Planet Earth Solar System Milky Way Galaxy

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.

Planet earth solar system milky way galaxy.

A galaxy is a system of solar systems and other stars. Let s look at the basics. This means there are potentially thousands of planetary systems like our solar system within the galaxy. The galaxy that contains the earth and its solar system is called the milky way.

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. Our galaxy the milky way also has a supermassive black hole in the middle. The first two are easy to grasp but. The milky way galaxy the major arms consist of the highest densities of both young and old stars.

Orbit of the solar system. One orbital period of the solar system lasts between 225 and 250 million years. The sun s orbital radius is roughly 8 600 parsecs or slightly over half way to the galactic edge. This galaxy is thought to contain more than 200 billion different.

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. It s a small part of the milky way galaxy. Galaxies like solar systems are held together by gravity.

There is evidence that extragalactic planets exoplanets farther away in galaxies beyond the local milky way galaxy may exist. Earth is well equipped as a planet and ideally placed in our solar system and galaxy to support life as we know it. We live on a planet called earth that is part of our solar system. A galaxy is held together by gravity.

But where is our solar system. 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. Fact that earth based observations were complicated by the fact that the earth is embedded in the solar system. The milky way galaxy is a very very big place.

Within it there are at least 100 billion stars and on average each star has at least one planet orbiting it. It was only after many centuries. Our milky way galaxy is just one of billions of galaxies in the universe. The average diameter of the orbit of the solar system relative to the galactic center.
