million stars in the Milky Way alone.
What’s the difference between a solar system and a galaxy?
The solar system consists of anything that orbits the sun or orbits the planets which orbit the sun. The moon of earth, for example, is a part of our solar system. A galaxy, on the other hand, is a huge collection of stars that are held together by gravitational attraction.
What is the relationship between planetary system planets and stars?
Planetary systems come from protoplanetary disks that form around stars as part of the process of star formation. During formation of a system, much material is gravitationally-scattered into distant orbits, and some planets are ejected completely from the system, becoming rogue planets.
Do stars turn into planets?
yes! A star can turn into a planet, but this is true only for a specific category of stars called brown dwarfs.
How is the galaxy different from the Solar System?
The universe is flat and is composed of 4.6% atoms, 24% cold dark matter, and 71.4% dark energy. A galaxy is a large collection of stars, gas, and dust kept together by gravity. Galaxies come in all sorts of different shapes and sizes. They can be elliptical, lenticular, spiral, dwarf, and irregular.
Is the Sun unique to the Milky Way galaxy?
Our Sun is one star among the billions in the Milky Way Galaxy. Our Milky Way Galaxy is one among the billions of galaxies in our Universe. You are unique in the Universe!
How are stars in different galaxies related to each other?
What is happening is similar to the interaction between the Earth and the Moon. The stars in both galaxies feel a tidal gravitational force from the other galaxy.
Are there other solar systems like our Solar System?
Other Solar Systems Our Milky Way Galaxy is just one of billions of galaxies in the universe. Within it, there are at least 100 billion stars, and on average, each star has at least one planet orbiting it. This means there are potentially thousands of planetary systems like our solar system within the galaxy!
