There are also the five dwarf planets pluto eris makemake haumea and ceres.

Solar system milky way galaxy planets. Like more than two thirds of the known galaxies the milky way has a spiral shape. At least 100 billion planets exist in the milky way galaxy. Our galaxy the milky way is typical.

Our sun is just one star among the hundreds of billions of stars in our milky way galaxy. Many people are not clear about the difference between our solar system our milky way galaxy and the universe. The annotated artist s concept illustrates the new view of the milky way.

Let s look at the basics. Our solar system which includes the sun earth and seven other planets is part of this galaxy called you guessed it the milky. The milky way is the galaxy that contains our solar system with the name describing the galaxy s appearance from earth.

The milky way galaxy has 4 major spiral arms which are sights of strong star formation. And it s all held together by gravity. There are many more minor spiral arms as well.

A hazy band of light seen in the night sky formed from stars that cannot be individually distinguished by the naked eye the term milky way is a translation of the latin via lactea from the greek γαλακτικός κύκλος galaktikos kýklos milky circle. It has hundreds of billions of stars enough gas and dust to make billions more stars and at least ten times as much dark matter as all the stars and gas put together. Using infrared images from nasa s spitzer space telescope scientists have discovered that the milky way s elegant spiral structure is dominated by just two arms wrapping off the ends of a central bar of stars.

Our sun is currently in such a location just outside a spiral arm named the orion arm. 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. The most well known planets in our milky way are the eight planets of our solar system namely mercury venus earth mars jupiter saturn uranus and neptune.
