The Solar System

On West Sagittarius arm of the Milky Way Galaxy, there is our Solar System. In that solar system there are 8 planets, 4 dwarf planets, 1 comet, and thousands of asteroids.


The planets are Mercury, Venus, Earth, Mars (the inner planets), Jupiter, Saturn, Uranus, and Neptune. The definition of a dwarf planet is a planetary-mass object that is object that is neither                  
a planet nor a satellite (the wikipedia definition). The dwarf planets are Pluto,  Eris, Haumea (egg planet), and Makemake. In the farthest reaches  of the Solar System, there is the Kuiper Belt, which is a belt of asteroids just past Pluto and Eris. The comet is Halley's Comet.  A comet is big ball of ice and dust that orbits a star. The sun is so big it takes up 99.98% of  the mass in the solar system. My favorite planet is Uranus because it's sideways. Instead of spinning on a top and bottom axis, it spins on a horizontal axis. 

What's your favorite planet?

It's usually very enjoyable and as well , jam-packed with a great time for me and my office co-workers to visit the blog a minimum of three times every week to read the newest guides you will have.
