Planet Earth Solar System Milky Way Galaxy

It s a small part of the milky way galaxy.

Planet earth solar system milky way galaxy.

A galaxy is a system of solar systems and other stars. Many people are not clear about the difference between our solar system our milky way galaxy and the universe. Let s look at the basics. It was only after many centuries.

Our solar system consists of our star the sun and its orbiting planets including earth along with numerous moons asteroids comet material rocks and dust our sun is just one star among the hundreds of billions of stars in our milky way galaxy. This means there are potentially thousands of planetary systems like our solar system within the galaxy. In galaxies the solar systems are separated by vast sections of mostly empty space. Fact that earth based observations were complicated by the fact that the earth is embedded in the solar system.

One orbital period of the solar system lasts between 225 and 250 million years. We live on a planet called earth that is part of our solar system. Orbit of the solar system. This galaxy is thought to contain more than 200 billion different.

Earth is well equipped as a planet and ideally placed in our solar system and galaxy to support life as we know it. 14 15 the nearest exoplanets are located 4 2 light years 1 3 parsecs from earth and orbit proxima centauri the closest star to the sun. The artist s concept also includes a new spiral arm called the far 3 kiloparsec arm discovered via a radio telescope survey of gas in the milky way. The milky way galaxy is a very very big place.

The average diameter of the orbit of the solar system relative to the galactic center. Our galaxy the milky way also has a supermassive black hole in the middle. The sun s orbital radius is roughly 8 600 parsecs or slightly over half way to the galactic edge. But where is our solar system.

The first two are easy to grasp but. Within it there are at least 100 billion stars and on average each star has at least one planet orbiting it. Our milky way galaxy is just one of billions of galaxies in the universe. A galaxy is held together by gravity.

A galaxy is a huge collection of gas dust and billions of stars and their solar systems. The product of some 4 6 billion years of cosmic construction our planet is. The minor arms are primarily filled with gas and pockets of star forming activity. The galaxy that contains the earth and its solar system is called the milky way.

The milky way galaxy the major arms consist of the highest densities of both young and old stars.
